Answer:
18.8496 units (rounded o1ff to four decimal places)
Step-by-step explanation:
Arc length = 2 × π × r × 
r (radius) = 12 units ÷ 2 = 6 units
Central angle = 180°
For our semicircle, the arc length = 2 × π × 6 ×
= 18.8495559215 units
Or 18.8496 units (rounded o1ff to four decimal places)
The current population is equal to 134% compared to the previous population. So form a proportion 134/100=46900/x. Which equals to 35000
The first thing we need to know is that the Jennifer-Chelsea ratio is as follows:
3: 2
Equivalently:
3/2
To know how much Jennifer invests, we have to:
(3 / (2 + 3)) = x / 125000
Clearing x:
x = 125000 * (3 / (2 + 3)) = 75000
answer
Jennifer invest 75000 $
