Use cross products to solve the proportion. StartFraction 4 over 3 EndFraction = StartFraction x over 12 EndFraction
1. Use cross products:   (4)(12) = 3x
2. Multiply:          48 = 3x
3. Divide both sides by 3: = x

i will apply the correct answer!

Apinhole camera is made out of a light-tight box with a piece of film attached to one side and pinhole on the opposite side. the optimum diameter d(in millimeters) of the pinhole can be modeled by d=1.9[ (5.5 x 10^-4) l) ] ^1/2, where l is the length of the camera box (in millimeters). what is the optimum diameter for a pinhole camera if the camera box has a length of 10 centimeters
