A store charges a restocking fee for any returned item based upon the item price. An item priced at $200 has a fee of $12. An it

lyudmila [28]

Answer:

Both ratios reduce to the same ratio 3/50, so the restocking fee is proportional.

Step-by-step explanation:

For the $200, the restocking fee is $12, so the ratio of the restocking fee to the price of the item is 12/200.

For the $150, the restocking fee is $9, so the ratio of the restocking fee to the price of the item is 9/150.

Now we find out if the ratios 12/200 and 9/150 are equal.

12/200 = 3/50

9/150 = 3/50

Both ratios reduce to the same ratio 3/50, so the restocking fee is proportional.

Find the perimeter of the window to the nearest hundredth.<br><br> also how do you do it?

k0ka [10]

<em>I am assuming the picture is of a stained glass window in the shape of a semicircle</em>.

Answer: 7.71 feet.

Step-by-step explanation: <em>The formula for finding the circumference of a circle is $\frac{1}{2}$ π × d + d.</em>

The diameter is 3 feet. Substitute this into the equation:

$\frac{1}{2}$ π × 3 + 3.

Solve -

3.14 × 3 = 9.42

$\frac{1}{2}$ of 9.42 = 4.71

4.71+3 = 7.71

Round -

The answer is already rounded.

Hope this helped!~

What is the equation of the line that passes through the point (2,-4) and has a slope of -2

kvv77 [185]

Answer:

The answer is

$\huge y = - 2x$

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

From the question we have

$y + 4 = - 2(x - 2) \\ y + 4 = - 2x + 4 \\ y = - 2x + 4 - 4$

We have the final answer as

Hope this helps you
