I have a learning disability it doesn't effect me until I try to do anything math related I just never get the concept so it would mean a lot if you could answer these questions and make it as easy as possible to understand how you did them thanks. how many groups of seven dogs can be selected from a group of 14?

out of 30 animals how many can you select from a group of 3?

there are 12 singers in a choir how many groups of four can you choose to sing?

in a club of 25 how many groups of five can you choose to run a bake sale?

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:

Aefg - almn. find the ratio of aefg to almn. a)1: 4 b)1: 2 c)2.1 d)4: 1

Select all the expressions that will include a remainder.
