Answer: the cube root of 512 is 8.

Step-by-step explanation:

First divide 512 and take the least factors as I have shown,

512= 2×2×2×2×2×2×2×2×2

Now, make the triple twins of these factors,

(2×2×2)(2×2×2)(2×2×2)

Now, take one number from each pair and multiply them,

2×2×2=8

Therefore, the answer of the cube root of 512 is 8.

Am I right ? Because I need help with this please thanks.

to find the hypotenuse (or the ramp in question 4) you can use the equation

$a^{2} +b^{2} =c^{2}$

with a and b being the 3 feet and 9 feet and c being the unknown (ramp).

So if you plug 3 and 9 into the equation, it looks like this.

$3^{2} +9^{2} =c^{2}$

then square them.

$9+81=c^{2}$

simplify.

$90=c^{2}$

take the square root of both sides.

$\sqrt{90} = c$

$\sqrt{90}$ is approx. 9.5 so the answer would be H.

The ratio x:y is equal to 2:3 express x in terms of y

choli [55]

Answer:

x = $\frac{2}{3}$ y

Step-by-step explanation:

Given x : y = 2 : 3

Express the ratios as a fraction, that is

$\frac{x}{y}$ = $\frac{2}{3}$ ( cross- multiply )

3x = 2y ( divide both sides by 3 )

x = $\frac{2}{3}$ y
