Answer:
use the formula- 10^2+x=15^2 and then subtract 15^2 from 10^2
Step-by-step explanation:
the rate of change is +2
Every time the number is given, the number goes up by 2
Changed both of them to a fraction
Answer:
1,715 feets
Step-by-step explanation:
Give the following :
General descent rate of hot air balloon = 200 - 400ft/min
Six balloons descend at a rate of 245 ft/min for four minutes
The total change in altitude for all six balloons :
From speed = distance / time
Speed = 245 ft / min ; time = 7 minutes
Hence distance descended by the six balloons :
245 ft/min × 7 minutes = 1,715 fts
Hence total change in altitude = 1,715 feets
