Which is greater: 25% of 15 or 15% of 25? Explain your reasoning using mathematical evidence or visual models.
15% of 25 is the greatest of the two.
Answer:
25% of 15 is 3.75
15% of 25 is also 3.75
15 - 3.75 = 11.25
25 - 3.75 =21.25
Compare and then determine.
11.25 < 21.25
Answer: 25% x 15=25/100 x 15=.25 x 15=3.75
15% x 25=15/100 x 25=.15 x 25=3.75
Now you can clearly see that they are the same.

Each person in a group buys a movie ticket, a drink, and a popcorn. How much does the group pay when there are 5 people in the group?
Answer: $55.00
Step-by-step explanation:
5.75 x 5 = 28.75
2.00 x 5 = 10.00
3.25 x 5 = 16.25
28.75 + 10.00 + 16.25 = 50.00

The cost of cellular service is proportional to the number of minutes provided per month. It does not cost anything when no minutes are used. What does the ordered pair (400, 120) represent in the context of the situation?
A. It represents the cost of the plan if 400 minutes are used.
B. It represents the cost of the plan if 120 minutes are used.
C. It represents the number of minutes used in a month.
D. It does not represent anything since the point is not on the line.
PLEASE EXPLAIN YOUR ANSWER!
Answer:
A. It represents the cost of the plan if 400 minutes are used.
Step-by-step explanation:
It's A. because on the graph it shows that 400 is on the minute line and the 120 is most likely the cost.
I think.
Answer:
the answer is a
Step-by-step explanation:
In this case the 400 is an x value representing the amount of minutes and 120 is a y value representing the cost. The 120 is dependent on the 400 proving that the answer is a. I hope that helped :))
2. What is the surface area of the ball shown?
Use 22/7 for pi and round to the nearest
whole number.
Radius is 9 centimeters.
Answer:
1018
Step-by-step explanation:
Surface area of a sphere is [tex]4\pi r^{2}[/tex]
So, for this question [tex]\pi[/tex] is equal to 22/7
Therefore, 4 multiply 22/7 multiply [tex]9^{2}[/tex]
Answer= 1018.285714
Answer to the nearest whole number = 1018

Answer:
The first question is 699.
The second question is 82.875.
Step-by-step explanation:
To find the are of the floor, we would take the volume formula for the rectangular prism and do it reversed.
V = l*w*h
2,097 = l*w*3
Divied by 3
699 = l*w
Since the area of a floor is l*w, we have found the area of the floor already.
699 feet^2
8 1/2 is 8.5. 3 1/4 is 3.25 To find the volume of a rectangular prism, it is l*w*h
3*8.5*3.25 = 82.875
Answer:
Area of floor= 699 sq ft
Volume of prism = 82 7/8 cubic ft.
Step-by-step explanation:
QUESTION 1
Given:
Volume of rectangular storage room = 2097 ft³
hieght of the storage room= 3ft
To find:
The area of rectangular floor = ?
Solution:
[tex]Volume \: of \: room = Area \: of \: floor \times height \: of \: room \\ 2097 = Area \: of \: floor \times 3 \\ Area \: of \: floor = \frac{2097}{3} \frac{ {ft}^{3} }{ft} \\ Area \: of \: floor = \cancel\frac{2097}{3} \cancel\frac{ {ft}^{3} }{ft} = 699 \: {ft}^{2} \\ \fbox{Area \: of \: floor = \: 699 \: sq.ft. }[/tex]
QUESTION 2
Given:
Length of rectangular prism l = 3 ft
width of rectangular prism w= 3 1/4 ft
Height of rectangular prism h= 8 1/2 ft
To find:
Volume of rectangular prism =?
Solution:
[tex]Volume \: of \: rectangular \: prism= l \times w \times h \\ Volume \: of \: rectangular \: prism = 3 \times (3 \frac{1}{4} ) \times (8 \frac{1}{2} ) \\ Volume \: of \: rectangular \: prism = 3 \times ( \frac{4 \times 3 + 1}{4} ) \times \frac{8 \times 2 + 1}{2} \\ Volume \: of \: rectangular \: prism = 3 \times \frac{13}{4} \times \frac{17}{2} \\ Volume \: of \: rectangular \: prism = \frac{663}{8} \\Volume \: of \: rectangular \: prism = 82 \frac{7}{8} \: cubic \: ft[/tex]

Explain how you would use estimation to help solve this problem. Be sure to include the number sentence you would use to solve the problem.
51 + N = 106
Answer:
N=55
Step-by-step explanation:
If this is just finding what N is equal to, you can subtract 51 from 106 to get 55, and if you want to make sure it's correct, you can add 51 and 55 together to get 106

Solve the system of equations by substitution
Answer:
x = 4
y = 30
Step-by-step explanation:
Since y = 8x - 2, substitute into 2nd equationThis gives you 3x + 8x - 2 = 42Add 2 to both sides11x = 44Divide both sides by 11x = 4Put this value into either equationI choose the first oney = 8x - 2 = 8 × 4 - 2 = 32 - 2 = 30Answer:
x=4
y=30
Step-by-step explanation:
First re-write the system like this:
[tex] - 8x + y = - 2 \\ 3x + y = 42[/tex]
Now substitute them together:
[tex] - 11x = - 44[/tex]
So
[tex]x = 4[/tex]
put x=4 in one of the equations
[tex]3(4) + y = 42 \\ \\ y = 30[/tex]
so
x=4
y=30

Write (5x-2)^2 as a trinomial in expanded form.
Answer:
25x^2 - 20x + 4
Hey there!
(5x - 2)^2
= (5x - 2)(5x - 2)
= 5x(5x) + 5x(-2) - 2(5x) - 2(-2)
= 25x^2 - 10x - 10x + 4
COMBINE the LIKE TERMS
= 25x^2 - 20x + 4
Therefore, your answer is:
25x^2 - 20x + 4

Jenna is having a private party at the bowling alley. The party costs $100 plus $5 per person.
Which expression can Jenna use to figure out the total amount she owes the bowling alley?
Answer: the answer should be option a. 100+5x because lets say for example that we replace x with 20 persons and that would be 100 if you multiply it but then you add 100+100= 200 dollars the total amount she owes to the bowling alley so a is the answer and hope is right and thank you so much for helping you today.

Estimate the solution of the system of equations. Write the answer as an ordered pair.
Answer:
Solution of the given system of equations is (1, 2.5)
Step-by-step explanation:
From the graph attached,
Two intersecting lines represent the system of equations.
And the solution of the system of equations is a common point where these lines intersect.

What is the mean absolute deviation of the data set shown?
A. 2
B. 4
C. 8
D. 152
Answer:
8
Step-by-step explanation:
which statement is true? a the value of 8,590-4,586 is half the value of 2 x {8,590-4,856} b the value of 2,674 x 5,480 + 5 is 5 times the value of 2,674 + 5,480 c the value of 6,432 x {1,860-6} is 6 less than the value of 6,432 x 1,860 d the value of 2,876 x {9,280 + 8} is 8 more than the value of 2,876 x 9,280
Answer:
The correct answer is a
Step-by-step explanation:
The correct answer is a because 8590-4586=4004 whereas 2×{8590-4856}=8008
in which 4004 is clearly the half of 8008 which proves the statement correct
