Answer:

Perimeter = 4x + 18

Step-by-step explanation:

{(x + 3) + (x + 3) + [(x + 3) -x]} × 2 = (2x + 6 + 3) × 2 = 4x + 18

[(        width     ) + (  length )] × 2

Write the expression that shows “3 tunes the sixth power of 10
tiny-mole [99]

3 times the 6th power of 10

Lets step by step convert the word form to an expression

You have to multiply 3 by the 6th power of 10, so

3 * 6th power of 10

In the 6th power of 10, 10 is the base and it is to the power of 6, so it can be reworded to 10 to the 6th power

or 10^{6}

We have to multiply it by 3

So the written expression is

3 * 10^{6}

Please help me on this problem.
VashaNatasha [74]

Answer : (8,5)

Given

K(x) = 8-\sqrt[3]{x}

Now we plug in each point and check whether it satisfies our equation

(-64,12)

K(-64) = 8-\sqrt[3]{-64}= 12 so this point lie on graph

(125,3)

K(125) = 8-\sqrt[3]{125}= 3 so this point lie on graph

(343,1)

K(343) = 8-\sqrt[3]{343}= 1 so this point lie on graph

(8,5)

K(8) = 8-\sqrt[3]{8}= 6 so this point does not lie on graph because we got 6 instead of 5

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
