Given that;

It cost her $10 for every $100;

$\text{For \$500 it will cost her 5}\times\text{ \$10 = \$50}$

It also cost her a one-time fee of $150.

The total cost for her $500 loan is;

$\begin{gathered} C=\text{ \$50 + \$150} \\ C=\text{ \$200} \end{gathered}$

Therefore, the total cost for her $500 loan is;

$\text{\$200}$

Circle towns limit form a perfectly circular shape that has a population of 20000 in the population density of 480 people per sq

Alex

Answer:

$D =\frac{P}{\pi X^2}$

And solving for the radius we got:

$X = \sqrt{\frac{P}{\pi D}}$

And replacing the data given we got:

$X = \sqrt{\frac{480 \frac{people}{km^2}}{\pi *20000 people}}= 0.0874Km$

And this value converted to meters is $X = 87.40 m$

Step-by-step explanation:

For this case we know the population size $P = 20000$ and we also know the population density $D = 480 \frac{people}{km^2}$

We can assume that the area is a circle. We also know that the formula for the population density is given by:

$D= \frac{P}{A}$

Where P represent the number of people and A the area. Since we are assuming a circle then the area is given by:

$A = \pi X^2$

With X the radius of the circle

And then the populationd density become:

$D =\frac{P}{\pi X^2}$

And solving for the radius we got:

$X = \sqrt{\frac{P}{\pi D}}$

And replacing the data given we got:

$X = \sqrt{\frac{480 \frac{people}{km^2}}{\pi *20000 people}}= 0.0874Km$

And this value converted to meters is $X = 87.40 m$

How many two-digit positive integer less than 25 have the property that they are divisible by each of their digits? List themZ

Ierofanga [76]

This is easy, since there aren't many positive two digit integers under 25.
Just go through and check each one!

10 - not divisible by 0.
11 - divisible
12 - divisible
13 - not divisible by 3.
14 - not divisible by 4.
15 - divisible
16 - not divisible by 6.
17 - not divisible by 7.
18 - not divisible by 8.
19 - not divisible by 9.
20 - not divisible by 0.
21 - not divisible by 2.
22 - divisible
23 - not divisible by 2 or 3.
24 - divisible

To sum it up, the numbers 11, 12, 15, 22, and 24 are divisible by each of their digits.

Hope this helps (and your fortune is "Good things will come your way if you keep eating pizza.")!
