padilas [110]

Answer:

The tax Jenna and Richie pay on the gifts is <u>$3.85</u>.

Step-by-step explanation:

Given:

Cost of scarf = $12.45.

Cost of necklace = $35.65.

State tax charges sale tax = 8%.

Now, to find the sales tax paid on the gifts.

So, adding the price of the gifts:

12.45+35.65=48.10

Thus, the total amount of the gifts = $48.10.

Now, getting the sales tax the state charges:

8\%\ of\ 48.10

=\frac{8}{100}\times 48.10

=0.08\times 48.10

=3.848

<em><u>The tax nearest to cent = $3.85</u></em>

Therefore, the tax Jenna and Richie pay on the gifts is $3.85.

a rectangle swimming pool is 4 ft deep. one side of the pool is 2.5 times longer than the other. the amount of water needed to f
mojhsa [17]

Find the are of the pool by dividing the volume by the depth:

1960 / 4 = 490

The pool is 490 square feet.


Area is found by multiplying the length by the width.

Let the width = X

We are told the length is 2.5X ( 2.5 times longer)


So we now have 2.5x * x = 490


2.5x * x = 2.5x^2


Now we have 2.5x^2 = 490


Divide both sides by 2.5:

x^2 = 490/2.5

x^2 = 196

find X by taking the square root of 196:

x = √196

x = 14


The width is 14 feet

The length is 2.5 * 14 = 35 feet

6. A pizza's original price is $11. It is on sale for $9.25. What percent off is it?
wolverine [178]

Solution:

<u>We know that:</u>

Original \ price = \$11

Sale \ price = \$9.25

\frac{9.25}{11} + \frac{1.75}{11} =100\%

<u>Simplify the equation to find the percent off:</u>

\frac{9.25}{11} + \frac{1.75}{11} =100\%

84\% + \bold{16\%} = 100\% \space\ \space\ \space\ \ \ \ \ [Rounded]

This means that the <u>original price</u> has decreased about 16%.

Firewood can be sold in cords. the wood is cut into equal lengths and stacked evenly in a rack. which geometric shape can be use
Nadya [2.5K]

To estimate the volume of the chord of wood, since the wood exists cut into equal lengths and stacked evenly in a rack then we can use a cylinder as a model.

<h3>What is a cylinder?</h3>

In mathematics, a cylinder exists as a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. These bases exist normally circular (like a circle) and the center of the two bases exists joined by a line segment, which exists named the axis.

A cylinder exists as a closed solid that contains two parallel circular bases joined by a curved surface.

To calculate the volume of the chord of wood, since the wood exists cut into equal lengths and stacked evenly in a rack then we can use a cylinder as a model.
