Answer: 
Step-by-step explanation:
A rectangular prism is a three-dimensional solid.
A rectangular prism has six faces (each one of these faces are rectangles), eight vertices and twelve edges.
You know that this rectangular prism has 5 layers and the volume of one of these layers is 18 cubic centimeters (
).
Assuming that all these layers are equal, the volume of this rectangular prism can be calculated with:
Where 
is the volume of one layer.
Substituting, you get:
For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
We now write the expression that models the problem:
From here, we clear the value of x.
We have then:
Answer:
4/9 divided by 1/27 equals 12
The answer is b with the angles
Answer:
Step-by-step explanation:
<u>Given equation:</u>
<u>Simplify, then solve:</u>
- -11 2/3 * (-4 1/5)
- = -35/3 * (-21/5)
- =
- = 735/15
- = 49.
Your answer is A. 49.
The result of the expressionn 1/5 - 3/4 will be negative 11/20. Then the correct option is C.
<h3>What is a fraction number?</h3>
A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.
The expression is given below.
⇒ 1/5 - 3/4
⇒ (4 - 15) / 20
⇒ -11 / 20
Then the correct option is C.
