To find the ratio between two numbers, divide the first number by the second number. To find the ratio of 28 gallons to 56 gallons divide 28 gallons by 56 gallons.

$\dfrac{28~gallons}{56~gallons} = \dfrac{1 \times 28}{2 \times 28} = \dfrac{1}{2}$

The ratio is 1:2

The employee will need to figure out how many groups of 0.4 points they have beyond a score of 2.6. To do this subtract 3.4 and 2.6.

3.4 - 2.6 = 0.8
This is two groups of 0.4.

So, 0.5% + 1% + 1%= 2.5 % pay increase.

The steps needed to solve the given equation is required.

Adding the opposite value of the constant to both sides.

Divide both sides by the coefficient of the variable.

The solution to the equation is

The given equation is

In order to solve this we first move constants to the side opposite of the variable.

This is done by adding the opposite value of the constant to both sides.

Here is the constant so we add to both sides.

Now, we divide both sides by the coefficient of the variable.

The amount in account after 7 years is $ 5499.445

Solution:

The formula for total amount in compound interest is given as:

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

A = the future value of the investment/loan, including interest

P = the principal investment amount (the initial deposit or loan amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per unit t

t = the time the money is invested or borrowed for

Here given that,

A = ?

P = 4000

t = 7 years

$r = 4.6 \% = \frac{4.6}{100} = 0.046$

n = 2 ( since compounded semi annually)

Substituting the values in formula, we get

$A = 4000(1+\frac{0.046}{2})^{2 \times 7}\\\\Simplify\ the\ above\ expression\\\\A = 4000(1+0.023)^{14}\\\\A = 4000(1.023)^{14}\\\\A = 4000 \times 1.37486\\\\A = 5499.445$

Thus amount in account after 7 years is $ 5499.445
