The answer is 20 quarters <span />
<span>If you have a right triangle and the side AC is the hypotenuse (the longest side) then your equation would be a^2+b^2=c^2 like mentioned before. but you have to put the numbers in the correct spot.
a in the equation= side ab, b in the equation= side bc, and c in the equation= side as
so..
3^2+b^2=7^2
9+b^2=49
b^2=40
b= the square root of 40 or
2 square roots of 10 (2 then square root sign with 10 in the square root) which would probably be the simplest form.</span><span>

What are you supposed to do for this is there answers?
Answer:
7
Step-by-step explanation:
Set up the equation ... 60 + 40X = total charges... where X is the number of hours (8.5)
60 + 40(8.5) = ?
60 + 340 = ?
400 = total charges
