Step-by-step explanation:
1) Find [tex]\frac{1}{6}[/tex] of 48
To find this we have to do 48 divided by then multiplied by one!
48 ÷ 6 = 88 × 1 = 8This means that the teacher graded 8 quizzes before school.
2) Add how many was graded after school
We know that the teacher also did 15 of how many quizzes were left over after school.
Previously he/she had done 8 so we have to subtract this by 48
48 - 8 = 4015 more were done so we have to subtract this too...
40 - 15 = 2525 are left!
Hope this helps, have a lovely day! :)
Answer:
25 quizzes
Step-by-step explanation:
48/6=8
8+15=23
48-23=25

Meg laid 15 tiles in 50 minutes.
Jessica worked for 85 minutes at a faster rate per tile than Meg.
Choose all the rates that could be Jessica’s rate.
20 tiles in 85 minutes
24 tiles in 85 minutes
28 tiles in 85 minutes
1 tile in 3 minutes
1 tile in 4 minutes
Answers
Answer:
The correct options are C and D
Important information:
Meg laid 15 tiles in 50 minutes.
Jessica worked for 85 minutes at a faster rate per tile than Meg.
Step-by-step explanation:
The rate per tile of Meg is:
Rate = time/no. of tiles
Rate = 50/15
Rate = 3.333333...etc
Calculate the rates per tile for each option.
85/20 = 4.25
85/24 = 3.54167...
85/28 = 3.0357
3/1 = 3
4/1 = 4
From the above calculation is clear that the time spent per tile is less than Meg's rate in options C and D.
Therefore, the correct options are C and D.

-Graphing Linear equalities with slope and y-intercept-
Answers
Answer:
If Ali has $9 and spends $2 each week buying chips. This means that the equation is: y = 9 - 2x. This is because the equation is calling for the amount of money Ali has left, which means that you have to subtract 2 times the amount of weeks passed from 9.
Week 1 ---- y = $7
Week 2 ---- y = $5
Week 3 ---- y = $3
You can also notice that each week the amount of money Ali has left decreases by 2.

QUESTION 1
The value of the x for the given square such that its perimeter is 28 meters will be 3.7 meters.
What is a square?
A square is a geometrical figure in which we have four sides each side must be equal and the angle between two adjacent sides must be 90 degrees.
Area of square = Side²
The perimeter of the square = 4 × side
As per the given square perimeter.
4(x + 3.3) = 28
x + 3.3 = 7
x = 3.7 meters.
Hence"The value of the x for the given square such that its perimeter is 28 meters will be 3.7 meters".

The charity gala costs a flat fee of $4, plus an additional $11 per attendee. Is the total cost directly proportional to the number of attendees?
Answers
No, the total cost is not directly proportional to the number of attendees because there is a flat fee of $4 that does not depend on the number of attendees. If the total cost were directly proportional to the number of attendees, then the cost per attendee would be constant regardless of the number of attendees, but in this case, the cost per attendee decreases as the number of attendees increases due to the fixed flat fee.
Factor this expression completely and then place the factors in the proper location on the grid.

Write the equation for the line of best fit in the slope-intercept form and use it to predict the number of matches that could be won after 13 months of practice Show your work and include the points used to calculate the slope. (5 points)
Answers
The slope-intercept is y=mx+b where m= the slope and b= the y-intercept. it looks like the y-intercept is about 3.5 or 3 1/2. One way to find M is that you take 2 points, ill do (1,5) and (5,12), and then subtract the x's with the x's and the y's with the y's and you would get (1-5, 5-12) which equals -4,-7. then you put the y's on top of a fraction and the x's on the bottom. so you would get -7/-4 when both numerator and denominator are both negative then they cancel out. making the total M= 7/4 which also equals 1 and 3/4, since you want to know after 13 months, the number of months =x so you can substitute and this is your equation: y= 7/4x+ 3.5 substituting the number of months: y= 7/4(13) + 3.5. 7/4 * 13 = 22.75 then you add the 3.5 which equals 26.25 so.
after 13 months of practice, the number of matches won would be about 26.
HELPPP!!!!! Spencer has 16 blue marbles and 8 white ones. If he wants to place them in identical groups without any marbles left over, what is the greatest number of groups Spencer can make?
please give an explanation so i can stop asking for help
Answers
Answer: 8
Step-by-step explanation:
One way to find the GCF (Greatest Common Factor) is to list the factors of each number and find the largest factor that they have in common.The factors of 16 are: 1, 2, 4, 8, 16
The factors of 8 are: 1, 2, 4, 8
The largest factor that 16 and 8 have in common is 8.
This means that the marbles can be divided into 8 identical groups, each containing 2 blue marbles and 1 white marble.
Therefore, the greatest number of groups Spencer can make is 8.

Two friends have gone on vacation together. On Monday, they each chose a different activity. One friend went in a helicopter and went 128 feet above the ocean. The other friend decided to go diving and he was 28 feet below sea level in the water. What is the distance between the 2 friends if they were directly above each other at the same time?
Answers
Answer: The answer would be 100.
Step-by-step explanation: The answer would be 100 because one friend is 128 feet above the ocean right, then the other friend is 28 feet below sea level in the water OK. So if one is 128 feet above sea level then that's a positive 128 feet. Now if the other friend is 28 feet below sea level in the water well then that's a negative 28 feet. So then what I would do is i would subtract 128 from 28 and get my answer of 100 feet apart from each other. Hope i helped and have an amazing day, and good luck on any upcoming test that you might have. I hope you Ace them all:) Good day buddy.
A spinner with five equal-sized colored sections is spun with the results shown in the table. Based on the experimental probability, predict the number of yellow results for 300 trials.
Red Orange Yellow Green Blue
16 15 20 14 15
A.75
B.60
C.40
D.20
Answers
Answer: 75
Step-by-step explanation:
Add the values given in the table
16+15+20+14+15 = 80
Yellow happens 20 times out of the 80 times total.
The experimental probability of yellow is 20/80 = 1/4 = 0.25 = 25%
If we do 300 trials, then we predict yellow to happen 0.25*300 = 75 times.
