Ira Lisetskai [31]
The correct question is
A family is building a circular fountain in the backyard. The yard is rectangular and measures 10x by 15x and the fountain is going to be circular with a radius of 4x. Once the fountain is built, what will be the area of the remaining yard?

Step  1
find the area of rectangular yard (A1)
A1=(10*x)*15*x=150*x² units²

Step 2
find the area of the circular <span>fountain (A2)
A2=pi*r</span>²---------> pi*(4x)²=16*pi*x²

Step 3
find <span> the area of the remaining yard (A3)

A3=A1-A2----------> 150*x</span>²-16*pi*x²----> x²*[150-16*pi]----> 2*x²*[75-8*pi]

the answer is the option A) 
<span> 2x</span>²<span> (75-8pi )</span>

Describe how the graph of y= x^2 can be transformed to the graph of the given equation.
7nadin3 [17]

Answer:

b

Step-by-step explanation:

Given y = x² then y = x² + c is a vertical translation of y = x²

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here c = - 12 < 0

Thus y = x² - 12 is the graph of y = x² shifted 12 units down → b

What is the volume of a cube with<br> inch sides?<br> 2<br> 1
son4ous [18]

Answer/Step-by-step explanation:

The given park of sugar cubes has has 24 cubes of sugar.

The cube of sugar has equal side length of ½ in.

Volume of the park of sugar cubes = 24 * volume of 1 cube of sugar

Volume of 1 cube of sugar = \frac{1}{2} * \frac{1}{2} * \frac{1}{2}

= \frac{1}{8} in^3

Volume of the park of sugar cubes = 24 * \frac{1}{8} = \frac{24}{8} = 3 in^3

Your parents have a credit card with a balance of $3,287.90 at an interest rate of 14.5% APR. They pay $1,200.00 each month on t
aleksandrvk [35]

It will take them approximately 3 months to pay off the balance on the credit card

<h3 /><h3>First Month</h3>

To solve this problem, we need to find the interest on 3287.90 at 14.5%

for the first month, we would have

\frac{x}{3287.90}=\frac{14.5}{100}  \\x=476.74

Now we divide this by 12 to give the interest payable on the first month

\frac{476.75}{12}=39.73

So we have

(3287.90+39.73)-1200=2127.63

<h3>Second Month</h3>

We would do the same thing for the second month and it will give us

(\frac{x}{2127.63}=\frac{14.5}{100})/12\\\frac{308.506}{12}=25.71

For the second month, we have $25.71 as the interest payable

We can calculate how much would be left after the second month.

(2127.63+25.71)-1200=953.34

<h3 /><h3>Third Month</h3>

In the third month, since the balance remaining is less than the monthly payment schedule, we can assume they'd pay everything off which is 953.34.

From the calculations above, we can see that it'll take them 3 months to pay off the credit card balance.

The balance at the end of each month are;

  • $2,127.63
  • $953.34
  • $0
