A scuba diver dove from the surface of the ocean to an elevation of -69 9/10 feet at a rate of -21.5 feet per minute. After spending 13 minuets at that elevation the diver ascended to an elevation of -8 9/10 feet. The total time for the diver so far was 20 1/8 minutes. What was the rate of change in the divers elevation during the ascent? Round your answer to the nearest hundredth.

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.

step-by-step explanation:

the anwser is x< -17/2
