What scale factor is needed for a similarity transformation to transform a square into a square with twice the area?

What scale factor is needed for a similarity transformation to transform a cube into a cube with twice the volume?

Alberto figures that the probability of his hockey team winning on saturday is 65%. Alvin figures that the probability of his basketball team winning on saturday is 70%. Assume that the events are independent and that the boys estimates of the probability...

Okay so all you have to do is plug the values into the formula of d=m/v. The 'd' represents the density which has units of grams per cm cubed (in this case), 'm' stands for the mass in grams, and 'v' stands for the volume in cubic centimeters. All you nee...

Great, thanks so much! :) And yes Ka doesn't have any units since K is an equilibrium constant.
