H+3h+4h=100 how do i get h?

Dominik [7]

Answer:

h = 12.5

Step-by-step explanation:

Simplifying

h + 3h + 4h = 100

Combine like terms: h + 3h = 4h

4h + 4h = 100

Combine like terms: 4h + 4h = 8h

8h = 100

Solving

8h = 100

Solving for variable 'h'.

Move all terms containing h to the left, all other terms to the right.

Divide each side by '8'.

h = 12.5

Simplifying

h = 12.5

Dr drake is thinking about retirement and decides to sail around the world once he retires. He buys a sailboat for 125000. He bo

Akimi4 [234]

Answer:

$46875.

Step-by-step explanation:

We have been given that Dr. Drake buys a sailboat for 125000. He borrows the money at an APR of 7.5% for five years.

We will find total interest after 5 years by using simple interest formula.

$A=P(1+rT)$ , where,

A= Amount after T years.

P= Principal amount.

r= The annual interest rate (in decimal form).

T= Time in years.

First of all we will convert our given interest rate from percent to decimal form.

$7.5\text{ Percent}=\frac{7.5}{100} =0.075$

Now let us substitute our given values in above formula.

$A=125,000(1+(0.075*5))$

$A=125,000(1+0.375)$

$A=125,000(1.375)$

$A=171875$

To find the amount of total interest we will subtract principal amount from 171875.

$\text{Total amount of interest}=171875-125000$

$\text{Total amount of interest}=46875$

Therefore, the total interest after 5 years will be $46875.
