Answer:

The height of the tent = 3 feet

Step-by-step explanation:

Question

Syrus is buying a tent with the dimensions shown below. The volume inside the tent is 36 feet^3. Syrus isn't sure if the tent will be tall enough for him to sit up inside. The tent is the shape of triangular prism whose length is 6 feet and width is 4 feet. What is the height of the tent?

Given:

Length of the tent = 6 feet

Width of the tent = 4 feet

Volume of the tent = 36 $feet^3$

To find the height of the tent.

Solution:

Since the ten is in shape of triangular prism, so the volume of traingular prism is given as:

$V=\frac{1}{2}\times l\times w\times h$

where $l$ represents length, $w$ represents width and $h$ represents height of the prism.

Plugging in the know values of the dimension of the tent and the volume to find the height of the tent.

$36=\frac{1}{2}\times 6\times 4\times h$

Simplifying.

$36=12h$

Dividing both sides by 12.

$\frac{36}{12}=\frac{12h}{12}$

$3=h$

∴ $h=3$

Thus, the height of the tent = 3 feet

Equations and inequalities

DerKrebs [107]

Inequalities and equations use similar steps to solve, but inequalities give a range of numbers that can represent the variable while an equation will give a direct answer.

Example:

4+5x=24

First you would subtract 4 or add the opposite of 4 from 24.

4+5x=24
+(-4) +(-4)
—————
5x=20

Then divide each side by 5 or multiply each side by the reciprocal of 5 to isolate the variable.

1/5*5x=20*1/5 (reciprocal)
X= 4

You would use the same steps in an inequality but end up with a different sign.
