Answer:

V= 2*4*5

Step-by-step explanation:

The formula for a rectangular prism is V=w*h*l so substituting:

width = 4 cm

length = 5 cm

height = 2 cm

So the equation would be V=2*4*5 and the volume would be V=40.

Answer:

V= 2 times 4 times 5

Step-by-step explanation:

In order to calculate the volume of a figure u must calculate lwh or length times width times height. In this case length is 5 width is 4 and height is 2. This can be plugged in and becomes 2 times 4 times 5.

What is 4.2X-1.4Y=2.1-2X
enot [183]

4.2x - 1.4y = 2.1 - 2x

Subtract 4.2x

-1.4y = 2.1 - 6.2x

Divide by -1.4

y = -3/2 + 9/2x

Answer: y = 9/2x - 3/2

Answer:

Sides in descending order:  YZ > ZX > XY

Step-by-step explanation:

Sum of all angles of triangle = 180

    104 +52 +  ∠Z = 180

            156 + ∠Z = 180

                      ∠Z = 180 - 156

                      Z = 24

The sides opposite to the biggest is the longest side.

Angles in descending order: ∠X  >  ∠Y >  ∠Z

<h3>Sides in descending order:  YZ > ZX > XY</h3>

Find the lengths the missing side

Answer:

  • Long leg = 10√3
  • Short leg = 10
  • Hypotenuse = 20

Step-by-step explanation:

<u>Concept: </u>

Here, we need to know the idea of a special triangle 30-60-90.

A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist.

The ratio between the corresponding side of each angle is 1 : √3 : 2

If you are still confused, please refer to the attachment below for a graphical explanation.

<u>Solve:</u>

30-60-90 ⇔ 1 : √3 : 2

Given the side corresponding to 90° is 20

30° : 90° = 1 : 2

30° : 20 = 1 : 2

30° = 10

30° : 60° = 1 : √3

10 : 60° = 1 : √3

60° = 10√3

Hope this helps!! :)

Which expression is equivalent to 1/4 − 16?<br><br> A) 1/4(n − 64)<br> B) 4(n − 4)<br> C)4(n − 64)
Elza [17]
The answer is A.) 1/4(n-64) because if you distribute the 1/4 onto the parentheses it becomes n/4 - 16 which is equivalent to 1/4 - 16 if n were to equal 1.
