the number of gallons of bottled water N consumed by a person in one year is approximated by N=0.733t + 8.398, where t is the number of years since 1971. Predict the number of gallons consumed by a person in 1985.

Step-by-step explanation:

N = 0.733t + 8.398

N = 0.733(1971) + 8.398

N = 1,453.141

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.
