The formula of the volume of a pyramid is 1/3BH, where B represents the area of the base of the pyramid and H represents the hei

ght of the pyramid. The volume of pyramid A is 3 times the volume of pyramid B. Is the area of the base of Pyramid A greater, equal, or less that the area of the base of Pyramid B?

Answer:

It depends on the relation between the heights  of both pyramids

Step-by-step explanation:

We know the volume of a pyramid of base b and height h is

V=\frac{1}{3}bh

If the volume of the pyramid A is 3 times the volume of the pyramid B, then

\frac{1}{3}b_ah_a=3*\frac{1}{3}b_bh_b=b_bh_b

Which means

b_ah_a=3*b_bh_b

If we knew both heights are the same, we could conclude that

b_a=3*b_b

In which case the base of the pyramid A would be greater than the other base

But if, for example, the height of the pyramid A is 3 times the height of the other height, then

3*b_a=3*b_b=>b_a=b_b

Both bases would be the same.

If we choose that  

h_a >3*h_b

it would mean

b_a

In which case the base of the pyramid A would be less than the other base

So the answer entirely depends on the relation between the heights of both pyramids

Vlad1618 [11]

Answer:

D. y = 4x

Step-by-step explanation:

y = 4x

Plug in The point (-1,-4) into the equation

when x = -1, y = 4(-1) = -4

So (-1,-4) is the solution of y = 4x

Clementine and Jake make cookies for the school bake sale. Clementine baked 72 cookies. Jake baked twice as many as Clementine.
Mariulka [41]

Answer:

The total number of cookies they baked altogether is 216 cookies

Step-by-step explanation:

Here, we want to know the number of cookies that they baked together

From the question, we are told that Clementine baked 72 cookies while Jake baked twice as much

what this mean is that the number of cookies baked by Jake will be (2 * 72) = 144 cookies

Thus, the total number of cookies baked by the two of them will be;

72 + 144 = 216 cookies

The graph of g(x) goes through the point (-4, 1) and is parallel to h(x) = 5x - 2 points
vesna_86 [32]

Answer:

g(x)=5x+21

Step-by-step explanation:

The slope of g(x) is 5 because the slope of h(x) is 5 and g is parallel to h.

In point-slope form:

g(x)-1=5(x+4)

Rearranging for slope intercept form:

g(x)-1=5x+20\\g(x)=5x+21
