Answer:

\boxed {\tt 6 \ centimeters}

Step-by-step explanation:

The volume of a cube can be found using the following formula:

v=s^3

where s is the side length, or edge.

We know the volume is 216 cubic inches. We can substitute 216 cm³ in for v, the volume.

216 \ cm^3 = s^3

We want to find the side length. Therefore, we must isolate the variable, s.

s is being cubed. The inverse of a cube is the cube root. Take the cube root of both sides of the equation.

\sqrt[3]{216 \ cm^3} =\sqrt[3]{s^3}

\sqrt[3]{216 \ cm^3} =s

6 \ cm=s

The length of each edge of the cube is 6 centimeters.

Volume of a cube = (edge)^3

In this problem,

Volume = 216in^2

Edge = ?

Let's plug our values into the formula above.

216in^3 = (edge)^3

Take the cbrt of both sides.

6in = edge

The length of each edge = 6in

Which describes the correct procedure when converting a number from scientific notation to standard notation if the power of 10
jenyasd209 [6]

Answer:

A. Move the decimal point to the left

Step-by-step explanation:

Given that:

The scientific notation = 10⁻¹⁰

Let recall;

That the standard notation usually took the form of an inverse:

For example;

Let say 10⁻¹ will be \dfrac{1}{10} in scientific notation;

SO, \dfrac{1}{10} = 0.1

Now; we are given 10⁻¹⁰ as a scientific notation,

To standard notation, we get:

10^{-10} = \dfrac{1}{100}

= 0.01

Thus, it is true to say that the decimal point will be moved to the left side when converting a number from scientific notation to standard notation if the power of 10 is  -10.

1. The variable that was unknown x amount of cars washed.

2.The equation I used was 110-50=15x

3. To solve this you subtract the 50$ from 110$ you get sixty dollars you do that to take out what he earned for his allowance. Then your equation is 60=15x so you divide each side by 15 and when you do that x=4
