He needs to go 3280 more yards because there are 1760 yards in one mile and he has to do three miles so you multiple that by three to get 5280 yards in three miles. Sam has gone 2000 yards after 8 laps so you subtract the two to get 3280 more yards.
She went 3.5 feet per second down for 90 seconds
3.5*90 = 315 feet below
2.2*30 = 66 feet up
315-66 = 249 feet below.
So, she must go up at 4.8 feet per second.
249/4.8 = 51.875 seconds
52 seconds when rounded
Answer:
If it went up it would be: 50596.35 and if it went down it would be: 7556.66
Step-by-step explanation:
Here will be the function if it went up:
20000(1+0.0475)^20
Here’s if it went down:
20000(1-0.0475)^20
Answer:
130
Step-by-step explanation:
ABC = 180 - 120 = 60
ACB = 180 - 70 - 60 = 50
ACD = 180 - 50 = 130
