m<7=65

m<4 = 115

m<6 = 115

m<1=65

m<16 = 60

m<18 = 60

m<21 = 120

m<10 = 55

m<11 = 125

m<12 = 55

Step-by-step explanation:

(1) m<7 = 65° (corresponding angles are equal)

(2) m<4 = 180 - 65 = 115 (angles on a straight line)

(3) m<6 = 115 (angles on a straight line)

(4) m<1 = 180-115 = 65

(5) m<16 = 180 - 120 = 60°

(6) m<18 = m<14 = 60°(corresponding angles are equal)

(7) m<21 = 180 - 60 = 120

(8) m<10 = m<12 = 180-(65+60)=55(sum of angles in a triangle)

m<10 = 55°

Final answer:

To find the intersection points of the paths of two particles, one needs to set their position functions equal and solve for the variable t. If no solution exists, then the intersection points do not exist, and the answer is DNE.

Explanation:

To find the points where the paths of two particles intersect, we set their respective position functions r1(t) and r2(t) equal to each other and solve for t. The position functions given are:
r1(t) = (t, t^2, t^3)
r2(t) = (1 + 4t, 1 + 16t, 1 + 52t).

Their paths intersect when:
x1 = x2
y1 = y2
z1 = z2.

By solving these equations, we find the common t values that make both position vectors equal. If there is no common t that satisfies all three conditions, then the particles never collide, and the answer is DNE (Does Not Exist).

Step-by-step explanation:

To find the solution, Tanisha can graph each side of the equation as its own function:

y₁ = log₃(5x)

y₂ = log₅(2x + 8)

The solution is where the two curves cross.  From the graph, that happens at x ≈ 0.957.

Answer:

Step-by-step explanation:

Variability refers to the degree in which a set of data set spreads out or dispersed or clustered together. There are four measure of variability namely: range, interquartile range (IQR) variance and standard deviation. The consequence of increasing variability is that the distance from one score to another tends to increase, and a single score tends to provide a less accurate representation of the entire distribution.

In the context of a data set, increasing variability implies that scores in the dataset are dispersing more, increasing the distance from one score to another. Therefore, a single score provides a less accurate reflection of the entire distribution. The correct answer to the question is B.

The subject of the question relates to the concept of variability in a data set, which is a measure of how much scores differ from each other in a distribution. The question asks about the consequences of increasing variability.

If variability increases, it means that the scores in the dataset are spreading out more. In other words, the distance from one score to another tends to increase. Consequently, a single score tends to provide a less accurate representation of the entire distribution because the scores are more spread out and there is a higher level of diversity in the scores. So, the correct answer is B.

Answer:

Length of bases of the trapezoid are 5 inch and 15 inch.

Step-by-step explanation:

Let the length of the second base be 'x'.

Given:

one base of a trapezoid is 3 times the length of the second base.

So we can say that;

Length of the first base = [tex]3x[/tex]

Also Given:

the height of the trapezoid is 2 in smaller than the second base

So we can say that;

Height of the trapezoid = [tex]x-2[/tex]

Area of the trapezoid = 30

We need to find the length of both the bases.

Solution:

Now we know that;

Area of trapezoid is equal to half of the sum of the length of two bases multiplied by height of the trapezoid.

framing in equation form we get;

[tex]\frac{x+3x}{2}\times(x-2)=30\\\\\frac{4x}{2}\times (x-2)=30\\\\2x(x-2)=30[/tex]

Now Dividing both side by 2 we get;

[tex]\frac{2x}{2}(x-2)=\frac{30}{2}\\\\x(x-2)=15\\\\x^2-2x-15=0[/tex]

Now we will find the roots by factorizing the equation we get;

[tex]x^2-5x+3x-15=0\\\\x(x-5)+3(x-5)=0\\\\(x+3)(x-5)=0[/tex]

Now we find the values of x by solving separately we get;

[tex]x+3=0 \ \ \ \ Or \ \ \ \ \ \ x-5=0\\\\x=-3 \ \ \ \ \ \ \ Or \ \ \ \ \ \ x=5[/tex]

Now we have got 2 values of 'x' one positive and one negative.

Now we know that length of the base of trapezoid cannot be negative hence we will discard it and consider the positive value of 'x'.

Length of second base = 5 in

Length of first base = [tex]3x=3\times5 =15\ in[/tex]

Hence Length of base of the trapezoid are 5 inch and 15 inch.

Answer:

What am I suppose to do?

Step-by-step explanation:

Answer:Jason is 5 years old.

John is 4 years old.

Jackson is 12 years old.

Step-by-step explanation:

Let x represent the age of Jason.

Let y represent the age of John.

Let z represent the age of Jackson.

The ages of three siblings Jason John and Jackson totals 21 years. It means that

x + y + z = 21 - - - - - - - - - - -1

Jason is one year older than John. It means that

x = y + 1

Jackson is three times as old as John. It means that

z = 3y

Substituting x = y + 1 and z = 3y into equation 1, it becomes

y + 1 + y + 3y = 21

5y = 21 - 1 = 20

y = 20/5 = 4

x = y + 1 = 4 + 1

x = 5

z = 3y = 3 × 4

z = 12

Answer:

The container can hold 24 gallons of water.

Step-by-step explanation:

Let the Amount of water in gallons container can hold be 'x'.

Now given:

the container that holds the water for the football team is  1/4 full.

therefore Amount of water in container = [tex]\frac14x[/tex]

We need to find the Amount of water in gallons container can hold.

Solution:

Now given:

after pouring in 10 gallons of water, it is 2/3 full.

So equation can be framed as;

[tex]\frac14x+10=\frac23x[/tex]

Now Combining the like terms we get;

[tex]10=\frac23x-\frac14x[/tex]

Now We will use LCM to make the denominator common we get;

[tex]10=\frac{2x\times4}{3\times4}-\frac{1x\times3}{4\times3}\\\\10=\frac{8x}{12}-\frac{3x}{12}[/tex]

Now the denominators are common so we will solve the numerator we get;

[tex]10=\frac{8x-3x}{12}\\\\10=\frac{5x}{12}[/tex]

Now Multiplying both side by [tex]\frac{8}{12}[/tex] we get;

[tex]10\times\frac{12}{5}=\frac{5x}{12}\times \frac{12}{5}\\\\x=24 \ gallons[/tex]

Hence The container can hold 24 gallons of water.

Step-by-step explanation:

The distance of a point [tex](x_0,y_0)[/tex] from the y-axis can be written as

[tex]d_y = |x_0|[/tex]

because the x-coordinate of the y-axis is zero.

Similarly, the distance of a point [tex](x_0,y_0)[/tex] from the x-axis can be written as

[tex]d_x=|y_0|[/tex]

Since the y-coordinate of the x-axis is zero.

In this problem:

- The distance of the point A (−30, −45) from the y-axis can be written as

[tex]d_A = |-30|=30[/tex]

- The distance of point B (a,a) from the x-axis can be written as

[tex]d_B = |a| = a[/tex]

Since [tex]a>0[/tex].

We are told that 2/3 of the distance from the y-axis to point A (−30, −45) is equal to 1/4 of the distance from the x-axis to point B(a, a), which means

[tex]\frac{2}{3}d_A = \frac{1}{4}d_B[/tex]

Therefore,

[tex]\frac{2}{3}(30)=\frac{1}{4}a[/tex]

Let x represent the cost of one night at the hotel.

Let y represent the cost of renting the car for one day.

Connor went to New York for vacation. He spent 3 nights at a hotel and rented a car for 4 days. If Connor paid $675, it means that

3x + 4y = 675 - - - - - - - - - - - 1

Jillian stayed at the same hotel, but spent 4 nights and rented a car for 5 days from the same company. If Jillian paid $875, It means that

4x + 5y = 875 - - - - - - - - - - - -2

Multiplying equation 1 by 4 and equation 2 by 3, it becomes

12x + 16y = 2700

12x + 15y = 2625

Subtracting, it becomes

y = 75

Substituting y = 75 into equation 1, it becomes

3x + 4 × 75 = 675

3x + 300 = 675

3x = 675 - 300 = 375

x = 375/3 = $125

The total area of the rectangle is found by counting the total number of 1 cm squares inside the rectangle.

Note: This question is missing some details.

A more complete question is this: Use a ruler to measure the side lengths of the rectangle in centimeters. Mark each centimeter with a point and connect the points to show the square units. Then, count the squares you drew to find the total area.

Step-by-step explanation:

This method is used to determine area of a rectangle by counting the square unit inside the given rectangle.

For example, if the measurement of the sides of the rectangle is 8 cm and 5 cm respectively. To find the area;

Step 1: Mark out 1 cm points on each side of the rectangle.

Step 2: Connect each of the points.

Step 3: Count the number  1 cm squares within the triangle. The total number of squares gives the area of the triangle.

In this example, the number of 1 cm squares will be found to be 40. So the area of the rectangle is 40 cm squares or 40 cm².

Answer: [tex]H'(4,-3)[/tex]

Step-by-step explanation:

For this exercise you must remember that the original figure (before a transformation) is called "Pre-Image" and the one obtained after the transformation is called "Image".

 A Translation is defined as a transformation in which the figure is moved a  fixed distance in a fixed direction. In this kind of transformatiosn the size and shape do not change and the figure is not flipped.

In this case you know that the Pre-Image is the Triangle FGH.

You can identify in the picture that its vertex H has these coordinates:

[tex]H(1,-2)[/tex]

Where:

[tex]x=1\\y=-2[/tex]

Since the rule is:

[tex](x,y)[/tex] → [tex](x+3,y-1)[/tex]

You can substitute the coordinates of H into the given rule in order to find the coordinates of H'. This is:

[tex]H'=(1+3,-2-1)=(4,-3)[/tex]

The coordinates of H after translation using the rule (x,y) > (x+3,y-1) are obtained by adding 3 to the x-coordinate and subtracting 1 from the y-coordinate of H's original position.

To determine the coordinates of H after applying the translation rule (x,y) > (x+3,y-1), you have to add 3 to the x-coordinate and subtract 1 from the y-coordinate of point H's original position.

For example, if H originally has coordinates (a,b), then after the translation, the new coordinates of H will be (a+3, b-1).

The given translation rule does not change regardless of the element being translated, be it point or vector, as the rule is applied to each coordinate independently.

Therefore, if you know the original coordinates of point H, you just apply the rule directly to find the translated coordinates.

The solution is: : $117,783.05 will be her balloon payment at the end of 7 years if she chooses this mortgage.

Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.

here, we have,

Step 1

Calculate the number of monthly payments for 7 years.

The formula we would be using is given as:

Monthly payment = [Loan amount × (rate/number of year)] ÷ [1 - (1 +r/n)^nt)]

Loan amount =$146,000

Rate = 4.75% = 0.0475

n = number of payments = 12

t= number of years = 23

Monthly payment = [ 146,000× (0.0475/12)] ÷ [1 - (1 +0.0475/12)^-276)]

Monthly payment = $870.49

Step 2

Calculate the amount left after 7 years using the formula

Ballon payment after 7 years = Loan amount ( 1 + r)ⁿ - P[(1 +r)ⁿ - 1 /r]

r = 4.75% for 12 years

= 146,000( 1 + 0.0475/12)^84 - 870.49[((1 + 0.0475/12)^84 - 1)/0.0475/12]

= $117,783.05

Answer: the maximum length of the sandbox is 42 feet.

the maximum width of the sandbox is 16 feet.

Step-by-step explanation:

Let L represent the length of the sandbox.

Let W represent the width of the sandbox.

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

The perimeter of the sandbox must be less than or equal to 116 feet. This means that

2(L + W) ≤ 116

Dividing through by 2, it becomes

L + W ≤ 116/2

L + W ≤ 58 - - - - - - - - -1

The length of the sandbox will be 6 less than 3 times the width. This means that

L = 3W - 6

Substituting L = 3W - 6 into equation 1, it becomes

3W - 6 + W ≤ 58

4W ≤ 58 + 6

4W ≤ 64

W ≤ 64/4

W ≤ 16
