A hot air balloon descends at the rate of 5 ft per minute for 6 minutes and then rises at the rate of 3 ft per minute for 8 minutes. Write this information using integers and give the net result on balloon height.
since distance = speed * time, you get
-5*6 + 3*8 = _____
I get -30+24=-6
To represent the descent of the hot air balloon, we can use the integer -5 ft/minute for 6 minutes.
Therefore, the initial descent of the hot air balloon can be represented as (-5 ft/minute) x (6 minutes) = -30 ft.
Next, to represent the ascent of the hot air balloon, we can use the integer +3 ft/minute for 8 minutes.
Therefore, the ascent of the hot air balloon can be represented as (+3 ft/minute) x (8 minutes) = +24 ft.
To find the net result on balloon height, we add the descent and ascent together:
-30 ft + 24 ft = -6 ft.
The net result on the balloon height is -6 ft.
To represent the descent of the hot air balloon, we can use the integer -5, since it is descending at a rate of 5 ft per minute. Multiplying this by the time in minutes (6), we get -5 * 6 = -30 ft, indicating a descent of 30 ft.
Similarly, to represent the ascent of the hot air balloon, we can use the integer +3, since it is rising at a rate of 3 ft per minute. Multiplying this by the time in minutes (8), we get 3 * 8 = +24 ft, indicating an ascent of 24 ft.
Now, to find the net result on the balloon's height, we can sum the descent and ascent. Using the rule of adding integers, we have -30 + 24 = -6.
Therefore, the net result on the balloon's height is a descent of 6 ft.
