A savings account earns 7.2 (APR) compounded monthly, so it earns 0.6% each month. Cooper has $1500 in the account now. if he de

iragen [17]

Answer-

Cooper will receive $12.00 at the end of the month.

Solution-

Cooper has $1500 in the account now and he deposits an additional $500 at the beginning of the month.

So the total principal becomes 1500+500 = $2000

Given here,

APR = annual percentage rate = 7.2%

But as we have to calculate the monthly interest, so monthly interest rate would be $=\dfrac{7.2}{12}=0.6\%$

Time period = 1 month

So, the interest after 1 month will be,

$\text{interest}=\dfrac{\text{Principal}\times \text{Rate of interest}\times \text{Time period}}{100}$

$=\dfrac{2000\times 0.6\times 1}{100}$

$=\$12.00$

Therefore, Cooper will receive $12.00 at the end of the month.

2/5 divided by 1/3 equals

aniked [119]

Answer:

6/5, or 1 1/5

Step-by-step explanation:

I use a method called KCF, which means Keep Change Flip. Here is your current expression: 2/5 / 1/3. First, keep the first fraction. Next, change the sign into a multiplication symbol. Now, you have 2/5 x 1/3. Finally, flip the last fraction into 3/1. Now, this is your expression: 2/5 x 3/1. Multiply numerator by numerator, denominator by denominator. Your final answer is 6/5, or 1 1/5 simplified.

The population density is approximately 4 people per square mile

<h3>Calculating Population Density </h3>

From the question, we are to determine the population density

Population density is given by the formula,

$Population\ density = \frac{Number\ of\ people}{Land\ area}$

Number of people in the town = 12620 people

Now, we will determine the land area of the town

From the given shape,

Land area of the town = (60 × 65) - (25 ×40)

Land area of the town = 3900 - 1000

Land area of the town = 2900 square mile

∴ Population density = $\frac{12620}{2900}$

Population density = 4.3517

Population density ≅ 4 people per square mile

Hence, the population density is approximately 4 people per square mile
