yes

step-by-step explanation:

yes

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, it becomes,

hence, first option 'a'   is correct.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
