Answer

$14

Step-by-step explanation:

You divide 35 by 20 so you get the cost of each individual comic book (35/20=$1.75 each)

then you multiply 8 by $1.75 which is equal to: $14

The answer is 14 dollars during the sale.

Find the value of x

AveGali [126]

Answer:

x = 120

Step-by-step explanation:

Since they are supplementary, they add up to 180 degrees.

So, you can say x + x/2 = 180

Then, you would solve it like an algebra problem.

Multiply both sides by 2

2x + x = 360

Simplify

3x = 360

Divide both sides by 3

x = 120

How many cubes with side lengths of 1/3 cm does it take to fill the prism?

user100 [1]

Answer:

The number of cubes that fill the prism is 24

Step-by-step explanation:

Given as :

The length of cube (l) = $\frac{1}{3}$ cm

The length of prism (L) = 1 cm

The width of prism (w) = 2 $\frac{2}{3}$ = $\frac{8}{3}$ cm

The height of prism (h) = $\frac{2}{3}$ cm

Let the number of cubes that fill the prism = x

Now, Volume of cube with length (l) = l³ cm³

Or, Volume of cube with length (l) = $(\frac{1}{3})^{3}$ cm³

Or, Volume of cube with length (l) = $(\frac{1}{27})$ cm³

Again , Volume of prism = $\frac{1}{2}\times Length \times width \times height$

Or, Volume of prism = $\frac{1}{2}\times 1 \times \frac{8}{3} \times \frac{2}{3}$

Or, Volume of prism = $(\frac{8}{9})$ cm³

<u>So , The number of cubes to fill prism </u>

The number of cubes × Volume of cube = Volume of prism

Or, x × $(\frac{1}{27})$ cm³ = $(\frac{8}{9})$ cm³

or x = $\frac{8\times 27}{9}$ = 24

Hence The number of cubes which fill the prism is 24 Answer
