Sammy likes to do pushups as part of his exercise routine. When he has finished 9 pushups, he is 45% through one set. How many pushups does Sammy do in one whole set?

20

Step-by-step explanation:

The question says

9 pushup is equal to 45percent of a set.

So we are required to find number of pushups for a whole set

To solve this we will have to do cross multiplication

9 pushup = 0.45

Unknown = 1

When we cross multiply we will have 9x1/0.45 to get the unknown

= 9/0.45

= 20 pushups in a whole set

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
