What is one whole and three fourths plus five sixths plus one whole and one fourth

The answer is W, just took the test.

Step-by-step explanation:

As the distance from the equator to the north pole is almost 10,000 km.

As we know that

As the planet Earth is outspread or widest at its Equator and the distance around the Earth at the Equator - its circumference - is [tex]24,901\:miles[/tex].

[tex]24,901\:miles\:=\:40,075\:kilometers[/tex]

So, the distance around the Earth at the Equator - its circumference - is [tex]40,075\:kilometers[/tex].

Also, at the equator, [tex]1^{0}[/tex] ( [tex]1\:degree[/tex] ) of longitude and latitude both cover about [tex]111[/tex] km, or just under [tex]70[/tex] miles.

Answer:

(8,8)

Step-by-step explanation:

The image point of (3,7) after translation 5 units to the right and 1 unit up is (8,8).

Translation of a point in a coordinate plane involves moving the point to a new location without changing its orientation or size.

To find the image of a point (3,7) after a translation of 5 units to the right and 1 unit up, we simply add the translation amounts to the original coordinates.

For a rightward movement, we add 5 to the x-coordinate, and for an upward movement, we add 1 to the y-coordinate.

Therefore, the new position of the point after translation will be:

So, the image point after the translation is (8,8).

Answer:

58 and 42.

Step-by-step explanation:

Let the 2 numbers be x and 100-x.

Also let x be the largest number, so

x ≥ 100 - x + 16     ( 'At least 16' means equal to 16 or greater than 16).

Add in x to both sides:

x + x  ≥ 100 + 16

2x ≥ 116

x ≥ 58.

But since the sum of the 2 numbers is 100,  x must be 58 and the other number is 42.

Answer:

y = (1/12)*x + 7/4

Step-by-step explanation:

y=−12x−1

Perpendicular line:

y = a*x + b

y = (1/12)*x + b

2 = (1/12) * 3 + b

2 = (3/12) + b

2 = 1/4 + b

2 - 1/4 = b

7/4 = b

Perpendicular line:

y = (1/12)*x + 7/4

Step-by-step explanation:

Answer:

Step-by-step explanation:

7/9x + 2 = 5/6.....multiply by the common denominator of 18

14x + 36 = 15 <=== re-written without fractions

14x = 15 - 36

14x = -21

x = -21/14

x = - 3/2...(or - 1 1/2)...ur solution

To rewrite the equation 7/9x + 2 = 5/6 without fractions, we multiply every term by the least common denominator (18) to get 14x + 36 = 15. Subtracting 36 from both sides and solving for x results in x = -21/14.

In order to rewrite the equation without fractions, we can eliminate the fractions by finding the least common denominator (LCD) and multiplying every term in the equation by it.

Answer:

B) y = x + 2 and y = -x - 4

Step-by-step explanation:

The equation of a line is represented with y = mx + b.

"x" and "y", when substituted, tell you if a point (x, y) is on the line.

"m" is slope, and tells if it goes up (positive slope) or down (negative)

"b" is the y-intercept, when the line hits the y-axis.

In the graph, we have two lines. One goes upwards (read from left to right), and the other goes downwards.

The graph that goes upwards hits the y-axis at positive "2".

The graph that goes downwards hits the y-axis at (negative) "-4".

Since the choices only have positive 1 or negative 1 as the slope, we only have to worry if it goes up or down.

Take the key information, slope and y-intercept, to write the equations.

"upwards slope, y-axis at 2"

y = x + 2

"downwards slope, y-axis at -4"

y = -x - 4

Answer:

43.65  grams of bird feed containing 5% seed must be added to get bird feed that is 40% seed

Step-by-step explanation:

Let us assume the total capacity of the container  = m grams

Here, given: 80% of m = 100 grams

[tex]\implies \frac{80}{100} \times m = 100\\\implies m = \frac{100 \times 100}{80} = 125[/tex]

or, the TOTAL CAPACITY of container  = 125 grams

Now, the container already has 5 % seeds.

Calculating 5% of the capacity, we get:

[tex]\implies \frac{5}{100} \times 125 = 6.25[/tex]

So, the container already has 6.25 grams.

Now, the total filling of the container should be 40%.

Calculating 40% of the capacity, we get:

[tex]\implies \frac{40}{100} \times 125 = 50[/tex]

So, the weight of seeds that NEEDS To be in total  = 50 grams.

Also, it already has  6.35 grams.

So, the weight of seeds to be added  = 50 grams - 6.35 grams

                                                                   = 43.65 grams

Hence, 43.65  grams of bird feed containing 5% seed must be added to get bird feed that is 40% seed.

43.75  grams of bird feed containing 5% seed must be added to get bird feed that is 40% seed  

Percentage is a number or ratio that can be expressed as a fraction of 100.

Let the total mass of the container = x

Therefore,

80% of x = 100g of bird feed

80 / 100 × x = 100

80x = 10000

x = 10000 / 80

x = 125 grams

Therefore, 5% volume will be as follows;

Therefore, 40% volume is as follows:

Answer:

Therefore,

The Dimensions are,

[tex]Length = 34\ cm\\\\Width = 9\ cm[/tex]

Step-by-step explanation:

Given:

Perimeter of a rectangle,

Perimeter = 86 cm

let "x" be the width of rectangle,

Width = x

then according to the given condition,

length will be given as,

[tex]Length = 3x+7[/tex]

To Find:

Length =?

Width =?

Solution:

Perimeter of rectangle is given by,

[tex]\textrm{Perimeter of Rectangle}=2(Length+Width)[/tex]

Substituting the values we get

[tex]86=2(3x+7+x)\\\\86=2(4x+7).........Equation\\\\86=8x+14\\\\8x=86-14=72\\\\x=\dfrac{72}{8}=9\ cm[/tex]

Substituting "x" in Length we get

[tex]Length = 3\times 9 +7=34[/tex]

Also Area Of Rectangle is given by

[tex]\textrm{Areaof Rectangle}=(Length\times Width)=34\times 9=306\ cm^{2}[/tex]

Therefore,

The Dimensions are,

[tex]Length = 34\ cm\\\\Width = 9\ cm[/tex]

Final answer:

The dimensions of the rectangle with an area of 306 cm squared and a perimeter of 86 cm, where the length is 7 more than three times the width, are 9 cm by 34 cm.

Explanation:

To solve for the dimensions of the rectangle with an area of 306 cm squared and a perimeter of 86 cm, where the length (L) is 7 more than three times the width (W), we will set up a system of equations. First, express the given relationships:

Perimeter (P) = 2W + 2L = 86 cm

Area (A) = W * L = 306 cm squared

L = 3W + 7

Next, substitute the expression for L into the perimeter equation:

2W + 2(3W + 7) = 86

2W + 6W + 14 = 86

8W + 14 = 86

8W = 72

W = 9 cm

Now, plug the value of W back into the equation for L:

L = 3(9) + 7 = 34 cm

Thus, the dimensions of the rectangle are 9 cm by 34 cm.

Answer:

Step-by-step explanation:

student teacher ratio of 5:2....added = 7

so students make up 5/7 of the total people and teachers make up 2/7 of the total people.

Last year.....56 people

students : 5/7 * 56 = 280/7 = 40 students

teachers : 2/7 * 56 = 112/7 = 16 teachers

this year....70 total people

students : 5/7 * 70 = 350/7 = 50 students

teachers : 2/7 * 70 = 140/7 = 20 teachers

Final answer:

To find the number of students and teachers based on their ratio and total count, we applied the ratio of 5:2 to the total counts of 56 and 70 for the last year and this year, respectively. This calculation revealed there were 40 students and 16 teachers last year, and 50 students and 20 teachers this year.

Explanation:

The student has asked about finding the number of students and teachers at a preschool in two different years based on a given student-to-teacher ratio and the total count of students and teachers for those years.

Step-by-Step Solution:

First, understand the ratio of students to teachers is 5:2. This means for every 5 students, there are 2 teachers.

To solve for last year, we have a total of 56 individuals (students and teachers). Let's represent students as 5x and teachers as 2x, given their ratio. Therefore, 5x + 2x = 56, solving this gives us x = 8. This means there were 40 students (5*8) and 16 teachers (2*8) last year.

For this year, we have a total of 70 individuals. Using the same method, 5x + 2x = 70, we find that x = 10. This means there are 50 students (5*10) and 20 teachers (2*10) this year.

By understanding and applying the concept of ratios, we were able to find the number of students and teachers for both years.

Answer:

Infinitely many solutions

Step-by-step explanation:

If we have a system of equation like:

2x+y=4

6x+3y=12

If we make y the subject in the first equation and substitute into the second equation, we get:

6x+3(4-2x)=12

We expand to get:

6x+12-6x=12

6x-6x+12=12

Now the variable adds out to give:

12=12

This statement is true so the equation has infinitely many solution.

Answer:

Explanation:

When the variable adds out means that after all the simplifications, at the end, it will not appear in the final sentence or expression.

Then, if the final sentence is true, and not variable appears, but only constants, the sentence is always true, no matter what value the variable takes.

That means that you can put any value for the variable in the original equation and the equation will be true; hence there are infinite solutions.

This is an example:

1. Equation:

2. Remove the parenthesis:

3. Add like terms on the right side and transpose the variables to the left side:

4. Combine like terms on the left side:

Thus, the variable added out and the final sentence is true. Hence, this equation has infinite solutions, which you can prove substituting the variable with any value.

Answer:

(4,3)

Step-by-step explanation:

The orthocenter of a triangle is the point of intersection of the altitudes of the triangle .

The vertices are:

A(-2,5), B(6,5), and C(4,-1)

Slope of (6,5), and (4,-1) is

[tex]m = \frac{5 - - 1}{6 - 4} = 3[/tex]

Slope of altitude through A is

[tex] - \frac{1}{3} [/tex]

The equation of the altitude through A is

[tex]y - 5 = - \frac{1}{3} (x - - 2)[/tex]

[tex]y = - \frac{1}{3} x + \frac{13}{3} [/tex]

The slope of A(-2,5), B(6,5) is zero because it is a horizontal line.

The equation of altitude through (4,-1) will be the vertical line x=4.

This implies that,

[tex]y = - \frac{4}{3} + \frac{13}{3} = 3[/tex]

Hence the orthocenter is (4,3)

The total number of blue cards in the game = 48

Step-by-step explanation:

Total number of blue and yellow cards = 84

let the blue card denote B and yellow card as Y

B = 4

Y = 3

Total number of cards in one round = 7

number of rounds possible = total number of cards / number of cards in one round

= 84/7

= 12

number of blue cards = 12 x 4

= 48

  The total number of blue cards in the game = 48

Step-by-step explanation:

a) Probability of both being males is 27%

b) Probability of both being females is 23%

c) Probability of having exactly one male and one female is 50%

Step-by-step explanation:

a)

The probability that the birth is a male can be written as

[tex]p(m) = 0.52[/tex] (which corresponds to 52%)

While the probability that the birth is a female can be written as

[tex]p(f) = 0.48[/tex] (which corresponds to 48%)

Here we want to calculate the probability that over  2 births, both are male. Since the two births are two independent events (the probability of the 2nd to be a male  does not depend on the fact that the 1st one is a male), then the probability of both being males is given by the product of the individual probabilities:

[tex]p(mm)=p(m)\cdot p(m)[/tex]

And substituting, we find

[tex]p(mm)=0.52\cdot 0.52 = 0.27[/tex]

So, 27%.

b)

In this case, we want to find the probability that both children are female, so the probability

[tex]p(ff)[/tex]

As in the previous case, the probability of the 2nd child to be a female is independent from whether the 1st one is a male or a female: therefore, we can apply the rule for independent events, and this means that the probability that both children are females is the product of the individual probability of a child being a female:

[tex]p(ff)=p(f)\cdot p(f)[/tex]

And substituting

[tex]p(f)=0.48[/tex]

We find:

[tex]p(ff)=0.48\cdot 0.48=0.23[/tex]

Which means 23%.

c)

In this case, we want to find the probability they have exactly one male and exactly one female child. This is given by the sum of two probabilities:

- The probability that 1st child is a male and 2nd child is a female, namely [tex]p(mf)[/tex]

- The probability that 1st child is a female and 2nd child is a male, namely [tex]p(fm)[/tex]

So, this probability is

[tex]p(mf Ufm)=p(mf)+p(fm)[/tex]

We have:

[tex]p(mf)=p(m)\cdot p(f)=0.52\cdot 0.48=0.25[/tex]

[tex]p(fm)=p(f)\cdot p(m)=0.48\cdot 0.52=0.25[/tex]

Therefore, this probability is

[tex]p(mfUfm)=0.25+0.25=0.50[/tex]

So, 50%.

Answer:

Trafton will need to pay $ 900 in addition to what is in his savings account, to buy the used car he wants.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Initial deposit = $ 7,000

Annual interest = 6.5% = 0.065 compounded continuously

Time of the investment = 4 years

Price of the used car Trafton wants to buy = $ 10,000

2. How much money will he need to pay in addition to what is in his savings account?

1. For answering the question, let's calculate how much money Trafton has in his savings account after 4 years, this way:

FV = PV * e ^ (i * t)

Where,

FV = Future value of the initial deposit after t time

PV = Initial deposit

e = Euler's number (2.7183)

i = 0.065 compounded continuously

t = 4 years

Replacing with the real values, we have:

FV = 7,000 * 2.7183^(0.065 * 4)

FV = 7,000 * 1.30 (Rounding to the nearest hundredth)

FV = $ 9,100

Now, we can elaborate how much money will Trafton need to pay in addition, as follows:

Money in addition = Price of the used car Trafton wants to buy - Future Value of the savings account after 4 years

Money in addition = 10,000 - 9,100

Money in addition = $ 900

Trafton will need to pay $ 900 in addition to what is in his savings account, to buy the used car he wants.
