There is no picture of the face and the numbers.

It’s 45 degrees; since the line is intersecting 2 parallel lines, the angles are the same. similarly, the angle to the right of “angle 2” would be 135 degrees

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

zysi [14]

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

Helena uses a mixture of compost and topsoil in her garden. She purchased a total of 10 cubic yards of compost and topsoil for $

Annette [7]

Let C be the amount of compost

T be the amount of topsoil

Each compost cost = $25

Cost of C compost = 25C

Each topsoil cost = $15

Cost of T topsoil = 15T

Amount of compost + amount of topsoil = 10

C + T = 10 -------> Equation 1

cost of C compost + cost of T topsoil = 180

25C + 15T = 180 --------> equation 2

Solve the first equation for C

C + T = 10

C = 10 - T

Now plug it in second equation

25C + 15T = 180

25 ( 10 - T) +15T = 180

250 - 25T + 15T = 180 (combine like terms)

250 - 10 T = 180 (Subtract 250 on both sides)

-10T = 180 - 250

-10T = -70 ( divide by -10 on both sides)

T = 7

She purchased 7 cubic yards of topsoil .
