Can you please check my work. I asked this question yesterday but no one helped me. Thank you , I really appreciate it
A hot air balloon was at a height of 60 feet above the ground when it began to ascend. The balloon climbed at a rate of 15 feet per minute.
a) make a table that shows the height of the air balloon after climbing for 1,2,3,&4 minutes.
minutes:1 2 3 4
-------------------
height:15 30 45 60
(ft)climbed
b)let T represent the time in minutes since the balloon began climbing. wRITE AN ALGEBRAIC EQUATION FOR THE sequence that can be used to find height,h,of the balloon after T minutes.
h=15T
c) use your equation from part b to find the height, in feet, of the hot air balloon after climbing for 8 minutes.
h=15T
h=15(8)
h=120 ft
Are these correct. Thanks for taking the time to check my work
Since it asked for the height of the balloon , should you not have added the original 60 feet to each of your answers ?
e.g. after 2 seconds
= 60 feet + 30 new feet = 90 ft
so I would give my equation as
height = 60 + 15t
Your answers describe the height of the balloon after it started to rise.

*25

360
+1440
_______
1,800
a) The table you've made looks correct. At each minute, the height of the balloon increases by 15 feet, so after 1 minute it would be 60 + 15 = 75 feet, after 2 minutes it would be 60 + 15 + 15 = 90 feet, and so on. Your table matches this pattern.
b) The algebraic equation you've written is correct. The height, h, of the balloon after T minutes can be found by multiplying the rate of ascent (15 feet per minute) by the time T: h = 15T. This equation represents the linear relationship between the time and the height of the balloon.
c) To find the height of the balloon after 8 minutes, you can substitute T = 8 into the equation h = 15T:
h = 15(8)
h = 120 feet
Your answer of 120 feet is correct. After climbing for 8 minutes, the hot air balloon would be 120 feet above the ground.
Overall, your work is correct. Well done!
