Answer:

A) 30 cubes.

B) 30 units³.

Step-by-step explanation:

A) 1. Calculate the volume of the rectangular prism, as following:

$Vr=(lenght)(width)(height)$

2. You have that:

- The length is: $1^{\frac{1}{2}}ft=1.5ft$

- The width is: $1ft$

- The heigth is: $2^{\frac{1}{2}}ft=2.5ft$

3. Substitute these values into the formula:

$Vr=(1.5ft)(1ft)(2.5ft)=3.75ft^{3}$

4. The volume of one cube is:

$Vc=side^{3}$

5. The length of one side is: $\frac{1}{2}ft=0.5ft$

6. Substitute this value into the formula:

$Vc=(0.5ft)^{3}=0.125ft^{3}$

7. The number of small cubes that can be packed in the rectangular prism is:

$cubes=\frac{Vr}{Vc}\\cubes=\frac{3.75ft^{3}}{0.125ft^{3}}\\cubes=30$

B) 1. The length, the width and the height of the rectangular prism in term of units cubes is:

$Length=\frac{1.5ft}{0.5ft}=3units$

$Width=\frac{1ft}{0.5ft}=2units$

$Heigth=\frac{2.5ft}{0.5ft}=5units$

2. Therefore, the volume of the rectagular prism in terms of the small cube and a unit cube is:

$Vr=(3units)(2units)(5units)=30units^{3}$

Alinara [238K]

The proportional relationship that represents the market that sells their carrots at a lower rate per pound is: y = 1.6x.

<h3>What is a proportional relationship?</h3>

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

From the table, the rate is:

k = $8.8/4.4 = 2.

From the market, the rate is:

k = $4.8/3 = $1.6.

Hence the equation is y = 1.6x.
