Answer:

  • $8.80
  • 40%

Step-by-step explanation:

The amount of the discount is the difference between the original price and the discounted price. That was ...

  $22.00 -13.20 = $8.80

The percentage of the discount is the ratio of the amount of the discount to the original price. That was ...

  8.80/22.00 × 100% = 40%

The price was discounted $8.80. That was a 40% discount.

A portable fuel tank used to transport gasoline is in the shape of a rectangular prism. The tank is 5 feet longer than it is wid
erastovalidia [21]

The equation represents the volume of the portable fuel tank in terms of width (w) is w³ + 34w² + 145w - 33488 = 0.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A portable fuel tank used to transport gasoline is in the shape of a rectangular prism.

The tank is 5 feet longer than it is wide and 29 feet deeper than it is wide.

The volume of the tank is 33,488 cubic feet.

Let the width of the rectangular prism be w. Then we have

length = w + 5

height = w + 29

Then the volume is given as

Volume = l × w × h

33488 = (w + 5) (w) (w + 29)

Then we have

\begin{aligned} \rm w^3 + 5w^2 + 29w^2 + 145w &=33488 \\\\\rm w^3 + 34w^2 + 145w - 33488 &= 0\\\\\rm (w - 23)(2w+57)(2w + 57) &= 0\\\\\rm w &= 23, -28.5, -28.5 \end{aligned}

Solve for x<br> Y= x-v/b
andrey2020 [161]

Answer:

x=y+v/b

Step-by-step explanation:

So first you have y=x-v/b. You want to isolate x, so subtract x from both sides. You'll get -x+y=-v/b. Next, you're going to want to subtract y to further isolate x now that it's on the left side. Now you'll have -x=-y-v/b. But you don't want x to be negative, so you can divide both sides by -1 to make x positive. Now you'll have x=y+v/b.
