66500: remaining budget for unfinished bungalows

hope this helped and good luck :D

Answer 2

The remaining budget for unfinished bungalows is $66500

What are arithmetical operations?

The four basic arithmetic operations in Maths, for all real numbers, are: Addition (Finding the Sum; '+') Subtraction (Finding the difference; '-') Multiplication (Finding the product; '×') Division (Finding the quotient; '÷')

Given that, A total of $114,000 will be evenly spent to build 12 Bungalows, the first 5 bungalows have been completed and paid. We need to find the amount available for the remaining bungalows.

Amount used in each bungalow;

114000/12 = $9500

Therefore, each bungalow will need $9500

Amount used = $9500 × 5 = $47500

Amount remaining for remaining bungalows = $114,000 - $47500 = $66500

Hence, $66500 is remaining budget for unfinished bungalows.

The radius of the earth is 4000 miles. How fast is someone on the equator moving compared to someone at the north pole due to daily rotation of the Earth (in miles per hour)?

Answers

Answer: speed at the equator =

1047.33 miles per hour

Step-by-step explanation:

The radius of earth is 4000miles

The earth rotates on its axis, hence we calculate the circumference at the equator

Circumference, C = 2 π R

C = 2 x 3.142 x 4000miles

C = 25,136 miles

Since the total time of one complete rotation about it's axis is 24hours

Hence, the speed at the equator is

speed = 25,136/24 = 1047.33 miles per hour

The speed of the person on the equator due to daily rotation of the earth is;

Speed = 1047.221 miles per hour

We are told that the radius of the earth is; R = 4000 miles.

Formula for circumference is;

C = 2πR

Thus;

C = 2 × π × 4000miles

C = 25,132.74 miles

C ≈ 25133 miles

Now, the time it takes for the earth to complete one full rotation about it's axis is 24 hours.

We know that formula for speed is;

speed = distance/time

Thus;

Speed on the equator is;

speed = 25133/24 = 1047.221 mph

Final answer:

The solutions of the differential equation y'' + y = sin(x) are y = cos(x), y = (1/2)sin(x), and y = -(1/2)xcos(x).

Explanation:

To determine which of the given functions are solutions of the differential equation y'' + y = sin(x), we can substitute each function into the equation and check if it satisfies the equation. Let's go through each option:

Substituting y = sin(x) into the equation, we get -sin(x) + sin(x) = sin(x), which is not true. So, y = sin(x) is not a solution.

Substituting y = cos(x) into the equation, we get -cos(x) + cos(x) = sin(x), which is true. So, y = cos(x) is a solution.

Substituting y = (1/2)sin(x) into the equation, we get -(1/2)sin(x) + (1/2)sin(x) = sin(x), which is true. So, y = (1/2)sin(x) is a solution.

Substituting y = -(1/2)xcos(x) into the equation, we get (-1/2)xcos(x) + (1/2)xcos(x) = sin(x), which is true. So, y = -(1/2)xcos(x) is a solution.

Therefore, the solutions of the differential equation y'' + y = sin(x) are y = cos(x), y = (1/2)sin(x), and y = -(1/2)xcos(x).

The probability you'll see a falling star in the sky over the course of one hour is 0.44. What's the probability you'll see one over half an hour?

Answers

Answer:

Probability so see one falling star over half an hour is 0.25

Step-by-step explanation:

An hour can be taken as two half hours so we can write the probability to see a falling star as

(1-P)*(1-P) = 1 - 0.44

( 1 - P )² = 0.56

1 - P = [tex]\sqrt{0.56}[/tex]

Use the graph that shows the solution to
f(x)=g(x) .

f(x)=−3/4x^2+3x+1

g(x)=2x

Answers

Graph A is the correct representation, as it aligns with the functions f(x) and g(x), resulting in the accurate intersection point (2, 4). Graph B does not accurately represent the functions based on the reported intersection point (4, 1).

The correct graph can be determined by analyzing the given functions and the specified intersection points. The functions are f(x) = -3/4 * x^2 + 3x + 1 and g(x) = 2x, and the reported intersection points are (2, 4) for graph A and (4, 1) for graph B.

To verify the accuracy, substitute the x-values into both functions:

Graph A (Intersection at (2, 4)):

f(2) = -3/4 * (2)^2 + 3 * 2 + 1 = 4

g(2) = 2 * 2 = 4

Both functions align, confirming the correctness of the reported intersection point.

Graph B (Intersection at (4, 1)):

f(4) = -3/4 * (4)^2 + 3 * 4 + 1 = 1

g(4) = 2 * 4 = 8

There is a discrepancy here, as the y-values do not match. Therefore, graph B does not accurately represent the functions f(x) and g(x).

In conclusion, graph A is correct since it accurately reflects the given functions and results in the reported intersection point (2, 4).

Janay is constructing a triangle using wire an art project.She has 3 inches of purple wire and 7 inches of pink wire.Janay is going to buy some blue wire for the third side of her triangle

Answers

Final answer:

For Janay's art project, the blue wire must be longer than 4 inches and shorter than 10 inches to create a triangle. This is based on the Triangle Inequality Theorem, which states that the length of any side of a triangle should be less than the sum of the lengths of the other two sides, but more than the difference of the two sides' lengths.

Explanation:

To determine how long the blue wire should be for Janay's art project, we need to understand a rule in geometry related to triangles, specifically the Triangle Inequality Theorem. This theorem states that the length of any side of a triangle must be less than the sum of the lengths of the other two sides.

Here, we have side lengths of 3 inches (purple wire) and 7 inches (pink wire), so the blue wire can be any length that is less than 3+7=10 inches, and more than |7-3|=4 inches. So the blue wire should be more than 4 inches and less than 10 inches to form a triangle.

This ensures that Janay will be able to form a valid triangle for her art project. If the length of the blue wire is less than 4 inches or greater than 10 inches, a triangle cannot be formed.

The sun subtend an angle at 35degree from the centre of the earth whose distant from the centre of the earth is 382,100km. Find the diameter of the sun

Answers

Study the figure attached below:

Answer:

240951.33km      

Step-by-step explanation:

For this type of question first we need to draw the figure as shown in the attached file (Figure.1).

Looking at the figure, we can see that triangle ABC is formed by bisecting the angle 35 degree (i.e. if the angle is bisected, it will divide into two equal parts, so 35 degree will divide into two equal parts of 17.5 degree).

As the triangle ABC is a right triangle, so we can use the trigonometric ratios to find the diameter of the sun.

[tex]tan(\theta )= \frac{perpendicular}{Base}[/tex]

In the triangle ABC, perpendicular (opposite side to [tex]\theta[/tex] ) is BC and base (Adjacent side) is AC

[tex]tan(\theta)=\frac{BC}{AC}[/tex]

[tex]\theta[/tex]=17.5 degree

AC=382100km

Putting the values, we get

[tex]tan(17.5)=\frac{BC}{382100}\\ \\BC=tan(17.5)*382100km\\\\BC=0.315*382100km\\\\BC=120475.66km[/tex]

Diameter=d=2*Radius

As BC is the distance from center of the sun, it is the radius, so we can find the diameter if we multiply it by 2.

Diameter of the sun=d=2*120475.66km

[tex]The\ diameter\ of\ the\ sun\ = 240951.33km[/tex]

Final answer:

To find the diameter of the Sun based on its angular diameter and distance from Earth, use the trigonometric function tan to calculate the true diameter, resulting in an approximate value of 865,373 miles.

Explanation:

To find the diameter of the Sun:

Given: Angular diameter = 0.5°, Distance from Earth = 93,000,000 milesCalculate the true diameter using the formula: True Diameter = 2 * Distance * tan(Angular diameter)Plug in the values: True Diameter = 2 * 93,000,000 * tan(0.5°)After calculation, the diameter of the Sun is approximately 865,373 miles.

The temperature is 71 °F at 2:00 in the afternoon. If the temperature drops 8 °F every hour after that, what is the temperature at 6:00 in the evening?

Answer = _____ F

Answers

Answer:

The answer is 39 degrees by 6:00 in the evening.

Step-by-step explanation:

Since it is 2:00 in the afternoon and there is 4 hours, with 8 degrees dropping every hour, 8 times 4 equals 32, so 71 degrees minus 32 degrees is 39 degrees.

Answer: the temperature at 6:00 in the evening is 39°F

Step-by-step explanation:

If the temperature drops 8 °F every hour after that, then the rate is linear and the rate at which the temperature is decreasing is in arithmetic progression. The formula for determining the nth term of an arithmetic sequence is expressed as

Tn = a + (n - 1)d

Where

a represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

From the information given,

a = 71 °F

d = - 8 °F (since it is decreasing)

n = 5 (2pm to 6pm)

We want to determine the value of the 5th term, T5. Therefore,

T5 = 71 - 8(5 - 1)

T5 = 71 - 32 = 39

Suppose the age of people in a certain population are distributed normally with a mean of 37.5 years and standard deviation of 6.2 years. What is the probability of randomly selecting a person who is over 45 years old given that they are older than 40.

Answers

Answer:

[tex] P(X>45 | X>40)= \frac{P(X>45 \cap X>40)}{P(X>40)}= \frac{P(X>45)}{P(X>40)}= \frac{0.113}{0.343}= 0.329[/tex]

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the age of a population, and for this case we know the distribution for X is given by:

[tex]X \sim N(37.5,6.2)[/tex]  

Where [tex]\mu=37.5[/tex] and [tex]\sigma=6.2[/tex]

We are interested on this probability:

[tex] P(X>45 | X>40)= \frac{P(X>45 \cap X>40)}{P(X>40)}= \frac{P(X>45)}{P(X>40)}[/tex]

We can begin finding [tex] P(X>40)[/tex] using the z score formula given by:

[tex] z = \frac{a-\mu}{\sigma}[/tex]

Using this formula we have:

[tex] P(X>40)= P(Z>\frac{40-37.5}{6.2}) = P(Z>0.403)[/tex]

And using the complement rule and the normal standard table or excel we have this:

[tex]P(Z>0.403)=1-P(Z<0.403)= 1-0.657= 0.343[/tex]

Now we can find [tex] P(X>45)[/tex] using the z score formula given by:

[tex] z = \frac{a-\mu}{\sigma}[/tex]

Using this formula we have:

[tex] P(X>45)= P(Z>\frac{45-37.5}{6.2}) = P(Z>1.210)[/tex]

And using the complement rule and the normal standard table or excel we have this:

[tex]P(Z>1.210)=1-P(Z<1.210)= 1-0.887= 0.113[/tex]

And replacing into our original probability we got:

[tex] P(X>45 | X>40)= \frac{P(X>45 \cap X>40)}{P(X>40)}= \frac{P(X>45)}{P(X>40)}= \frac{0.113}{0.343}= 0.329[/tex]

What is kinetic energy of emitted electron in photoelectroic effect?

The kinetic energy of emitted electron in photoelectric effect is given by

K = hc/λ - Φ where

h = Planck's constant = 6.63 × 10⁻³⁴ Jsc = speed of light = 3 × 10⁸ m/s λ = wavelength of light andΦ = work function of metal

Since a silicon (Φ = 7.77 × 10-19 J) surface is irradiated with UV radiation with a wavelength of 235 nm. Assume an electron was a mass of 9.11 x 10-31 kg. To determine the kinetic energy of the emitted electrons, we proceed as follows

Since the kinetic energy of the emitted electrons is

K = hc/λ - Φ

Given that

λ = 235 nm = 235 × 10⁻⁹ m andΦ = 7.77 × 10⁻¹⁹ J

So, substituting the values of the variables into the equation, we have that

K = hc/λ - Φ

K = (6.63 × 10⁻³⁴ Js × 3 × 10⁸ m/s)/235 × 10⁻⁹ m - 7.77 × 10⁻¹⁹ J

K = (19.89 × 10⁻²⁶ Jm)/235 × 10⁻⁹ m - 7.77 × 10⁻¹⁹ J

K = 0.0846 × 10⁻¹⁷ J - 7.77 × 10⁻¹⁹ J

K = 8.46 × 10⁻¹⁹ J - 7.77 × 10⁻¹⁹ J

K = 0.69 × 10⁻¹⁹ J

K = 6.9 × 10⁻²⁰ J

So, the kinetic energy is K = 6.9 × 10⁻²⁰ J

Answers

Answer:

The correct option: (2) Triangle ABC that has angle measures 45°, 45° and 90°.

Step-by-step explanation:

It is provided that a triangle ABC has an acute angle for which the sine and cosine ratios are equal to 1.

Let the acute angle be m∠A.

For the sine and cosine ratio of m∠A to be equal to 1, the value of Sine of m∠A should be same as value of Cosine of m∠A.

The above predicament is possible for only one acute angle, i.e. 45°, since the value of Sin 45° and Cos 45° is,  

                                 [tex]Sin\ 45^{o} =Cos\ 45^{o} = \frac{1}{\sqrt{2} }[/tex]

So for acute angle 45° the ratio of Sin 45° and Cos 45° is:

                                         [tex]\frac{Sin\ 45^{o}}{Cos\ 45^{o}} = \frac{\frac{1}{\sqrt{2} } }{\frac{1}{\sqrt{2} } } = 1[/tex]

Hence one of the angles of a triangle is, m∠A = 45°.

Comparing with the options provided the triangle is,

Triangle ABC that has angle measures 45°, 45° and 90°.

Thus, the provided triangle is a right angled isosceles triangle, since it has two similar angles.

Answers

Answer:

3

Step-by-step explanation:

the initial statement is  

y ∝ 1 /x

 to convert to an equation multiply by k the constant

of variation

y = k × 1 /x = k /x

to find k use the given condition

y = 5  when  x = 6

y = k/ x ⇒ k = y x = 5 × 6 = 30

y = 30 /x

when  

x = 10

then

y = 30 /10 = 3

Answer: y = 3

Step-by-step explanation:

In inverse variation, as one variable increases, the other variable decreases and as one variable decreases, the other increases.

We would introduce a constant of proportionality, k. Therefore,

y = k/x

When y = 5 , x = 6

Therefore,

5 = k/6

Cross multiplying by 6, it becomes

k = 6 × 5 = 30

The expression becomes

y = 30/x

Therefore, when x is 10,

y = 30/10

y = 3

Answers

Answer:

Step-by-step explanation:

We are given that

[tex]m_1=7 kg[/tex]

[tex]m_2=0.7 kg[/tex]

Total mass =[tex]m_1+m_2=7+0.7=7.7 Kg[/tex]

We have to find the magnitude of the normal force with which the bottom cube is acting on the top cube.

When both cube are fall freely then

g=[tex]0m/s^2[/tex]

Then, the weight=[tex]mg=7.7\times 0=0 N[/tex]

The direction of weight is downward.

We know that

Normal force is equal to weight and act in opposite direction of weight.

When the weight is zero N then

The magnitude of the normal force with which the bottom cube is acting on the top cube=0 N

For example, outcome HTH means coin 1 was heads, coin 2 was tails, coin 3 was heads. Note that there are 8 total outcomes, and we assume that each one is equally likely. What is the probability that the outcome has at least two consecutive heads in the sequence?

Answers

Answer: 3/8

Step-by-step explanation:

Firstly, let's look at the possible outcome when 3 coins are tossed.

If two coins are first tossed, the possible outcome will be,

{HH, HT, TH, TT}

if one more coin is tossed together with the two to make it 3coins, the possible outcome will be gotten by matching the H and T of the third coin with the set of sample space above to give us,

S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

This gives a total sample space of 8.

Outcomes that has at least two consecutive heads in the sequence are {HHH, HHT, THH} which is the possible outcome i.e 3

Probability that the outcome has at least two consecutive heads in the sequence will be;

Let V be a vector space and assume that T, U, W are sub spaces of V. Show that if T cup U W is a sub space of V, then two of these subspaces must be contained in the other one?

Answers

Answer: T⊂U⊂W are subspaces of V

Step-by-step explanation:

Proof: This is the easier direction.

If T⊂U⊂W or W⊂U⊂T then we have U⊂T⊂W = T or T⊂U⊂W = U

orT⊂U⊂W=W respectively.

SoT⊂U⊂W is a subspace as T, U and W are subspaces.

1st case :T⊂U⊂W is true Then the disjunction W⊂U⊂T or U⊂T⊂W is trivially true.

Let x∈W1 and y∈W2−W1.

By the definition of the union, we have x∈W∪T∪C and y∈T⊂U⊂W

As T∪U∪W is a subspace, x+y∈T∪C∪W which, again by the definition of the union, means that x+y∈W∪T∪C

V∈W∪T∪C

As V was arbitrary, as desired.

Final answer:

If T ∪ U ∪ W is a subspace of V, then two of the subspaces must be contained in the other one.

Explanation:

If T ∪ U ∪ W is a subspace of V, then two of the subspaces must be contained in the other one. We can prove this by contradiction. Assume that none of the subspaces is contained in the other. This means that there is an element in T that is not in U ∪ W, an element in U that is not in T ∪ W, and an element in W that is not in T ∪ U. If we take any two of these elements, one from each subspace, and add them together, the result will not be in T ∪ U ∪ W, which contradicts the assumption.

Therefore, two of the subspaces must be contained in the other one.

Peter answered 15 questions on a quiz and obtained 29 points. If 3 points were given for each correct answer and one point deducted for each wrong answer, how many questions did Peter answer correctly?

Answers

Final answer:

By setting up an equation with x representing the number of correct answers, we find that Peter answered 11 questions correctly on his quiz.

Explanation:

To determine how many questions Peter answered correctly on his quiz, we first need to set up an equation to represent the situation. Let's let x be the number of questions Peter got right, and since he answered 15 questions in total, it means he got (15 - x) questions wrong. Since he gets 3 points for each correct answer and loses 1 point for each wrong answer, we can write the equation as:

3x - (15 - x) = 29

Now, we will solve for x:

3x - 15 + x = 29

4x - 15 = 29

4x = 29 + 15

4x = 44

x = 44 / 4

x = 11

So, Peter answered 11 questions correctly.

what are the values of c and d in the matrix [[6,8],[-11,15]]-[[c+2,3],[-5,d-4]]=[[22,5],[-6,17]]

Answers

Answer:

c = -18

d = 2

Step-by-step explanation:

[[6,8],[-11,15]]-[[c+2,3],[-5,d-4]]=[[22,5],[-6,17]]

First we arrange the subtraction to clear the unknowns

- [[c+2,3],[-5,d-4]] = [[22,5],[-6,17]] - [[6,8],[-11,15]]

  [[c+2,3],[-5,d-4]] = [[6,8],[-11,15]]  - [[22,5],[-6,17]]

Now we solve what can be done

  [[c+2,3],[-5,d-4]] = [[6-22 , 8-5],[-11+6 , 15-17]]

  [[c+2,3],[-5,d-4]] = [[-16 , 3] , [-5 , -2]

we match each term with its corresponding one and we will obtain

c + 2 = -16             d - 4 = -2

c = -16 - 2              d = -2 + 4

c = -18                    d = 2

The cylinder coffee cup has a radius of 1.8 inches and a height of 4 inches. Find the surface area of the coffee cup, not including the handle. Round to the nearest tenth

Answers

Answer:

Step-by-step explanation:

The formula for determining the total surface area of a cylinder is expressed as

Total surface area = 2πr² + 2πrh

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

Assuming that the cylindrical cup is open at the top, the formula becomes

Area = πr² + 2πrh

From the information given,

Radius = 1.8 inches

Height = 4 inches

Therefore, the surface area of the coffee cup is

(3.14 × 1.8²) + (2 × 3.14 × 1.8 × 4)

= 10.1736 + 45.216

= 55.4 inches² to the nearest tenth.

Step-by-step explanation:

In a lilac paint mixture 40% of the mixture is white paint 20% is blue and the rest is red there are four cups of blue paint used in a batch of lilac paint how many cups of white paint is used

Answers

Answer: 8 cups of white paint is used.

Step-by-step explanation:

In a lilac paint mixture 40% of the mixture is white paint 20% is blue and the rest is red. This means that the percentage of red paint in the mixture is 100 - (40 + 20) = 40%

There are four cups of blue paint used in a batch of lilac paint. This means that 20% of the total number of cups of paint used in a batch of lilac paint is 4.

Assuming that the total number of cups of paint in the mixture is x, then,

20/100 × x = 4

0.2x = 4

x = 4/0.2 = 20

Therefore, the number of cups of white paint used is

40/100 × 20 = 0.4 × 20

= 8 cups

Final answer:

In the lilac paint mixture, for every 4 cups of blue paint, which accounts for 20% of the mixture, there are 8 cups of white paint, corresponding to 40% of the mixture.

Explanation:

The question involves determining the amount of white paint used in a batch of lilac paint given that 40% of the paint mixture is white, 20% is blue, and the remainder is red. We're told that 4 cups of blue paint are used. Since blue paint represents 20% of the mixture, we can use this information to find out the total amount of the paint mixture and then calculate the amount of white paint needed.

First, find the total amount of the paint mixture by calculating the full 100% that the 4 cups of blue paint (20%) contribute to. This calculation is as follows:

Total Paint = 4 cups (20%) / 0.20Total Paint = 20 cups

Now that we know the total paint mixture is 20 cups, we can determine the amount of white paint, which is 40% of the total mixture:

White Paint = Total Paint x 40%White Paint = 20 cups x 0.40White Paint = 8 cups

Therefore, 8 cups of white paint are used in the mixture.
