Total number of students = 35

Number of male students = 14

% of students that are male = $\frac{14}{35} * 100 = \frac{14}{7} * 20 = 2 * 20$ = 40 %

Cheng likes a modern lawn sculpture made of four identical solid right pyramids with square bases. He decides to create an exact

lara [203]

Answer:

d. $8\text{ ft}^3$

Step-by-step explanation:

We have been given that Cheng measures each edge of each base to be 2 feet. The height of the whole sculpture is 6 feet.

First of all, we will find height of each pyramid by dividing height of whole sculpture by 4 as:

$\frac{6\text{ ft}}{4}=1.5\text{ ft}$

We know that volume of a pyramid is equal to 1/3 of base area times height that is $V=\frac{bh}{3}$ , where b represents area of base.

$V=\frac{(2\text{ ft})^2\times\text{ 1.5 ft}}{3}=4\times 0.5\text{ ft}^3=2\text{ ft}^3$

Since volume of one pyramid is equal to 2 cubic feet, so volume of 4 pyramids will be 4 times 2 cubic feet that is 8 cubic feet.

Therefore, Cheng must purchase 8 cubic feet of material.

For f(x) = 3x+1 and g(x) = x^2-6, find (g/f)(x)

nexus9112 [7]

G/f(x) = x^2 - 6 / 3x + 1
3x + 1 = x^2 - 6
x^2 - 3x - 6 - 1 = 0
x^2 - 3x - 7 = 0
x = 4.54 , x = - 1.54

I can’t see the problem very well, but your answer should be the one with (-3/2,0) as the intersecting point on the graph.
