The answer is b

If you go backwards on a number line, you are subtracting--which is the same as adding a negative.

Justin wants to buy a new bicycle, which costs $266.52. His parents have promised to contribute one-fourth of the cost of the bi
Oliga [24]

Answer:

$199.89

Step-by-step explanation:

The bike costs 266.52

The parents are contributing one fourth of this (1/4)

We need to find 1/4th of 266.52

Divide 266.52 by 4 to find out how much Justin's parents are contributing to the bike

The answer is 66.63

Now subtract 66.63 from 266.52

Justin has to pay a total of 199.89

A rectangular prism has a volume of 240 cubic feet. If the length is 4 feet and the width is 4 feet, what is the height of
frosja888 [35]

Answer:

Let's use the formula for the volume of a rectangular prism;

V = l · w · h

Where 'l' represents the length, 'w' stands for the width, and 'h' displays as the height. (V evidently stands for the volume)

<u>What we know:</u>

  • Volume = 240 ft
  • Length = 4 ft
  • Width = 4 ft

<u>What we need to find out:</u>

  • Height

Let's plug in what we know into the formula:

V = l · w · h

<u>240</u> = <u>4</u> · <u>4</u> · h

Now let's solve for h:-

240 = 16 · h

240 = 16h

Get rid of h's co-efficient by dividing 16 from both sides because the inverse operation of multiplication(since 16 is being multiplied by h) is division.

÷16    ÷16

Finally, you would end up with a result of:

<u>15</u> = h

Hence, the height of this prism is <u>15 feet</u>.
