we know that

the volume of a solid oblique pyramid is equal to

V=\frac{1}{3}*B*h

where

B is the area of the base

h is the height of the pyramid

in this problem we have that

B is a square

B=b^{2}

where

<u>b=x\ cm</u>

so

B=x^{2}\ cm^{2}

h=(x+2)\ cm

substitute in the formula of volume

V=\frac{1}{3}*x^{2}*(x+2)\\ \\V=\frac{1}{3}*[x^{3} +2x^{2}]\ cm^{3}

therefore

<u>the answer is</u>

V=\frac{1}{3}*[x^{3} +2x^{2}]\ cm^{3}

In a recent year, certain colleges and universities received about $268 million in aid. Ten years later, they received about $94
topjm [15]
D) 65% decrease. 

I worked it out by: 268 mill - 94 mill (calculating the difference in money) 
then divided that by the original 268 mill, to finally get 0.64925.... 

And since the money is decreasing, it is a 65% decrease. 

Hope this helps, and I think it should be right - but maybe double check in case :)

ArbitrLikvidat [17]

Answer:

32.9 inches

Step-by-step explanation:

this can be solved using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base = 49

c =  hypotenuse = diagonal = 59

l² + 49² = 59²

l² = 59² - 49²

3481 - 2401 = 1080

find the square root
