Answer:
the y intercept represents the point on the y axis in which the line crosses on a graph.
The volume of the pyramid is 2496 cu.m.
<h3>What is a Pyramid ?</h3>
A pyramid is a three dimensional structure which has a polygon base and in general triangular faces which join at the top .
It is given that
A pyramid has a 4 m by 4 m square top
Height = 12 m
Base = 20 m
The volume of a square pyramid with a is given by
V = (1/2) * ( Area of base + Area of ) * height of the from the base
V = 0.5 * ( 20 *20 + 4*4 ) * 12
V = 2496 cu.m
The volume of the pyramid is 2496 cu.m.

Answer:
8 two-point shots,
4 three-point shots
Step-by-step explanation:
let 'x' = 2-pt shots
let 'y' = 3-pt shots
system of equations can be used as follows:
x + y = 12
2x + 3y = 28
if we solve for 'y' we get 'y = 12-x'
use '12-x' instead of 'y' in the equation 2x + 3y = 28 to solve for 'x':
2x + 3(12-x) = 28
2x + 36 - 3x = 28
-x + 36 = 28
-x = -8
x = 8
if x+y = 12, then y = 4
Answer:
sin(θ) =
Step-by-step explanation:
See the attachment.
We know that cosine is adjacent divided by hypotenuse. So since cos(θ) = -2/11, then the adjacent is -2 and the hypotenuse is 11.
Sine is opposite divided by hypotenuse. Find the opposite, which is the unlabelled side, by using the Pythagorean Theorem:
x =
So, sin(θ) =

Answer:
Step-by-step explanation:
A system of linear equations can help solve questions like this, that don't give "any" clue as to how many people are on either a van or a bus. Here you just need to interpret the question; at the bottom, it says that <em>x</em> represents the number of students on vans and <em>y</em> represents the number of students on a bus. In other words, for each school, the total number of students going on the field trip are the number of students on vans and the number of students on buses. Hope this helps :D
