Answer:

width = 12.5

Step-by-step explanation:

rectangular volume = height * width * length

1200 = 4 * w * (20 + 4)

1200 = 4 * w * 24

1200 = 96w

12.5=w

NO LINK SPAM OR REPORT: Tell whether x and y show direct variation. Explain your reasoning. If so, find k.
sergeinik [125]

Answer:

2. yes; the equation can be written as y = kx; k = 1

Step-by-step explanation:

x-y = 0

That means x and y have to be the same value.

If you multiply a number by 1, you get the same thing.

If you multiply x by one, you get y (the same value).

Hope this helps!

Camille is working in craft class to create new pillows for her room. Each pillow will be made from exactly 36 in2 of material.
Ann [662]

The best design for Camille is the one in which the area matches the total of material she wants to use for each pillow.

<h3>What should Camille consider for her design?</h3>

Camille's main restriction is the material per pillow since she needs every pillow to use only 36 inches of material. Due to this, she needs to make sure the design meets this requirement.

<h3>How to determine how much material each design requires?</h3>

The best method for this is to calculate the area of the design by using the sides. Here are the most common formulas:

  • Triangular design: Base x height/ 2
  • Squared or rectangular design: side x side
  • Circular design: A = π r²

Based on this, the best design is the one that adjusts to the material available.

Note: This question is incomplete because there is no information about the designs; due to this, I answered it based on general knowledge.

Karissa earns $200 per week plus $25 per item she sells. What is the equation that models the relationship between her pay per w
Digiron [165]
Let p = her pay per week.

<span>"Karissa earns $200 per week plus $25 per item she sells."

She earns a fixed amount of $200 per week no matter how much she sells.
Then she earns an additional variable amount that depends on the number of items she sells. It is $25 per item.

p = fixed amount + variable amount

The variable amount is:
If she sells 1 item, she earns 25 * 1
If she sells 2 items, she earns 25 * 2
If she sells 3 items, she earns 25 * 3
If she sells n items, she earns 25 * n
The variable amount she earns is 25n, where n is the number of items she sells.

</span>
<span>p = fixed amount + variable amount

p = 200 + 25n
