Students are selling raffle tickets for a school fundraiser. They collect $24 for every 10 raffle tickets they sell.
a. Suppose is the amount of money the students collect for selling raffle tickets. Write an equation that reflects the relationship between and .
b. Label and scale the axes and graph this situation with on the vertical axis and on the horizontal axis. Make sure the scale is large enough to see how much they would raise if they sell 1000 tickets. (LOOK AT THE PHOTO)
Answer:
The answer is m= 2.4r.
The equation that represents and reflects the relationship between x and y is [tex]\mathbf{y =2.4x}[/tex]
Let y represents the amount they collect, and x represents the number of raffle tickets they sell.
So, the ratio is represented as:
[tex]\mathbf{y : x =24 : 10}[/tex]
Express the ratio as fractions
[tex]\mathbf{\frac{y }{ x} =\frac{24 }{ 10}}[/tex]
Divide 24 by 10
[tex]\mathbf{\frac{y }{ x} =2.4}[/tex]
Multiply both sides by x
[tex]\mathbf{y =2.4x}[/tex]
So, the equation that represents and reflects the relationship between x and y is [tex]\mathbf{y =2.4x}[/tex]
See attachment for the graph of [tex]\mathbf{y =2.4x}[/tex]

The drama club you are part of is hosting a pancake breakfast. You are in charge of buying the sausage, which costs $5 per pound, and bacon, which costs $4 per pound. The meat budget you are given totals $500 dollars. The inequality 5x + 4y ≤ 500 represents the possible combinations of pounds of sausage (x) and bacon (y) you can buy.
Graph: graph of the inequality y is less than or equal to negative five fourths times x plus 125
Which of the following does not represent a solution to the inequality?
A.) 20 pounds of sausage and 90 pounds of bacon
B.) 40 pounds of sausage and 40 pounds of bacon
C.) 60 pounds of sausage and 80 pounds of bacon
D.) 80 pounds of sausage and 20 pounds of bacon
60 pounds of sausage and 80 pounds of bacon are not solution of inequality. Therefore, option C is the correct answer.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given that, the inequality 5x+4y≤500 represents the possible combinations of pounds of sausage (x) and bacon (y) you can buy.
The inequality reduced to y≤-5/4x+125
A) 20 pounds of sausage and 90 pounds of bacon
90≤-5/4×20+125
90≤100
B) 40 pounds of sausage and 40 pounds of bacon
40≤-5/4×40+125
40≤75
C) 60 pounds of sausage and 80 pounds of bacon
80≤-5/4×60+125
80≤50
Does not represent the solution of equation.
D) 80 pounds of sausage and 20 pounds of bacon
20≤-5/4×80+125
20≤25
Therefore, option C is the correct answer.

When is the constant of proportionality the same as the unit rate when comparing two quantities?
a.) only when the two quantities are indirectly proportional
b.) always
c.) only when the two quantities are directly proportional
d.) never
will mark if correct :)
Answer:
Sorry im, late but here is the answer!
The constant of proportionality will be the same as the unit rate when the two quantities are directly proportional thus, option (C) is correct
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Suppose a direct relationship,
x ∝ y
x = ky
x/y = k (unit rate)
Hence "The constant of proportionality will be the same as the unit rate when the two quantities are directly proportional".

A number is equal to twice a smaller number plus 3. The same number is equal to twice the sum of the smaller number and 1. How many solutions are possible for this situation?
Infinitely many solutions exist because the two situations describe the same line.
Exactly one solution exists because the situation describes two lines that have different slopes and different y-intercepts.
No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.
Exactly one solution exists because the situation describes two lines with different slopes and the same y-intercept.
if a number (lets say 'y' is that number) is equal to (I.e. y = )..mathematically
now y is equal to twice the smaller number ( lets say that the smaller number is 'x' ) plus (+) 3 . that brings us to the linear equation...
y = 2x + 3;
also the second part of the question says that the same number ( I.e. 'y' here ) is twice the sum of smaller number (I.e. '2x' here ) and 1.
which gives us 2nd equation I.e.
y = 2x + 1 ;
the question is to find the possible number of solutions for both these equation
to find solution means to find all those points or say numbers which would satisfy both these equations
now for the first equation..
lets say ( y = 5 ) this means ( 2(1) + 3 )
so the solution will be ( 1, 5)
now for the second equation..
we will proceed with whatever data we know..
I.e. we know that value of ' y ' is 5, as we assumed
putting value of y in 2 nd equation we get ( 2(2)+1 )
I.e solution will be ( 2, 5)
now what does this signify...?
it signifies that there is no such point that will satisfy both these equations simultaneously..
hence we can say that there is no solution possible to this situation.

Courtney needs to find 2,495 ➗ 48. In which place should she write the first digit of the quotient?
A ones
B tens
C hundreds
D thousands
The first digit of the quotient is written in the tens place as the quotient is 51 so, option B is correct.
What is division?It is a fundamental operation in mathematics where you divide a number into smaller parts. Division, which includes dividing a larger number into smaller groups with the same number of components, is one of the basic mathematical operations.
Given:
2,495 ÷ 48
When we divide 2495 by 48 then the quotient will be 5 then the remainder will be 9,
Again drop the number 5 the dividend will become 95, divide it by 48 then, the quotient will be 1, and it is written on the right side of the previous quotient as 51 and the remainder will be 47.
Thus, the first digit 5 is written in tens place as the number is 51.
