The ratio of volumes is equal to the ratio of the cubes of the scale factor. Thus,
Volume ratio:
6³ : 7³
216 : 343

Answer:

The ratio of their volumes is equal to \frac{216}{343}  

Step-by-step explanation:

we know that

If two solids are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z-----> the scale factor

x/y----> the ratio of its volumes

so

z^{3}=\frac{x}{y}

we have

z=\frac{6}{7}

substitute

(\frac{6}{7})^{3}=\frac{x}{y}

(\frac{216}{343})=\frac{x}{y}

rewrite

\frac{x}{y}=(\frac{216}{343}) -----> the fraction is irreducible

Do these side lengths make a right triangle? 5, 12, 13
lorasvet [3.4K]

Answer:

This is a right triangle

Step-by-step explanation:

We will use the Pythagorean theorem

a^2 + b^2 = c^2

If this is true it is a right triangle

5^2 + 12^2 = 13^2

25+144 = 169

169 =169

This is true so this is a right triangle
