What is the answer to 17x+10=180

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

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.

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
