Answer:
12
Step-by-step explanation:
We have been given that in an account an amount of 7,650 is invested at 9.15 percent compounded quarterly for 8 years and 6 months.
We will use compound interest formula to find our answer.
,
Where, P= principle amount, A= amount after T years, n= period of compounding and r = interest rate (decimal).
Let us substitute our given values in our formula.
Therefore, after 8 years and 6 months our amount will be 16505.497.
Answer:
D. b = r+z
Step-by-step explanation:
Given the expression b-r = z, we are to solve for b. To do this, we will add 'r' to both sides of the equation as shown;
b-r+r = z+r
Since -r+r = 0, substitute:
b+0 = z+r
b = z+r
Hence the resulting equation when r is added to both sides of the equation is b = z+r
Hence option D is correct
Answer:
Step-by-step explanation:
<u>The interior and exterior angles are supplementary:</u>
- A + 108° = 180°
- A = 180° - 108°
- A = 72°
