The volume of the triangular prism is 54 cubic units.What is the value of x?
nadezda [96]

Answer:

x=3

Step-by-step explanation:

the volume of the prism with triangular base is 54 unit³

The base is a triangle with,  base i.e 4 units  and  height i.e x units

Also,  height of the prism = 3x

So, volume of the prism is,

And

,

Area_{Triangle}=\dfrac{1}{2}\times base\times Height_{Triangle}=\dfrac{1}{2}\times 4\times x=2x\ unit^2

Then,

V_{Prism}=2x\times 3x=6x^2

As the volume is given as 54 unit³, hence

6x²=54

x²=9

x=3

NoT YellInG ThIS IS JuSt TO AtTRaCT AtTeNTiOn 50 POiNtS PLeaSE ANswER I Am NoT WasTiNg PoInTS!!! Find the range of 1 1/4, 5/8, 3
Arada [10]

Answer:

<u>Range = 1 1/4</u>

Step-by-step explanation:

Range = Maximum - Minimum

Arranging the data in ascending order :

  • <u>1/2, 5/8, 3/4, 1 1/4, 1 1/2, 1 3/4</u>

<u />

Solving for range :

  • Range = 1 3/4 - 1/2
  • Range = 1 3/4 - 2/4
  • Range = 7/4 - 2/4
  • Range = 5/4
  • <u>Range = 1 1/4</u>
