Answer:
12
Step-by-step explanation:
According to Euclidian theorem h^2 = 3*x (h : height)
36 = 3x divide both sides by 3
12 = x
Answer:
The cost of the $0.5 per cookies and $1.25 per brownie.
Option (A) is correct.
Step-by-step explanation:
Let us assume that the cost of the cookies =x
Let us assume that the cost of the brownie = y
As given
Sara is selling cookies and brownies as a fundraiser for the school band.
She charges $2.25 for two cookies and one brownie.
Than the equation becomes
2x + y = 2.25
She charges $5.75 for four cookies and three brownies.
4x + 3y = 5.75
Than two equation are
2x + y = 2.25 and 4x + 3y = 5.75
Multiply 2x + y = 2.25 by 3 and subtracted from 4x + 3y = 5.75
4x - 6x + 3y - 3y = 5.75 - 6.75
-2x = - 1
2x = 1

x = $0.5
Put in the equation 2x + y = 2.25
2 × 0.5 + y = 2.25
1 + y = 2.25
y = 2.25 - 1
y = $1.25
Therefore the cost of the $0.5 per cookies and $1.25 per brownie.
Option (A) is correct.
Answer:
0
Step-by-step explanation:
Hello, please consider the following.
For any a and b real numbers we can write.

We apply this formula two times here, as below.

We have the coefficient of 1 for
and the constant term is -1, so the sum of the coefficients is 0.
Thank you.
Answer:
<em>I've attached a picture of a unit circle with the quadrant labeled. </em>
<u>Calculate the degree of 5п 8 radians:</u>

<u>Locate the general location of 112.5° on the unit circle:</u>
It's between 120°(
) and 90°(
).
<u>Find the quadrant it lies in:</u>
Quadrant II
Points W, Y and Z form a right triangle, so we can find the length of c by using the Pythagorean theorem.
Using YZ as the base and YW as the side we get:
C = √(3^2 + 4^2)
C = √(9+16)
C = √25
C = 5 units
