Translate the following: A number decreased by 14 is less than 25. *

ioda

Answer:

x - 14 < 25

Step-by-step explanation:

You solve this by replacing the words with the number, letter or symbol they equal. So a number is x and decreased is subtraction. So far you have, x - 14. Then you look at less than and you know that the less than symbol is < so you plug that in and then you put 25 on the end.

Solve for the amount of monthly interest that is owed on an interest-only loan based on the following facts: Loan amount $115,00

aev [14]

The annual interest owed is

... 7% × $115,000 ≈ $8050

The monthly interest owed is 1/12 that amount.

... (1/12) × $8050 ≈ $671

_____

Some calculators are able to use 7% as a factor; others require you use the decimal equivalent, 0.07.

I don't understand how to do this

ddd [48]

Answer:

64 $\pi$ in²

Step-by-step explanation:

I did not ever do a problem like this, however this is the beauty of math, you can easily reverse engineer it.

Remember,

A = $\pi$ $r^{2}$

And if we have 4 circles that means the area of one circle is 1/4th the total

So,

A= $\frac{\pi r^{2} }{4}$

Assuming that 16 is the radius squared times 4 lets ignore that squared for now because when going backwards we would get rid of the squared last as that was the first step.

A= $\frac{16\pi }{4}$ = $\frac{4\pi }{1}$ =4 $\pi$

Now lets get it back to $r^{2}$ by square rooting the 4

A= $\sqrt{4\pi }$ =2 $\pi$

The radius of one small circle is 2. Therefore; the diameter would be 4 for each. This in mind we know that two small circles diameters make up the radius of the larger circle we will multiply it by two again.

This gives us a final radius of the bigger circle of 8

Therefore, the area of the bigger circle is 8² $\pi$ which simplifies to 64 $\pi$

And a final answer of

64 $\pi$ in²

Hope this helps :)
