Step-by-step explanation:

Simplify the expressions

2 {}^{3}  - 2 {}^{1}  = 2 {}^{3}  - 2 = 8 - 2 = 6

2 + 3 = 5

{3}^{2}  = 9

So the expressions from least to greatest is

2 {}^{1}  + 3 {}^{1}  < 2 {}^{3}  - 2 {}^{1}  < 3 {}^{2}

Answer:

2^{1} + 3^{1}, 2^{3} - 2^{1}, 3^{2}

Step-by-step explanation:

3^{2} = 9

2^{3} - 2^{1} = 6

2^{1} + 3^{1} = 5

Answer:

w=15

Step-by-step explanation:

-24=-3w+21

We move all terms to the left:

-24-(-3w+21)=0

We get rid of parentheses

3w-21-24=0

We add all the numbers together, and all the variables

3w-45=0

We move all terms containing w to the left, all other terms to the right

3w=45

w=45/3

w=15

Max built a rectangular Prism and a rectangular Pyramid using beach sand. The prism and the pyramid have the same base area and
vova2212 [387]

Answer:

Three times

Step-by-step explanation:

Given

Figures: Rectangular Prism and Rectangular Pyramid

Let the dimension of the prism be:

l = length

w = width

h = height

Amount of sand used is the volume (V1) and it is calculated using;

V_1 = l * w * h

V_1 = lw h

Since the pyramid has the same base area and height as the prism, the its dimension would be:

l = length

w = width

h = height

Amount of sand used is the volume (V2) and it is calculated using;

V_2 = \frac{1}{3}*(lwh)

So, we have:

V_1 = lw h

V_2 = \frac{1}{3}*(lwh)

Substitute lwh for V1 in the second equation

V_2 = \frac{1}{3}V_1

Multiply both sides by 3

3 * V_2 = \frac{1}{3}V_1 * 3

3 * V_2 = V_1

Reorder

V_1 = 3 * V_2

V_1 = 3 V_2

<em>Hence, the amount of sand used in building the prism is three times the amount of sand used in building the pyramid</em>
