<u>Answer:</u>

3/5

<u>Step-by-step explanation:</u>

We are to find the similarity ratio of a cube with volume  729 m^3 to a cube with volume 3375 m^3.

We know the formula for the ratio of two cubes:

\frac{V_1}{V_2} =k^3

where k is the similarity ratio of the two cubes.

Substituting the given values in the formula to find k:

k^3 = \frac {729} {3375}

k^3 = \frac {27} {125}

k^3 = (\frac {27} {125})^3

k=\frac{3}{5}

Therefore, the similarity ratio of the two cubes is 3/5.

Answer:

The similitary ratio is 3:5

Step-by-step explanation:

To answer this question let's call:

V_1 = 729\ m^3 to volume 1.

Let's call:

V_2 = 3375\ m^3 to volume 2


The relation k of simiiltud between both volumes we find dividing V_1 between V_2

\frac{V_1}{V_2} = k^3\\\\\frac{V_1}{V_2} = \frac{729m^3}{3375m^3}\\\\\frac{V_1}{V_2} = \frac{27}{125}\\\\\frac{V_1}{V_2} = \frac{3^3}{5^3}\\\\k^3 = (\frac{3}{5})^3\\\\k = \frac{3}{5}

Which can be used to expand the expression below?
KiRa [710]

Answer:

Distributive Property

Step-by-step explanation:

We have

5(3x - 6/7)

Distributive Property would work because 5 has to be mutliplied by 3x and -6/7 to rid the parenthesis and also give a final answer for the equation. Any others will lead to a wrong answer.
