The sales tax for an item was $36.90 and it cost $410 before tax. Find the sales tax rate. Write your answer as a percentage.

Answer:

Pizza parlor's profit = $515.344

Step-by-step explanation:

Given that:

Linear regression line for pizza parlor's profit

y = 2.009x - 37.131

x represents the number of pizzas sold

y represent the profit in dollars

Profit for 275 pizzas

Putting x = 275 in given equation

y = 2.009(275) - 37.131

y = 552.475 - 37.131

y = 515.344

Hence,

Pizza parlor's profit = $515.344

Answer:

Step-by-step explanation:

When you have a wording that matches ...

  A depends on B

It means that A is the dependent variable, and B is the independent variable.

Here, the total monthly cost depends on the number of cups purchased.

That statement tells you that "total monthly cost" is the dependent variable, and "number of cups purchased" is the independent variable (x).

The first four (4) blanks you're to fill represent two different ways of saying this same thing.

__

The equation is a mathematical expression of the way the costs add up.

  total monthly cost = (program cost) + (per-cup cost) × (number of cups)

  M(x) = 15 + 2x

Then M(13) is ...

  M(13) = 15 + 2·13 = 15 +26 = 41

So the total monthly cost for the purchase of 13 cups of coffee is $41.

Answer:

Average rate of change for given function is: -2

Step-by-step explanation:

Given function is:

[tex]f(x)=x^2-6x+8\\x_12= 1\\x_1 = 3[/tex]

In order to find the rate of change, we have to find the value of function on x1 and x2

So,

[tex]f(x_1) = (3)^2-6(3)+8 = 9-18+8 = -1\\f(x_2) = (1)^2-6(1)+8 = 1-6+8 = 3[/tex]

The formula for finding the rate of change is:

[tex]Rate\ of\ change = \frac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]

Putting the values, we get

[tex]=\frac{3-(-1)}{1-3}\\=\frac{3+1}{-2}\\=\frac{4}{-2}\\= -2[/tex]

Hence,

Average rate of change for given function is: -2

Answer:

it will increase 5 percent

Answer:

8%

Step-by-step explanation:

Given:

A line passes through the origin and the point (-2,1).

To find:

The slope of the line.

Solution:

If a line passes though two point, then the slope of the line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that a line passes through the origin, .i.e., (0,0) and the point (-2,1). So, the slope of the line is

[tex]m=\dfrac{1-0}{-2-0}[/tex]

[tex]m=\dfrac{1}{-2}[/tex]

[tex]m=-\dfrac{1}{2}[/tex]

Therefore, the slope of the line is [tex]-\dfrac{1}{2}[/tex].

Answer:

I thin B -7 cause its negative and negative goes down.

Step-by-step explanation:

Answer:

The slope would be (i believe, sorry if I am wrong)  3/-1. Rise over run.  So you would go up 3 and left 1.

Soda = 230

Popcorn = 200

Step-by-step explanation:

(4.25 x 230) + (5.50 x 200) = 2,077.50

230 + 200 = 430

Answer:

A) 13:8

b) 8:5

Step-by-step explanation:

In this question, we will be making ratios.

Ratios are represented as a:b whereas "a" and "b" represent the different scenarios.

In this question, we need to make ratio with total apples and red apples.

We will write the ratio in respective order, or from left to right in the statement.

We know that our total amount of apples is 13, so that would go on the left side of the ratio.

We need to find the amount of red apples in the basket. We already have 5 green apples, so subtract 5 from 13.

13 - 5 = 8

We have 8 red apples, so that would go on the right side of the ratio.

Your ratio should be:

13:8

In this question, we have to make a ratio of red apples to green apples.

We know that there are 8 red apples, we also know that there's 5 green apples.

With this information, we can make our ratio:

8:5

Answer:

C.x+8=3x

Simple math!

Step-by-step explanation:

Answer: x = 11

Step-by-step explanation:

same as the last question, set them as equal and solve. here's my work:

5x - 1 = 4x + 10

5x - 1 (+ 1) = 4x + 10 (+ 1)

5x = 4x + 11

5x (- 4x) = 4x (- 4x) + 11

x = 11

Answer:

Step-by-step explanation:

You divide the tickets sold and money raised and your supposed to get 5 on all of them . Answer : 5

The constant of proportionality for the sales is 1/5. Therefore, option D is the correct answer.

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".

The given table shows the amount of money raised and the number of tickets sold by each of four students.

The constant of proportionality for the sales is

Fawn: 15/85 =1/5

Ryan: 13/65 =1/5

Daisy: 9/45 =1/5

Doug: 6/30 =1/5

Therefore, option D is the correct answer.

Answer:

800 different 4 digit passwords can be the pin

Step-by-step explanation:

Since the first digit is a factor of 20, the factors of 20 are 1,2,4,5,10,20. We only need the single digit factors which are 1,2,4 and 5.

These 4 numbers can be permuted in 1 way for the first digit, so we have ⁴P₁.

For the second digit, we have 10 digits permuted in 1 way, ¹⁰P₁ and also for the third digit, we have

10 digits permuted in 1 way,  and for the last digit, which is divisible by 5, it is either a 0 or 5, so we have two digits permuted in 1 way,

So, the number of different 4 digit number that Zara'2 4-digit PIN code could be is

4 × 10 × 10 × 2 = 800 different sets of digits

Answer:

x = 7.2

Step-by-step explanation:

you can use the cos of 63 and set it equal to adjacent / hypotenuse

cos 63° =  x  

                16

.45 =  x  

         16

x = 16(.45)

x = 7.2
