ANGLES IN TRIANGLES WORKSHEET
Answer:
x = 26
Step-by-step explanation:
90 + 52 + unknown angle = 180
142 + unknown angle = 180
unknown angle = 38
unknown angle + 116 + x = 180
38 + 116 + x = 180
154 + x = 180
x = 26

There is a proportional relationship between the area of a wall and the amount of paint needed to cover it.
A. What is the constant of proportionality for that relationship? Explain.
Answer:
Constant of proportionality [tex] = \frac{1}{400} [/tex]
Step-by-step explanation:
A. The constant of proportionality can be calculated as the ratio of y to x. In this case, y = amount of paint, while x = the area of the wall
The area of the wall determines the amount of paint needed to cover the wall.
Constant of proportionality, k = y/x.
Any given pair cam be used as y and x to find k.
Thus, using (100, ¼),
[tex] k = \frac{\frac{1}{4}}{100} = \frac{1}{4}*\frac{1}{100} [/tex]
Constant of proportionality [tex] = \frac{1}{400} [/tex]
This means that as area of the wall increases, amount of paint increases and the ratio between them would always be [tex] \frac{1}{400} [/tex].

Suppose the point (x,y) is translated horizontally c units
Write down the corrdinates of the point
Answer:
If moved right it would be (x+c , y)
If moved left it would be (x-c , y)
Step-by-step explanation:
Basically, if you translate a point horizontally then the x coordinate would either increase or decrease while the y coordinate stays the same. You can represent this by x+or- c

1999 total revenue of a company from music sales and Licensing was 14.2 billion dollars. It was forecasted that this number would continue to drop until it reaches 5.3 million in 2014. Find the percent decrease in music revenue.
Answer:
62.67%
Step-by-step explanation:
Total revenue of a company from music sales is 14.2 billion dollars in 1999.
It reaches 5.3 million in 2014.
We need to find the percent decrease in music revenue. It can be given by :
[tex]\%=\dfrac{|\text{original value-decrement value}|}{\text{original value}}\times 100\\\\\%=\dfrac{|14.2-5.3|}{14.2}\times 100\\\\\%=62.67[/tex]
So, the percent decrease in music revenue is 62.67%.

Solve the rational equation 4 divided by x equals quantity 3 times x plus 2 end quantity divided by x squared, and check for extraneous solutions.
Answer:
x = 2
Step-by-step explanation:
Step 1: Write equation
[tex]\frac{4}{x}=\frac{3x+2}{x^2}[/tex]
Step 2: Solve for x
Cross multiply: [tex]4x^2=x(3x+2)[/tex]Distribute x: [tex]4x^2=3x^2+2x[/tex]Subtract 3x² on both sides: [tex]x^2=2x[/tex]Subtract 2x on both sides: [tex]x^2-2x=0[/tex]Factor: [tex]x(x-2)=0[/tex]Solve: [tex]x = 0, 2[/tex]Step 3: Check
Plug in x to verify it's a solution.
Substitute: [tex]\frac{4}{0}=\frac{3(0)+2}{0^2}[/tex]Evaluate: undef (cannot divide by 0)Substitute: [tex]\frac{4}{2}=\frac{3(2)+2}{2^2}[/tex]Evaluate: [tex]2=\frac{6+2}{4}[/tex]Evaluate: [tex]2=\frac{8}{4}[/tex]Evaluate: [tex]2=2[/tex]How do i graph y=4x + 5

Which relation is not a function?
{(1,5), (2,6), (3,6), (4,7)}
{(4,7, (2,1), (-3,6), (3,4)}
{(-1,6), (1,3), (2,5), (1,7)}
{(-1,2), (0,5), (5,0), (2,-1)}
Answer: C
Step-by-step explanation:
The X value repeats itself
Step-by-step explanation: In order for a function not to be a relation,
each x-coordinate must correspond to more than one y-coordinate.
Notice that in third relation, the 1 pairs with a 3
in one case and it pairs with a 7 in the other case.
Since each x-coordinate pairs with more than one y-coordinate,
this relation is not a function but the other ones are functions.

Suppose set A contains 336 elements and the total number elements in either set A or set B is 642. If the sets A and B have 78 elements in common, how many elements are contained in set B?
Answer:
math
Step-by-step explanation:
The dimensions of a rectangular garden are: Length (2x + 3) and the width is (3x-5) Find the value of x if the perimeter is equal to 26.
length=(2x-3)
width=(3x-5)
perimeter=26
perimeter= (2 times length) + (2 times width)
26= 2(2x-2) + 2(3x-5)
26 = 4x - 6 + 6x - 10
26 = 10x -16
26 + 16 = 10x -16 + 16
10 = 10x
10 ÷ 10 = 10x ÷ 10
1 = x
