Answer:
D
Step-by-step explanation:
This is because when making a triangle, the two shortest sides have to add up to be bigger than the biggest side. For example, A would work because if you did 4+6, it would equal 10 which is bigger than the biggest side. B and C add up to something bigger than 6. However, D is different. If you do 2+4, that equals 6. It has to be bigger than six, not equal
C would be your answer i hope i helped you :) sorry if i’m incorrect. i’m not sure
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
