Question 39600: This is a problem from a textbook that I just do not understand how to solve. I have been reading it over and over and still don't get it. Can you please help?
Sailboat speed. 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 square feet and a displacement of 23,245 pounds.
b) Solve the formula for d.

a) Find S to the nearest tenth:
Substitute the given values of: A=810, d = 23,245.

To the nearest tenth.
b) Solve the formula for d.
Multiply both sides by
Divide both sides by S.
Raise both sides to the 3/2 power.
