Answer:

A. 5

Step-by-step explanation:

use pythagorean theorem: a^2 + b^2 = c^2

but since we are finding the value of A; we'll use a= (square root) c^2 - b^2

A= 13^2- 12^2

A= 169 - 144

A= 25

A= 5 ( because we square root 25)

Scott washed cars for 2 1/2 hours as a fundraiser. It took him 1/4 hour to wash one car. How many cars did Scott wash

lana66690 [7]

Answer:

He washed 10 cars.

Step-by-step explanation:

To make this easier covert 1/2hours into 1/4 hours. 2 1/2 = 4/2+1/2 = 5/2. Now take 5/2 and make it 1/4th's, 5/2 = 10/4. It takes 1/4 hours to wash one car so, 10/4 divided by 1/4. Don't divide fractions so, 10/4 x 4/1, we switch the second number around to get 40/4. Now we can simplify, 40/4 = 10.
