Answer:
Option (1)
Step-by-step explanation:
To calculate the volume of the given pyramid,
Formula to be used,
Volume = ![\frac{1}{3}(\text{Area of the triangular base)}(\text{Height})](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%28%5Ctext%7BArea%20of%20the%20triangular%20base%29%7D%28%5Ctext%7BHeight%7D%29)
Area of the triangular base = ![\frac{1}{2}(\text{Base})(\text{Height})](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%28%5Ctext%7BBase%7D%29%28%5Ctext%7BHeight%7D%29)
= ![\frac{1}{2}(9)(15)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%289%29%2815%29)
= 67.5 cm²
Now volume of the pyramid = ![\frac{1}{3}(67.5)(32)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%2867.5%29%2832%29)
= 720 cm³
Therefore, Option (1) will be the correct option.
Given equation :−1/2 (x+2) + 112x = 3
We have -1/2 in front of parenthesis on left side .
It's better to remove fraction in an equation, in order make it easier to solve.
In order to remove 2 from denominator of 2, we need to multiply each and every term by 2.
Multiplying each term in the equation by 2, we get
2* −1/2(x+2) +2* 112x = 2*3.
On simplifying this step, we get
-1(x+2) +224x = 6.
Distributing -1 over (x+2), we get
-x -2 +224x = 6
Combining like terms on left side, -x+224x=223x
223x -2 = 6
Adding 2 on both sides, we get
223x -2+2 = 6+2
223x = 8
Dividing both sides by 223, we get
223x/223 = 8/223.
x= 8/223.
