ABCD∼EFGH AD=45 in. , EH=75 in. , and AB=30 in. What is EF ? Enter your answer in the box. EF = in.

Answers

Answer 1

The ~ symbol means that the 2 shapes are similar, meaning the same shape but not the same size.

To determine the measure of side length EF, you must find the relationship between the 2 side lengths.

You should set these up as ratios of the length to the width. So, for ABCD, it is 30/45. Make this equal to x/75. If you simplify the first ratio to 2:3, you can then multiply by both numerator and denominator by 25 to get x = 25 in/ 75 in.

Another way is to use cross products with you proportion. 75 x 30 = 45x. Solve for x to get 50 inches.

That triangular area is not carpeted, so the carpet area is
  72 ft^2 -9 ft^2 = 63 ft^2.

How does the height of the triangle compare to the height of the rectangle

Answers

The triangle's height must be 3 times that of the rectangle for the areas to be the same.

For a triangle, A = (1/3)bh
For a rectangle, A = bh

If we let h represent the height of the rectangle and H represent the height of the triangle, we have

Which statements are true? Select each correct answer. A To estimate the percentage well, she would need to collect data for all 35,000 families. B Since her sample was randomly selected, she can reasonably infer that about 45% of the 35,000 families in her town own at least one computer. C If she collected data for a random sample of 1000 families in her home town, then that percentage would be a better estimate for the percentage of all 35,000 families that own a computer.

You are buying salsa at the grocery store. You have a manufacturer’s coupon for $0.50 off and the store is offering 50% off if you buy 2 containers. One container of salsa costs $3.25. What is your final cost?

Answers

3.25*2 = 6.5*0.5 = 3.25-0.50 = $2.75

Answer: Final cost will be $2.75.

Step-by-step explanation:

Since we have given that

Cost of salsa container = $3.25

Off on coupon = $0.50

Final cost of one salsa container is given by

[tex]3.25-0.50\\\\=\$2.75[/tex]

Hence, the final cost will be $2.75.

if he bought two containers

Cost of two containers is given by

[tex]3.25\times 2\\\\=\$6.50[/tex]

Coupon 50% off is given by

[tex]6.50\times 0.5\\\\=3.25[/tex]

So, Final cost is given by

[tex]6.25-3.25-0.5\\\\=\$2.75[/tex]

Hence, Final cost will be $2.75.

A line containing the points (2, 16) and (-8, -4) intersects the y-axis at what point?

Answers

We first need to find the slope of this line: (-4-16)/(-8-2) = -20/-10 = 2.
We write this as slope-intercept: y = 2x + b(b is the y-intercept). Now we plug in on of the above points: 16 = 2(2) + b, and b is equal to 12.
---
Hope this helps!

Final answer:

To find the y-intercept of a line, we can use the equation y = mx + b. By substituting the coordinates of one of the given points into the equation, we can solve for b and find the y-intercept. The y-intercept is the point where the line intersects the y-axis.

Explanation:

The line containing the points (2, 16) and (-8, -4) can be represented by the equation y = mx + b, where m is the slope and b is the y-intercept. To find the y-intercept, we need to substitute the values of one of the given points into the equation and solve for b.

Using the point (2, 16), we have 16 = m(2) + b. Substituting the values of the other point gives us -4 = m(-8) + b. We can solve this system of equations to find the values of m and b.

16 = 2m + b-4 = -8m + b

By subtracting equation 2 from equation 1, we can eliminate b and solve for m. After finding the value of m, we can substitute it back into either equation to find the value of b. This will give us the y-intercept.

Once we have the values of m and b, we can write the equation of the line in the form y = mx + b. The y-intercept will be the point at which the line intersects the y-axis.

The approximate volume of Sandra's pitcher is 904.78 cubic inches.

What is the volume of a right circular cylinder?

Suppose that the radius of considered right circular cylinder be 'r' units.

And let its height be 'h' units.

Then, its volume is given as:

[tex]V = \pi r^2 h \: \rm unit^3[/tex]

Right circular cylinder is the cylinder in which the line joining center of top circle of the cylinder to the center of the base circle of the cylinder is perpendicular to the surface of its base, and to the top.

We are given that;

For Larry's picture, we have r = 4 inches and h = 13 inches. Substituting these values into the formula, we get:

V = π(4^2)(13)

V ≈ 804.25 cubic inches

Therefore, the approximate volume of Larry's picture is 804.25 cubic inches.

For Sandra's pitcher, we have r = 6 inches and h = 8 inches. Substituting these values into the formula, we get:

V = π(6^2)(8)

V ≈ 904.78 cubic inches

Therefore, the volume of cylinder will be 904.78 cubic inches.

In the past you paid $800
per month to rent your apartment. You now pay $900
per month for your rent. What is the percent increase in your rent?

Answers

Hello! $800 was the past amount for rent and now it's $900. 900 - 800 is 100. that's a $100 difference. In order to find the percent increase in the rent, we can write and sovle a proportion. It would be set up as change/original = x/100, where change is difference between two numbers and original is the previous price. It would be set up like this:

100/800 = x/100

Let's crossmultiply the values. 100 * 100 is 10,000. 800 * x is 800x. That makes 10,000 = 800x. Now, divide each side by 800 to isolate the x. 800x/800 cancels out. 10,000/800 is 12.5 or 12.5%. Let's check this by multiplying by 112.5%. 800 * 112.5% (1.125) is 900. That's what we're looking for! There. x = 12.5%. The percent increase is 12.5%.
