The base of a solid right pyramid is a square with an edge length of n units. The height of the pyramid is n - 1 units.
Which expression represents the volume of the pyramid?
on(n − 1) units
o zn(n − 1)2 units
o {n?(n − 1) units 3
on(n − 1) units
(n-1)
n

These are all right answers, just pick the one that matches an answer choice

n^2 * (n-1)/3

(n^3-n^2)/3

((n-1)n^2)/3

Step-by-step explanation:

The general area for a square pyramid is base * height/3

Since we know the edge is n units, we can subsitute the base for:

n*n = n^2 = b

The height is n-1, so lets plug that into the formula too:

n^2 * (n-1)/3

Its a bit hard to tell what the answer choices are, since your formatting is a bit strange, So in the answer section, I will list a couple of different expressions that are all equal, so that I get the right answer choice included.

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
