Ok s we know the total cost is $320 so if the cost for the supplies is $70 the n we will subtract 70 from 320 leaving us with $250. The jobs is 5 hours so we will divide 250 by 5 and get 50 so the total cost per hour is $50
hope this helps!
The answer is
![r= \sqrt[3]{GMT^{2}/4 \pi^{2}}](https://tex.z-dn.net/?f=r%3D%20%5Csqrt%5B3%5D%7BGMT%5E%7B2%7D%2F4%20%5Cpi%5E%7B2%7D%7D%20)

Move

to the other side of the equation:

Rearrange:

Since
![x^{3}= \sqrt[3]{x}](https://tex.z-dn.net/?f=%20x%5E%7B3%7D%3D%20%5Csqrt%5B3%5D%7Bx%7D%20%20)
, then
Answer:
(4^3)3 and 4^3 • 4^3 = 192 and 4096 = No
(3^4)^4 and 3^8 • 3^8 = 43046721 and 43046721 = Yes
6^4 • 3^4 and 18^8 = 104976 and 11019960576 = No
4^3 • 5^3 and 2^0 = 8000 and 1 = No
