Answer:
okay nice to know sir.
Step-by-step explanation:
Falling at the rate of 2.5 m/s for 45 seconds, the anchor fell
(2.5 m/s) x (45 s) = 112.5 meters .
If it wound up only 40 meters underwater, then it must have fallen
(112.5 m - 40 m) = 72.5 meters
from its storage position on the big cruise ship,
before it ever reached the water.
Since it was falling at the rate of 2.5 m/s, it took
(72.5 m) / (2.5 m/s) = 29 seconds
to get down to the water surface after it started dropping.
So,
We simply invert and multiply.

Re-arrange the numbers so that they are easier to understand.

Factor.

Cancel out 1's.
Answer:
Step-by-step explanation:
Circumference of circle = 7π cm
θ = 2π × 5.5/(7π) = 11/7 radians
After 5 months you will have $160
so,
10
10×2 =20
20×2=40
40×2 =80
80×2=160
hence proved that after 5 months you will have $160
