Answer:
1 in^2 = 5 mi * 5 mi = 25 mi^2
2.5 in^2 (25 mi^2/in^2) = 62.5 mi^2
Step-by-step explanation:
The number of years is 4.781 in which $21,136.18 amount to $75,514.55 at 27.54% per annum when compounded quarterly and this can be determined by using the formula of the compound interest.
Given :
- Principal amount = $21136.18
- Final amount = $75514.55
- Interest rate per annum = 27.54%
- Compounded quaterly.
The formula of the compound interest is given by:

where A is the final amount, P is the principal amount, r is the interest rate, t is the time in years, and 'n' is a number of times interest applied.
Now, substitute the values of known terms in the above formula.


Now, take the log on both sides.

19.1237 = 4t
t = 4.781 years
Therefore, the correct option is B).

Answer:
308
Step-by-step explanation:
We are given;
- Money deposited (Principal) as 3850
- Annual rate of interest as 8%
- Period or time = 1 year
We are required to determine the interest accrued;
- We are going to use the formula of calculating simple interest;
- Simple interest = (P × R × T)/100
Where P is the principal, R is the rate while T is the time.
Therefore;
Simple interest = (3850 × 8 × 1) ÷ 100
= 308
Therefore, the money earned simple interest of 308 within 1 year
Answer:
Step-by-step explanation:
-4 (-2x - 8) = -48
-4×(-2x)+4×8=-48
8x+32=-48
8x=-48-32
8x=-80
x=-10
The answer is -10
