The pattern is that you are dividing by 3.

Therefore, to work out the next three numbers, you need to divide the last number by 3.

So you'd do:

1/9 ÷ 3 = 1/27

1/27 ÷ 3 = 1/81

1/81 ÷ 3 = 1/243

Therefore, the next three numbers are 1/27, 1/81, and 1/243.

Which volume could belong to a cube with a side length that is an integer? Recall the formula Cube volume = s cubed. 18 cubic in

irina1246 [14]

We have been given 4 choices. We are asked to choose the volume that could belong to a cube with a side length that is an integer.

We know that volume of a cube is cube of each side length.

To solve our given problem, we will take cube root of each given value. The cube root of which value will be an integer that will be our correct choice.

A. $s^3=18$

$\sqrt[3]{s^3}=\sqrt[3]{18}$

$s=2.62074$

Since cube root of 18 is not an integer, therefore, 18 is not a correct choice.

B. $s^3=36$

$\sqrt[3]{s^3}=\sqrt[3]{36}$

$s=3.301927$

Since cube root of 36 is not an integer, therefore, 36 is not a correct choice.

C. $s^3=64$

$\sqrt[3]{s^3}=\sqrt[3]{64}$

$s=4$

Since cube root of 64 is 4 and 4 is an integer, therefore, 64 is the correct choice.

D. $s^3=100$

$\sqrt[3]{s^3}=\sqrt[3]{100}$

$s=4.641588$

Since cube root of 100 is not an integer, therefore, 100 is not a correct choice.

In the school Francisco I. Madero of Ciudad Delicias, the celebration was held for commemorate the arrival of spring, after the parade the stalls were set up of the kermesse. The first grade group bought 8 cakes and sold 3/4 of the total.

How much of the cake was not sold?

Let

x ----> number of cakes sold

y ----> number of cakes that didn't sell

we know that

The first grade group bought 8 cakes

$x+y=8$ -----> equation A
