Answer:
The value of ![B (base\ area) = 27m^2](https://tex.z-dn.net/?f=B%20%28base%5C%20area%29%20%3D%2027m%5E2)
Step-by-step explanation:
Let's recall the the formula for volume of a pyramid.
Volume of a Pyramid
....equation ![(1)](https://tex.z-dn.net/?f=%281%29)
where
and ![H=height\ (m)](https://tex.z-dn.net/?f=H%3Dheight%5C%20%28m%29)
Now we have been given the values of
and
and have to find the value of ![B](https://tex.z-dn.net/?f=B)
Plugging the values of
and
in equation ![(1)](https://tex.z-dn.net/?f=%281%29)
![B=\frac{3\times V}{H}= \frac{3 \times 81}{9} = 27\ m^2](https://tex.z-dn.net/?f=B%3D%5Cfrac%7B3%5Ctimes%20V%7D%7BH%7D%3D%20%5Cfrac%7B3%20%5Ctimes%2081%7D%7B9%7D%20%3D%2027%5C%20m%5E2)
Now we can also check our previous results.
![V = \frac{24\times 7}{3}=8 \times 7 =56\ m^3](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B24%5Ctimes%207%7D%7B3%7D%3D8%20%5Ctimes%207%20%3D56%5C%20m%5E3)
So, our final answer is ![27\ m^2](https://tex.z-dn.net/?f=27%5C%20m%5E2)
Answer:
a is the answer because I just did that question and got 100 percent.
Answer:
16x+29
Step-by-step explanation:
-5(2x-3) x 2+4x-1
-10(2x-3) + 4x-1
-20x + 30+4x -1
Answer: B
Step-by-step explanation:
They've given you two functions f(x) = x^2 + 1 and g(x) = 3x +1 And they are you to find 2 * f(4) then g(x) is not needed so input in 4 for the function f(x) and multiply the output by 2.
F(4) = 4^2 + 1
F(4) = 16 +1
f(4) = 17
17 * 2 = 34
