Two hot air balloons are flying above a park. One balloon started at a height of 3,000 feet above the ground and is decreasing in height at a rate
of 40 feet per minute. The second balloon is rising at a rate of 50 feet per minute after beginning from a height of 1,200 feet above the ground.

Given that h is the height of the balloons after m minutes, determine which system of equations represents this situation.
A. h=3,000-40m
h=1,200+50m

B. h=3,000+40m
h=1,200-50m

C. h=3,000m-40
h=1,200m+50

D. m=3,000-40h
m=1,200+50h

A

Step-by-step explanation:

the first balloon starts at 3,000 and goes down 40 so this would make it a negative 40 so 3,000-40 but it does this every minute so 3,000-40m

the second balloon is going up starting at 1,200 and going up by 50 so positive 50 this would be 1,200+50 and it does this every minute so 1,200+50m

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
