Question 1016054: The wind speed s in miles per hour can be modeled by the formula s=150 sqrt (p/a) , where a is the area of a sale in square feet and p is the pressure of the wind on the sale in pounds per square feet. Determine the area of a sail if the wind speed is 75 mph and the pressure is 20 pounds per square feet.
So far I have 75= 150 sqrt (20/a)

You can put this solution on YOUR website!
+75+=+150%2Asqrt%28+20%2Fa+%29+
+1%2F2+=+sqrt%28+20%2Fa+%29+
Square both sides
+1%2F4+=+20%2Fa+
Multiply both sides by +4a
+a+=+80+
area of sail is 80 ft2
