Complete the explanation of how an estimate helps you to place the decimal point when multiplying
2.7 x 7.3.

By estimating with whole numbers, 3 x( )=( ) helps me know that the decimal point should
be placed so that the answer is close to ( ).

How can you decide witch operations to use to slice a two step equation

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:

Algebraically prove that a clockwise and counterclockwise rotation of 180° about the origin for triangle abc are equivalent rotations.
