Final answer:
Elizabeth can serve 40 people with one container of punch mix, by dividing the total ounces (640) by the size of one glass (8 ounces) to get 80 glasses, and then dividing that by 2 glasses per person.
Explanation:
To determine how many people Elizabeth can serve with one container of punch mix that makes 640 ounces of punch, we need to calculate the total number of 8-ounce glasses that can be poured from 640 ounces.
First, divide the total ounces of punch (640) by the size of one glass (8 ounces): 640 ÷ 8 = 80 glasses.Since each person will drink 2 glasses, we need to determine how many people can be served by the number of glasses. Divide the total number of glasses (80) by the number of glasses per person (2): 80 ÷ 2 = 40 people.So, Elizabeth can serve 40 people with one container of punch mix.
carlos has a string that is 24 inches long. he wants to divide it into 3 equal parts. write an equation to find how long each part will be. use ? to represent the unknow number. then solve your equation.
Final answer:
Carlos can divide his 24-inch string into 3 equal parts by solving the equation 3x = 24, which gives each part a length of 8 inches.
Explanation:
Carlos has a string that is 24 inches long and wants to divide it into 3 equal parts. To find how long each part will be, we can represent the unknown length of each part by the variable ? (which we will replace with x for the equation). The equation we can write for this scenario is 3x = 24.
To solve for x, we divide both sides of the equation by 3:
3x / 3 = 24 / 3x = 8So, each part of the string will be 8 inches long.

Sarah is keeping up with how many miles her car gets per gallon. She starts with a full tank. After 448 miles, she fills up with 14 gallons. If she plots the points (0,0) and (14,448) on a coordinate plane, what would be the y-value of the point (1,y)?
Using a linear function, it is found that the value is: y = 32.
A linear function has the following format:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change.b is the y-intercept, which is the value of x when y = 0.In this problem, when [tex]x = 0, y = 0[/tex], and thus, the y-intercept is [tex]b = 0[/tex].
Then
[tex]y = mx[/tex]
She also plots the point (14, 448), which means that when [tex]x = 14, y = 448[/tex], and this is used to find m.
[tex]14m = 448[/tex]
[tex]m = \frac{448}{14}[/tex]
[tex]m = 32[/tex]
Hence, the linear function is:
[tex]y = 32x[/tex]
Then, when x = 1, the point is (1,y), and:
[tex]y = 32(1) = 32[/tex]
The y-value is y = 32.

The number of teams Ms.Morris can make would be 5-students groups.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
We have been given that there are 25 students in Ms.Morris's class. She wants to divide the class into 3,4,or 5 equal teams with all students on a team.
If Ms. Morris wants to divide all the students in 3, 4 or 5 equal teams, then apply a division to know the number of students per group.
If she makes 3-students groups, it would be;
25/3
If she considers 4-students groups, then it would be;
25/4
Thus, it can be seen that she cannot divide a students in parts to have equal groups.
Therefore, she has to make 5-students groups,
25/5 = 5
This means that she can make groups of 5 students each, and she would have equal groups.

The store offers a 5% discount for every 50th customer who makes a purchase. If Cindy gets the 5% discount, which expression will represent Cindy’s bill?
A. 0.05 − 1.09m + 2.79n
B. 1.05 + 1.09m + 2.79n
C. 1.05(1.09m + 2.79n)
D. 0.95(1.09m + 2.79n)
The expression that will represent Cindy’s bill is 0.95(1.09m + 2.79n). Hence, the correct option is D. 0.95(1.09m + 2.79n).
What are equivalent expressions?Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
It is given that store sells 12-packs of ballpoint pens for $1.09 each.
The store also sells composition books for $2.79 each.
Cindy buys 'm' packs of ballpoint pens and 'n' composition books.
So, the equation for this becomes
1.09m + 2.79n
Cindy gets a 5% discount, so she has to pay 95% of the regular price.
Then the expression that will represent Cindy’s bill,
0.95(1.09m + 2.79n)
Hence, the correct option is D. 0.95(1.09m + 2.79n).

How many solutions will this system of equations have? y = 3.5x − 3.5 y = −3.5x + 3.5 No solution Infinite solutions One solution Two solutions\
It will not have any possible solutions
Step-by-step explanation:
this would actually have some solutions because
y=3.5x−3.5
Step: Substitute 3.5x−3.5 for y in y=−3.5x+3.5:
y=−3.5x+3.5
3.5x−3.5=−3.5x+3.5
3.5x−3.5+3.5x=−3.5x+3.5+3.5x(Add 3.5x to both sides)
7x−3.5=3.5
7x−3.5+3.5=3.5+3.5(Add 3.5 to both sides)
7x=7
7x

(Divide both sides by 7)
x=1
Step: Substitute 1 for x in y=3.5x−3.5:
y=3.5x−3.5
y=(3.5)(1)−3.5

Create two whole number division problems that have a quotient of 9 and a remainder of 5. Justify which is greater using decimal division.
Answer and explanation;
If we choose two whole numbers; 8 and 10
We want to divide certain numbers by 8 and 10 to get 9 remainder 5.
In this case; 77 divided by 8 is equal to 9 rem 5
and 95 divided by 10 is equal to 9 rem 5
To justify which is greater, we use decimal division;
= 77 divided by 8 we get 9.625 ( 77 ÷ 8 = 9.625)
and
= 95 divided by 10 is equal to 9.5 (95 ÷10 = 9.5)
Therefore; the first case is greater since 9.625 is greater than 9.5
That is; 9 rem 5 got after dividing 77 by 8 is greater than 9 rem 5 got after dividing 95 by 10.
a can of juice contains 175 calories per 2.5 servings which of the following is not an equivalent number of calories per serving
To find the equivalent number of calories per serving based on that a can of juice contains 175 calories for 2.5 servings, divide 175 by 2.5 to get 70 calories per serving. Any amount other than 70 calories per serving would not be equivalent.
Explanation:The question is asking to find an equivalent number of calories per serving based on the information that a can of juice contains 175 calories per 2.5 servings. To calculate the calories per serving, we divide the total number of calories by the number of servings, so:
Calories per serving = Total calories ÷ Number of servings = 175 calories ÷ 2.5 servings = 70 calories per serving.
Now, let's say we have several options that represent the number of calories per serving:
70 calories per serving (correct equivalent)60 calories per serving (not an equivalent)75 calories per serving (not an equivalent)80 calories per serving (not an equivalent)From this list, every option except for the first one (70 calories per serving) is not an equivalent number of calories per serving as our calculated 70 calories per serving.

Total amount is $23.25
[tex]100\% = 23.25[/tex]
⇒[tex]1\% = \frac{23.25}{100}[/tex]
⇒[tex]1\%= \frac{0.95}{8}[/tex]
⇒ [tex]15\%= 15\times \frac{0.95}{8}[/tex] ( By multiplying 15 on both sides)

using 3.14 for pi, what is the volume of the sphere to the nearest tenth
The volume of a sphere can be calculated using the formula V = (4/3)πr³, where π can be approximated as 3.14 for simpler calculations. Volume is proportional to the cube of the radius, so if the radius changes significantly, the volume adjusts correspondingly by the cube of the factor of change.
To calculate the volume of a sphere using the value 3.14 for pi, you can apply the formula V = (4/3)πr³. If the radius of the sphere is 'r', you would plug in the value of 'r' into this formula. Next, you would multiply the result by 4/3 and then by 3.14 in place of π to get the volume. It's important to note that the volume of the sphere increases proportionally to the cube of the radius, meaning if the radius changes by a factor of 10, the volume changes by a factor of 10³ or 1000.
