The students in the music club sold tickets to their spring concert. The table shows the
amount of money raised and the number of tickets sold by each of four students.
What is the constant of proportionality for the sales?
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.
What is a proportional relationship?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.

There are 13 apples in a basket. 5 of these apples are green. The rest of them are red.
(a) What is the ratio of all apples in the basket to red apples?
(b) What is the ratio of red apples to green apples?
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.
(a) What is the ratio of all apples in the basket to red apples?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
(b) What is the ratio of red apples to green apples?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

Pls help and show workings
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:
number of cups purchasedtotal monthly costtotal monthly costnumber of cups purchasedM(x) = 2x +15M(13) = 4113 cups purchased in a monthhave a total monthly cost of $41Step-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.

Zara has forgotten her 4-digit PIN code.
She knows the first digit is a factor of 10 and the 4 digits make a number divisible by 5.
How many different sets of 4 digits could it be?
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
430 were sold.
4.25 for soda
5.50 for popcorn
the total is 2077.50
how many of each were sold?
Answer:
Soda = 230
Popcorn = 200

Find the slope of the graph
Answer:
[tex]-\frac43[/tex]
Step-by-step explanation:
Hello!
Slope is calculated by the formula [tex]\frac{Rise}{Run}[/tex].
Rise is the change in y between two pointsRun is the change in x between two points.The two points I'm picking is (0,0) and (3,-4).
The change in y (0 and -4) is -4.The change in x (0 and 3) is 3.Therefore, the slope is [tex]-\frac43[/tex].

Step-by-step explanation:
What is the slope of a line that passes through the origin and the point (-2,1)?
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].

Find the average rate of change
f(x)=x^2−6x+8 when x2=1 and x1=3
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:
Average rate of change for given function is: -2

Suppose the linear regression line y = 2.009x - 37.131 predicts a pizza
parlor's profits based on the number of pizzas sold. If x represents the
number of pizzas sold, and y represents the pizza parlor's profits in dollars,
about how much can the pizza parlor expect in profits if it sells 275 pizzas?
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
