Answer:
498
Step-by-step explanation:
We will need to use the Pythagorean Theorem.
A^2 + B^2 = C^2
45^2 + B^2 = 500^2
Subtract 45^2
B^2 = 500^2 - 45^2
Simplify
B^2 = 247,975
Take square root so B is alone
B = 497.9708
Round
B = 498

The answer is <u>5.25</u>
First, you need to list all of the numbers from least to greatest. Then, you remove the sides (first 3.9 and 6.2 being the least and the greatest numbers). You then have 4.9 and 5.6 so you need to add them together (getting 10.6) and divide your answer by 2 (getting 5.25).
Hope I helped and good luck :)
