Answer:
Interest earned = $32.835
Step-by-step explanation:
Given the following data;
Principal = $275
Number of times = 0.5
Interest rate = 2.9% = 0.029
Time = 4 years
To find the interest earned, we would use the compound interest formula;
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
n is the number of times the interest is compounded in a year.
t is the number of years for the compound interest.
Substituting into the equation, we have;

A = $307.835
Interest earned = 307.835 - 275
Interest earned = $32.835

Answer:
c= 1.74
Step-by-step explanation:
4520 = 3000(c)-700
4520=3000c-700
+700 +700
5220=3000c
c=1.74
to check to see if this is right you would do this:
4520=3000(1.74)-700
4520=5220-700
4520=4520
The angle of depression equals 32.
A way that you can solve this is by finding angle c. Angle C would be the same as the angle of depression because of alternate angles being congruent.
So you do the triangle angle sum theorem.
58+90+x=180
Simplify
148 +x=180
Subtract 148 from both sides
x=32
So Since angle c equals to 32 degrees, then the angle of depression is also 32 degrees.
I think it’s 12
1/3 = 4/12
1/4 = 3/12
Hope it’s correct
