Let's divide this into two rectangle; one rectangle is 5 by 10 inches, equal to 50. The other rectangle is only 6 by 3 inches, equal to 18 inches.

The answer is 68.

Answer is 38 because 8-5 is 3x6 = 18 + 10-6 4x5 = 20 = 20+18 = 38

Help again. I’m really bad at this.

Given the equation of a circle in the form

$(x-x_0)^2+(y-y_0)^2=r^2$

You have that $(x_0,y_0)$ is the center, and $r$ is the radius.

So, in your case, the center is $(-9,6)$ and the radius is 5.

Answer:

12862.83cm³

Step-by-step explanation:

Volume of the Box: [L×W×H] or [30x30x30] or [27000cm³]

Volume of the Sphere: [ $\frac{4}{3}\pi r^{3}$ ] ( $\pi$ =pi=3.14) (r=radius=15) or [ $\frac{4}{3}$ ×3.14×3375] or [14137.17cm³]

Volume of the empty space: 27000cm³-14137.17cm³=12862.83cm³

Btw there are online tools to help you find the volume of a sphere (just use it after you understand the equation)

Hope I helped!

What is the answer to 8x^3+125 by factoring the perfect cube?

expeople1 [14]

Answer:

$\large\boxed{8x^3+125=(2x+5)(4x^2-10x+25)}$

Step-by-step explanation:

$8x^3+125=2^3x^3+5^3=(2x)^3+5^3\\\\\text{use}\ a^3+b^3=(a+b)(a^2-ab+b^2)\\\\=(2x+5)((2x)^2-(2x)(5)+5^2)\\\\=(2x+5)(4x^2-10x+25)$
