A pack of 50 sheets of paper costs $1.10. What is the cost per
sheet of paper? Did you multiply or divide to find your answer?
a. $0.022, divide c. $55, multiply
b. $0.022, multiply d. $55, divide
Answer: Choice A
$0.022, divide
======================================================
Work Shown:
50 sheets = 1.10 dollars
50/50 sheets = 1.10/50 dollars
1 sheet = 0.022 dollars
In the second step, I divided both sides by 50 to get the "50 sheets" to turn into "1 sheet". The result of 0.022 dollars is equivalent to 2.2 cents; so the unit cost is a little over 2 cents per sheet.

Numerele a,b,c sunt rationale si verifica egalitatea 3a+4b=c-36. Determinati cele trei numere daca a si b sunt direct proportionale cu 4 si 3,iar b si c sunt invers proportionale cu 0,24 si 0,01
Answer:
a/4 = b/3 = k
a=4k
b=3k
0.24=24/100=6/25
0.01=1/100
6b/25 = c/100 = k'
b=25k'/6=3k =>k'=18k/25
c=100k'=72k

b: The graphs will look the same
Step-by-step explanation:
a: The steps will be different, because if they use an x-y table to graph, calculating the numbers will different, because they put the negative sign in different parts of the fraction.
In reality, that won't make a difference.
The graphs will look the same regardless

Answer: 40
Step-by-step explanation:
4 x (x)/4 = 10 x 4 (4 ÷ 4 = 1, so they'll cancel out)
10 x 4 x 1 = 40
Step-by-step explanation:
so, the whole thing starts out as
x/4 = 10
the next 2 steps are written by your teacher :
multiply both sides now by 4
4 × x/4 = 10 × 4
on the left side (as your teacher stroke through)
4 / 4 = 1
leaving x all by itself.
on the right side
10 × 4 = 40
and you get
x = 40
and there is your result.

What are the characteristics of the graph of the inequality x < 4.5 ?
The ray will move to the left.
It will use a closed circle.
It will use an open circle.
The ray will move to the right.
Answer:
The ray will move to the left and it will use an open circle.
Step-by-step explanation:
The ray will move to the left because x < 4.5 is the same thing as -∞<x<4.5,
It will be a open circle because x is not less than or equal to 4.5, it is this: x is less than 4.5.

Julie sees a ride that spins 10 turns each minute. She says it will spin 40 turns in 4 minutes. Is Julie correct? Explain.
Answer:
yes
Step-by-step explanation:
1 minute = 10 turns
4 minutes = 40 turns
• This is direct proportion. As one side increases by a value so must the other. In this case 1 min has become 4 mins. This has been multiplied by 4. So 10 must be multiplied by 4 too. 4 × 10 = 40 turns.
Answer: Yes she is correct

Two bicyclists are on a 75-mile trail riding toward each other. One bicyclist begins at the 45-mile marker. The other begins at the end of the trail. The expressions shown represent the distance from the Parking Lot for each bicyclist when they meet.
Two bicycles traveling toward each other are shown. The bicycle on the left travels from a point labeled parking lot. It travels a distance represented by the expression forty-five plus ten x. The bicycle on the right travels from a point labeled 75 miles from the parking lot. It travels a distance represented by the expression seventy-five minus ten x.

Question 1: The following graph shows the number of soccer games a team won in each of their first three seasons. Explain how you could redraw the graph so that the change in wins between three seasons does not seem so great.
Question 2: Why could the mean of the data set below be misleading?
ages of teachers: 29, 38, 39, 26, 29, 29, 39, 77, 38 ,29
Answer: Question 1: For season 1 it is 1,10 for the grid and for season 2 it is 2,8 Question 2: 29, is 14 in the gap to 38 and the rest count by 2s or 10s.
and the season 3 is 3,7
See more below......
Step-by-step explanation:
Question 1: Use a coordinate grid to answer the question.
Coordinate grid is a rectangular plane where the intersection of horizontal and vertical lines forms a grid network.
Question 2: Is you count by 2s or 10s.
2s are you add 2 to get the next number.
10s are counting multiple groups of 10 in a faster way.
Therefore, Question 1 and Question 2 are correct.

Regular tickets to a concert cost $34.50, and VIP tickets cost $78.50. A total of 810 tickets were sold, and total ticket sales were $29,045. The equation 34.50r+78.50(810−r)=29,045 can be used to determine the number of regular tickets r sold to the concert. How many of each type of ticket were sold?
I need help please this is 8th grade math. Please help.
Answer:
There were 480 regular tickets and 330 VIP tickets sold
Step-by-step explanation:
because, when plugged into the equation, 480 and 330 make the equation true. The Step-by-step explanation for this is,
34.5(480)+78.5(810-480)=29,045

D. multiplication
Answer:
Subtraction
Step-by-step explanation:
Since you have 11x + 3 = 3, you need to get rid of the +3. To do that, you need to do the ooposite of what the sign says which in this case is addition. The opposite of addition is subtraction.

Describe and correct the error a student made when graphing the linear equation y = - 6.
Answer:
The error is in computing the y intercept. It should be at (0, -6) not (0, 6)
Step-by-step explanation:
The equation of the line is
[tex]-\frac{3}{4} x - 6[/tex]
y intercept is at point x = 0
When x = 0,
[tex]y = -\frac{3}{4} x - 6\\\\y = 0 - 6 \\\\y = -6[/tex]
So y intercept is at point (0, -6)
If we plot a second point 3 units down and 4 units right we should get the point 0 + 4, -6 - 3) = (4, -9)
Plugging this into the original correct equation satisfies the equation
[tex]y = -\frac{3}{4} x - 6\\\\y = -\frac{3}{4} (4) - 6 \\\\y = -3 -6 = -9 \\\\[/tex]
So we can see that the line does pass through (4, -9)

The following pie chart represents how many absences the students of Washington Middle School had during the first quarter. What percentage of the students had three or more absences during the first quarter?
Answer:
300
Step-by-step explanation:
Let the total students be x.
Students absent for two or more = 32%
(on adding percentage of both 2 and 3 or more)
32/100x = 96
X = (96*100)/32
X = 300
Akio has 27 blankets and 18 flashlights to use in emergency relief kits for communities in need. He will put the same number of blankets and the same number of flashlights in each kit. He wants to use all the blankets and flashlights. What is the greatest number of emergency relief kits Akio can make?
Answer:
6
Step-by-step explanation:
The answer Is 6
Answer:
9
Step-by-step explanation:
We can make an equation out of this
So if he has 27 blankets, and 18 flashlights, he will need to divide evenly amongst the kits.
The equation would be
z=x+y, where x is the amount of blankets, and y is the amount of flashlights.
to find this, we need to find what 27 is divisible by, and what 18 is divisible by.
27 - 27, 9 , 3, 1
18 - 18, 9, 6, 2, 3, 1
Now, 18 and 27 are both divisible by 9
18/9=2
27/9=3
So we can make a total of 9 emergency kits, with each kit having 3 blankets and 2 flashlights
Hope this helps!!^^
