How can you tell by looking at the prime factorization of 17,640 that
is not a whole number? ​

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

3 is greater then both of those numbers

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.
