Answer:
The final height of the balloon is 1621.242 feet
Explanation:
In this question, we are to calculate the final height of a ballon that rises and falls
Initial height rise it has from the ground was
2,150.825 feet
0.825 feet to fraction is ; 825/1000 = 33/40
Thus it is 2,150 33/40
We no subtract the height to which it falls by which is 583 1/3 feet
This would be;
2,150 33/40 - 583 1/3
= 88,183/40 - 1750/3
= (264,549-70,000)/120 = 194549/120 = 1,621.241666666667 which is approximately 1621.242 feet
