***please work out and amswer*** thank you!!! Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! we know "W varies inversely with square of T", so we can write the proportion as
W = k / (T^2) where k is the constant of proportionality
for W=63 when T is 3 we have
63 = k / 3^2 and k = 63 * 9 = 567
now when T = 12, we have
W = 567 / 12 = 47.3
