Given:
Principal = $14850
Rate of interest = 4% compounded semiannually.
Time = 3 years
To find:
The amount after 3 years.
Solution:
Formula for amount is:

Where, P is principal, r is the rate of interest in decimal, n is the number of times interest compounded and t is the number of years.
The interest is compounded semiannually, so n=2.
Putting
in the above formula, we get



On further simplification, we get



Therefore, the amount in the account after three years is $16723.51.
Answer:
s = 11
Step-by-step explanation:
Given
=
( cross- multiply )
8(s - 2) = 72 ( divide both sides by 8 )
s - 2 = 9 ( add 2 to both sides )
s = 11
We can write a system of equations.
x + y = 77
y = x + 5
Plug in x + 5 into the first equation:
x + y = 77
x + (x + 5) = 77
So this is our answer.
Answer:
22 in
Step-by-step explanation:
<u>circumference of a circle = 2 π r</u>
where radius (r) = 7/2 in. = 3.5 in
C = 2 π (3.5)
= 22 in
