17 will represent the batches of purple paint he wanted to make. It also represents the number of cup needed for each blue and red paint.

Step-by-step explanation:

Hence, [tex]17[/tex] represents the number of cups required for the blue and red paint and it also represent the batches of purple paint he wants to do.

What is the equation?

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Here given that,

To make the perfect purple hue, the artist used cup of blue paint per batch and cup of red paint per batch. He wanted to make [tex]17[/tex] batches of purple paint.

Hence, [tex]17[/tex] represents the number of cups required for the blue and red paint and it also represent the batches of purple paint he wants to do.

Step-by-step explanation:

ahh this is a really tough one  :D  Does this happen to be an AP math class,  Pineapple    .. you are in advanced math :O.... good for you  :)

sooo what can we set equal

note the lines  have the same lenght, therefore the arc length will also be the same,  then they give us the other two lengths to make the entire circle , yay

so then just set all the arc lengths equal to 360 °

(3x+ 30) + (3x + 30 ) + 2x + 4x = 360  ( put like terms together )

12x +  60 = 360    ( subtract 60 from both sides )

12x = 300   ( divide both side by 12 )

x = 25

nice we now know X  :)

Final Price = 54.99 - 13.7475

Final Price = $41.24

Answer:

The supplement of 61° is 119°

Step-by-step explanation:

180 - 61 = 119° The supplement of 61° is 119°

The measure of the angle is 61 degrees

To determine the measure of the angle, we need to know the following;

From the information given, we have that;

The measure of an angle is 119°'

This is represented as;

119 + x = 180

collect the like terms, we get;

x = 180 -119

subtract the values, we have;

x = 61 degrees

Answer:

f(x)=x+2

Step-by-step explanation:

Pick any two points from the question and plug them into the equation y2-y1/x2-x1. In this case, I picked (0,2) and (1,3). Therefore, the equation will be   3-2/1-0. Simplify this to get 1/1 which is equal to 1. Therefore, the slope is equal to 1. Then pick a point and plug it into the point  slope form equation which is y-y1=m(x-x1) where m is the slope. In this case, I picked (0,2). Therefore, the equation will be y-2=(x-0). Simplify this to get y-2=x. You want to isolate y so you have to add 2 to both sides. This will make the equation y=x+2 which is the answer. Therefore, the answer is y=x+2 or f(x)=x+2.

Answer:

1.344

Step-by-step explanation:

Given that:

n=49,σ = 4.8

Zcritical = 95%

Using the relation :

Margin of Error = Zcritical * sqrt(σ² / n)

Zcritical at 95% = 1.96

Margin of Error = 1.96 * sqrt(4.8² / 49)

Margin of Error = 1.96 * (4.8 / 7)

Margin of Error = 1.96 * 0.6857142

Margin of Error = 1.344

A stock’s value in dollars changed by -5.75 on Monday and +3.25 on Tuesday. Which  statement correctly compares the changes in the stock’s value?

A. The value changed more on Monday because |-5.75| greater than |3.25|.

B. The value changed more on Monday because -5.75 less than 3.25.

C. The value changed more on Tuesday because +3.25 greater than 0.

D. The value changed more on Tuesday because 3.25 greater than. 25.75.

Answer:

A. The value changed more on Monday because |-5.75| greater than |3.25|.

Step-by-step explanation:

Given

[tex]Monday = -5.75[/tex]

[tex]Tuesday =+3.25[/tex]

Required

Correct statement about the stock changes

First, calculate the absolute values of both changes:

[tex]Monday = |-5.75|[/tex]

[tex]Monday = 5.75[/tex]

[tex]Tuesday = |+3.25|[/tex]

[tex]Tuesday = 3.25[/tex]

Compare

[tex]5.75 > 3.25[/tex]

This implies that there were more change on Monday than Tuesday.
