Answer:
He will save 590 dollars by the end of the year
Answer: 1. ∠A= 80.75° 2. 41.79 
Step-by-step explanation:
Since, According to the sines low,

Here, CB= 4.1 cm, AB = 3.3 and ∠ C = 52.6°

⇒ 
⇒ 
⇒ A = 80.75°
2. Since, the area of the given figure = Area of the rectangle having dimension 8.3 × 4.2 + Area of the half square of radius 2.1
=34.86 + 6.93
= 41.79 square cm
*your
If the ratio is 5:3, then you divide 275 by 5, and then multiply it by 3. If you test the result, you'll find that the ratio fits.
Why did you delete my answer it was correct
We are asked to solve for the interest during the year given that it is compounded monthly, we are given with the formula A = P(1+r)^n. The solution is shown below:
A = P (1+r)^n
A = $5,000 (1+ 3.5/12)^(12*1)
A = $5,000 (1.000292)^12
A = $5,177.84
