In a right triangle, the length of the hypotenuse is 20 inches and the length of one leg is 15 inches. what is the length of the other leg in inches? a. 5√ 7 b. 25 c. √ 7 d. 5

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
