Subtract 13.09 from 21.59 giving you 8.5. Since the amount of space on both the left and right margin have to be equal you would divide by 2 to get 4.25 on the left margin as well as the right.
Answer:
The population density is 618.93 per square mile.
Step-by-step explanation:
It is given that,
No. of people, N = 70,000
The radius of a city's town hall, r = 6 miles
We need to find the population density. It can be calculated by the formula i.e. number of people divided by area of land such that,
![P=\dfrac{N}{A}\\\\P=\dfrac{N}{\pi r^2}\\\\P=\dfrac{70000}{\pi (6)^2}\\\\P=618.93\ \text{per square mile}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7BN%7D%7BA%7D%5C%5C%5C%5CP%3D%5Cdfrac%7BN%7D%7B%5Cpi%20r%5E2%7D%5C%5C%5C%5CP%3D%5Cdfrac%7B70000%7D%7B%5Cpi%20%286%29%5E2%7D%5C%5C%5C%5CP%3D618.93%5C%20%5Ctext%7Bper%20square%20mile%7D)
So, the population density is 618.93 per square mile.
Answer:
$17,685.45
Step-by-step explanation:
We will use the compound interest formula to solve this:
![A=P(1+\frac{r}{n} )^{nt}](https://tex.z-dn.net/?f=A%3DP%281%2B%5Cfrac%7Br%7D%7Bn%7D%20%29%5E%7Bnt%7D)
<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
The first step is to change 12% into a decimal:
12% ->
-> 0.12
Next, lets plug in the values:
![A=8,000(1+\frac{0.12}{1})^{1(7)}](https://tex.z-dn.net/?f=A%3D8%2C000%281%2B%5Cfrac%7B0.12%7D%7B1%7D%29%5E%7B1%287%29%7D)
![A=17,685.45](https://tex.z-dn.net/?f=A%3D17%2C685.45)
After 7 years, you will have $17,685.45
