A Right Triangle (ABC) has sides measuring 3 inches and 4 inches. The hypotenuse is 5 inches. A similar right triangle (A'B'C') is created with sides of 7.5 and 10. What is the length of the hypotenuse? (Show all work)

Answers

Answer 1
Answer:

Answer:

The length of hypotenuse is 12.5

Step-by-step explanation:

First 7.5 x 7.5 = 56.25

Then 10 x 10 = 100

Add them together 56.25 + 100 = 156.25

Then square root 156.25 and you get 12.5
Answer 2
Answer:

Answer:

12.5 in.

Step-by-step explanation:

You could use the pythagorean theorem, or you can use scale factor. The scale factor between side A and A' is 7.5/3=2.5, which is your scale factor. Multiplying 2.5 by your original hypotenuse gives you 12.5

The partial products are-
42 * 28 = (40 + 2)*(20 + 8) = 40*20 + 40*8 + 2*20 + 2*8 
= 800 + 320 + 40 + 16

How do you factor 8x+56?

Answers

If you mean how do you get x by it's you divide both sides by 8, to cancel out the multiplication between x and 8, meaning that it would end up being x=7, sorry if that didn't answer your question correctly. 
Divide 56 by eight (=7)
Divide 8x by eight (=X)
So you have X + 7
So I think it would be 1(x+7)

cant really see the first one, but the second one is correct.

at t=0;
h=-16(0)+40(0)+3
h=3
therefore the initial height is 3 feet, you are correct.

Which strategies can be used to solve this problem? Kathleen invited 28 people to her party. She plans to seat 8 people at the dining room table. She will put the rest at round tables with 4 people at each table. What is the fewest number of round tables that Kathleen needs so that each guest will have a seat? Choose all answers that are correct. A. Draw a diagram. Eight people at 1 table, 4 people at round table, 4 people at round table, 4 people at round table, 4 people at round table, 4 people at round table. Count the number of round tables. B. Use logical reasoning. Start with 28 people, subtract 8 people who will sit at the dining room table, that leaves 20 people. Keep subtracting 4 people until you get to 0. Count how many times you subtracted 4 people. C. Translate into an equation. 28 – 8 + 4 + 4 = t D. Work backward. There are 28 people coming to the party. There is one dining table, so subtract 1. Now figure out how many round tables there are and subtract that number.

Answers

I'm guessing A because 28-8=20 and 20/4=5 round tables needed
