docker41 [41]

Answer:

A = $11117.25

Step-by-step explanation:

Given the following data;

Principal = $7,500

Interest rate = 3.975% = 3.975/100 = 0.03975

Number of times, n = 2

Time, t = 10 years

To find the future value, we would use the compound interest formula;

A = P(1 + \frac{r}{n})^{nt}

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 = 7500(1 + \frac{0.03975}{2})^{2*10}

A = 7500(1 + 0.019875)^{20}

A = 7500(1.019875)^{20}

A = 7500(1.4823)

A = $11117.25

The total length of three boards is 7/8 of a yard. The length of two of the boards are 1/4 of a yard and 3/16 of a yard. What is
grigory [225]

Answer:

7/16 of a yard

Step-by-step explanation:

Let's put the boards to the same denominator so it's easier.

Let's go with a denominator of 16

1/4= 4/16

7/8= 14/16

3/16 stays the same.

So, 4/16+3/16+x=14/16

7/16+x=14/16

x=7/16 of a yard, the length of the 3rd board.
