Answer:
if you're still wondering, it is 137.2.
Explanation:
(7/5)^3. 7^3 is 343, and 5^3is 125. so, it is 343/125.
then, we can set up the rest of the equation, which would be v/50=343/125.
cross multiply, and you get 125v=17150.
divide both sides by 125, and you're left with v= 137.2
no need to round to the nearest tenth or hundredth.
hope this helped!
