: A coffee shop spends $408 for an order of 17 cases of paper cups. If the coffee shop adds 5 more cases of paper cups to the order, how much will the total cost be
Step-by-step explanation:
A case of paper cups costs $408 / 17 = $24.
5 more cases => 22 cases of paper cups total.
Hence the total cost will be 22 * $24 = $528.
Answer:
$528
Step-by-step explanation:
We find the unit rate of the cost per case.
$408 / 17 cases = $24/case
Each case costs $24.
Adding 5 cases to 17 cases, the order will be for 22 cases.
22 cases * $24/case = $528
Answer: $528

Which is not a function
A function is of the form [tex](x,y)[/tex]
Assume a function is:
[tex]\{(x_1,y_1),(x_2,y_2),(x_3,y_3).....,(x_n,y_n)\}[/tex]
In simple terms:
For an ordered pair to be regarded as a function, no x value must be repeated
Analyzing the options:
1. [tex]\{(-3,-1),(8,-1),(0,-5),(-9,-2)\}[/tex]
This is a function because none of the x values (-3, 8, 0 and -9) appeared more than once
2. [tex]\{(5,9),(-3,-5),(0,4),(-9,9)\}[/tex]
This is a function because none of the x values (5, -3, 0 and -9) appeared more than once
3. [tex]\{(9,0),(-5,4),(5,0),(6,3)\}[/tex]
This is a function because none of the x values (9, -5, 5 and 6) appeared more than once
4. [tex]\{(2,8),(2,1),(-9,-5),(-8,9)\}[/tex]
This is not a function because one of the x values (2) appeared more than once.

6 + 4x - 9 what is the awnser
Answer:
y = 5
Step-by-step explanation:
4×(x -3y = -6 ) ➡ 4x - 12y = -24
4x -12y - 4x +9y = 9 - 24 ➡ -3y = -15
y = 5 use this value to find x
x - 3×5 = -6

A charity organization had to sell a few tickets to their fundraiser just to cover necessary production costs after selling 10 tickets, they were still a net loss of $800 (due to the product cost). They sold each ticket for $70 let y represent the net profit (in dollars) when they have sold x tickets
Answer:
y = 70x - 1500
Step-by-step explanation:
Price per ticket = 70
Using the relation :
y = mx + c
x = number of tickets sold
When x = 10 ; y = - 800
Hence,
-800 = 70(10) + c
-800 = 700 + c
-800 - 700 = c
Hence, c = - 1500
The equation for the net profit in dollars is :
y = 70x - 1500
Hannah completed 1/2 an hour she had to complete 4 math problems she spent and equal amount on each problem how much of and hour did Hannah spend on each problem
Answer: 1/8 hours or 7.5 minutes
Step-by-step explanation:
Since Hannah spent 1/2 an hour to complete 4 math problems. We are further told that she spent an equal amount of time on each problem.
The amount of time spent on each problem will be:
= 1/2 ÷ 4
= 1/2 × 1/4
= 1/8 hours
Since 60 minutes = 1 hour
1/8 hours = 1/8 × 60 = 7.5 minutes each.

Veronica is shopping for school clothes. She wants to buy pants and shirts. The cost of her clothes can be found using the expressions 30x+ 25y where x is the number of pants and y is the number of shirts. She will also pay 8 tax. If Veronica buys eight shirts and two pairs of pants use the expression from question 4 to determine the total cost of the bill including 8% tax
Answer:
$280.80
Step-by-step explanation:
Given:
C = 30x+ 25y
Where,
C = total cost
x = number of pants
y = number of shirts.
If Veronica buys eight shirts and two pairs of pants
C = 30x + 25y
= 30(2) + 25(8)
= 60 + 200
= 260
C = $260
Sales tax rate = 8%
Amount of sales tax = 8% of $260
= 8/100 × 260
= 0.08 × 260
= $20.80
Total cost of the bill including 8% tax = $260 + $20.80
= $280.80

Step 2: Simplify
Distribute 2: 5x + 2x - 6Combine like terms: 7x - 6Combining like terms is a process where you combine the terms with the same variable and/or exponent.
Let's say that we have an expression 3p + 3q. We can't combine the like terms, because 3p and 3q have different variables.
Now, what is the distributive property?
The distributive property is a property used for multiplying a monomial by a binomial or trinomial by "distributing" the monomial. The distributive property has a formula, which is:
[tex]\sf{a(b+c)=ab+ac}[/tex]
Here, a got multiplied by b and c.
Similarly, we combine the terms:
[tex]\sf{5x+2(x-3)}[/tex]
Simplify:
[tex]\sf{5x+2x-6}[/tex]
Combine like terms:
[tex]\sf{7x-6}[/tex]
Hence, the simplified answer is 7x - 6.

Jack bought a new car. The price of the car was $18,936. He paid $3,000 upfront and got a loan for the remaining balance. If he paid the same amount each month for 4 years (at which point the car is paid off), how much was his monthly payment?
Answer:
Step-by-step explanation:
Given that:
Price of car = $18,936
Upfront paid = $3000
Time taken to pay remaining balance = 4 years
Amount paid per month if the same amount is paid per month
Remaining balance :
($18,936 - $3000) = $15,936
Number of months in 4 years = (12 * 4). = 48 months
Amount paid per month :
$15,936 / 48
= $332

A parallelogram is a quadrilateral , In which opposite sided are equal and parallel to each other.
The coordinate of point C are (a + b , c)
The coordinates of the midpoint of diagonal BD are [tex](\frac{a+b}{2},\frac{c}{2} )[/tex]
AC and BD intersect at point E with coordinates [tex](\frac{a+b}{2},\frac{c}{2} )[/tex]
By the definition of midpoint, AE ≅ CE and BE ≅ DE.
Therefore, diagonals AC and BD bisect each other.
Properties of Parallelogram shown below,
Opposites sides of a parallelogram are equal and parallel to each other. Opposite angles are equal.Diagonals of a parallelogram bisect each other. Each diagonal divides the parallelogram into two congruent triangles.Since, Diagonals of a parallelogram bisect each other. Therefore, point E is the mid point of both diagonal AC and BD.
Let us consider , coordinate of point C are (x, y)
By using mid point formula,
Coordinate of point E = [tex](\frac{x}{2},\frac{y}{2} )[/tex]
[tex](\frac{a+b}{2},\frac{c}{2} )=(\frac{x}{2},\frac{y}{2} )[/tex]
So, [tex]C(x,y)=(a+b,c)[/tex]
E is the point at which both diagonal bisect to each other. Therefore, E is the mid point of both diagonal AC and BD.
So, coordinate of point E are [tex](\frac{a+b}{2},\frac{c}{2} )[/tex]
Thus, By the definition of midpoint, AE ≅ CE and BE ≅ DE.
Therefore, diagonals AC and BD bisect each other.

A deep sea diver is at 45 feet below sea level. A helicopter is at 100 feet above sea level. What is the distance between the helicopter and deep sea diver?
Answer:
D = 55 feet
Step-by-step explanation:
Let below sea level is negative direction and above sea level is positive direction.
A deep sea diver is at 45 feet below sea level = -45 feet
A helicopter is at 100 feet above sea level = +100 feet
We need to find the distance between the helicopter and deep sea diver. It can be calculated by simply adding the above data as follows:
D = -45 +100
= 55 feet
Hence, the distance between the helicopter and deep sea diver is 55 feet.
SAT QUESTION!!!
Jayden has been reading a 275-page book for English class. On average, he has read about 10 pages in 15 minutes. With a deadline looming, Jayden realizes that he won't finish in time unless he skims through the rest of the book. If he skims the book, he can cover 15 pages in 10 minutes. If it takes Jayden 5 hours and 50 minutes to finish the book (reading and skimming combined), how many pages did Jayden have to skim through?
WITH STEPSSS
Step-by-step explanation:
Let x be the number of pages that were skimmed through.
Time taken to skim through = 10 * (x/15) = 2/3 x min.
Time taken to read through = 15 * [(275-x)/10] = 1.5(275-x) min.
We have 2/3 x + 1.5(275-x) = 350.
Therefore 412.5 - 5/6 x = 350 and x = 75.
