To find the annual rate of interest, here's what we need to do:

In this case:
333/4500 x 100%
=37/500 x 100%
=7.4%
Therefore the answer is 7.4%.
Hope it helps!
Answer: g=2
Step-by-step explanation:5.5g+3=2.5g+9
We move all terms to the left:
5.5g+3-(2.5g+9)=0
We get rid of parentheses
5.5g-2.5g-9+3=0
We add all the numbers together, and all the variables
3g-6=0
We move all terms containing g to the left, all other terms to the right
3g=6
g=6/3
g=2
Assuming the square and the semicircle aren't merged somehow, and we need to calculate their full area, we should take into account:
Area of a square:
(Side length)² = 22² = 484 square inches
Area of a circle with a diameter of 22inch:
3'14 · (radius)² = 3'14 · 11² = 379'94 square inches
Since we have half a circle, the total areas to add will be:
1/2 · 379'94 + 484 = 673'97
