Question 124878: I have not idea what they are asking????
The sail area-displacement ratio S provides a measure of the sail power available to drive a boat. For a boat with a displacement of d pounds and a sail area of A square feet S=16Ad^-2/3.
a. Find S to the nearest tenth for the Tartan 4100, which has a sail area of 810 feet and a displacement of 23,245 pounds.
b. Solve the formula for d.

S=16AD^-2/3
S=16*810*23,245^-2/3 [NOTE: X^-2/3=1/CUBE ROOT(X^2)].
S=12,960
S=12,960/(CUBE ROOT 540,330,025)
S=12,960/814.5
S=15.9 IS THE ANSWER.
