Answers

Answer 1
Answer:4y

Answers

Answer:

Step-by-step explanation:

First we have to find their hourly rate. We do this by dividing their total over 4 hours by 4 to get over just 1 hour.

210 / 15 = 14

I would take 14 hours to earn $210.

Find the missing right triangle side lengths in the models of the Pythagorean Theorem below

Answers

Answer: 24, 10, 26 and 4.6, 5, 6.7

Step-by-step explanation: for the first triangle the square with the area 576 has side lengths of 24 because 24 is the square root of 576, the square with the area 676 has a side length of 26 because 26 is the square root of 576, and we already know the side lengths of the third triangle are 10 for the second triange we know the side length of the square with the area 21 is about 4.6 because √21 ≈ 4.6 and the square with the area 25 the side length is 5 because √25 = 5 and the last square the side length is 6.7 because √46 ≈ 6.7
