Answer: 1,029.819 cm³

Step-by-step explanation: In this problem, we're asked to find the volume of a brick. To find the volume of a brick, we use the formula for the volume of a rectangular prism.

To find the volume of a rectangular prism or a prism whose base is a rectangle, we use the following formula.

<em>Volume = length × width × height</em>

Since the brick has a length of 20.3 centimeters, a width of 8.9 centimeters, and a height of 5.7 centimeters, we can plug this information into the formula.

Volume = (20.3 cm) (8.9 cm) (5.7 cm)

Volume = 1,029.819

Therefore, the volume of the brick is 1,029.819 cm³.

Also, it's important to understand that we can plug any number in for the length width or height as long as it's one of the numbers given and it's not used more than once.

This is because the commutative property of multiplication tells us that changing the order of the factors doesn't change the product.

marissa [1.9K]

Answer:

Step-by-step explanation:

Part A

Cost = T - (15/100) * T

Cost = (85/100)*T

Part B

You are asked to take 15% off the cost of something. The first equation is very clear how to do that -- just take 15% of T away from T

The second part is not so obvious if you are not familiar with it, but the result will be the same.

Start with the first equation

Cost = T - (15/100) T  Change 1 T to 100 / 100

Cost = 100*T/100T - 15/100T

Cost = 85 /100 * T

Part C

Cost = Phone - 14            at Top quality.     Red in Graph below

Cost = 75/100 * Phone    at Big value.        Blue in Graph belos

The graph below is a good way to answer this. I won't solve it algebraically when the graph will give you a much better idea which phone to get.

Answer: Up to a phone cost of 55 dollars, the red phone is the better buy.

After 55$ the blue phone is better.

Try this with a couple of values for phone,

What is the volume of this rectangular
SashulF [63]
<h3>Given:</h3>
  • l= 5 meter
  • b= 4 meter
  • h= 3 meter
<h3>Note that:</h3>
  • l= length
  • b= breadth
  • h= height
<h3>To find:</h3>

The volume of the given rectangular pyramid.

<h3>Solution:</h3>

\large\boxed{Formula:V=\frac{1}{3}lbh}

First, multiply the length (5), breadth (4) and height (3).

5×4×3

= 60 \: cm

Now, divide 60 by 3.

\frac{60}{3}

\large\boxed{V= 20 \: {m}^{3}}

<u>Therefore,</u><u> </u><u>the</u><u> </u><u>volume</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>given</u><u> </u><u>rectangular</u><u> </u><u>pyramid</u><u> </u><u>is</u><u> </u><u>2</u><u>0</u><u> </u><u>cubic</u><u> </u><u>meters</u><u>.</u>
