Answer:
V = 1/6 s^3
Step-by-step explanation:
In general the formula for the volume of a pyramid is V = (1/3) b * h
What you are given here is
B = s^2
h = (1/2) s
Putting this into the formula for the pyramid you get
V = (1/3) * s^2 * (s/2) Combine like terms (the "s"s)
V = (1/3) * (1/2) * s^3
V = 1/6 s^3
49.5 is the answer because 66% equals 2/3.
Bro- basically so the first option a- right? So a is 4-8-12-16. And B is just that times two so the third option down
You can make use of the slope-intercept form of a line which is:
y = mx + b
Substitute m and the coordinates of a point in the line to find b,
-2 = (2/5) (5) + b
b = -4
The equation is
y = (2/5) x - 4
In standard form:
(2/5)x - y = 4
2x - 5y = 4
1/(-9)^2 = 1/81 just that
