x = Raul's marshmallows
#1
y = Jenny's marshmallows
x + 6 = y
Raul and Jenny each drank a
cup of hot chocolate after
playing in the snow. Jenny put 6
more marshmallows in her cup
than Raul. Together, they had a
total of 30 marshmallows. How
many marshmallows did each
person have?
x + y = 30
Answers
Raul has 12 marshmallows
All I did was divide thirty by 2 (because there were two people) and got 15. After I added 3 to Jenny’s side and subtracted that from Raul’s side.

Owen earned some money at a summer job. He saved 1/4 of the money and spent 1/3 of the rest on a t-shirt. He then spent the remaining money on downloading some songs. 1.What fraction of the money did he spend on the downloads?
2. If the t-shirt cost 20$, how much money did Owen earn at the summer job?
Answers
He saved 1/4 of the money
3/4 (remaining money lets call it RM)
*answers question 1 * Since he spent 1/3 of the RM on shirt we need to subtract 3/4 (our RM) by 1/3
3/4 - 1/3 = 5/12
the remaining money he spent of downloads is 5/12 of the total money he earned.
He spent 1/3 of the R on a $20 dollar T-shirt, and if $20 is 1/3 of the remaining money then that means that he had 60 dollars he has not saved. (20 x 3 = 60)
*answers question 2* if $60 is 3/4 of the total money he earned then he earned a total of $80 dollars from his summer job.
60/3 = 20
60 + 20 = 80

Describe features that determine a translation, rotation, and reflection.
Answers
Translation: It’s a transformation that moves every point in a figure the same distance in the same direction.
Rotation: It’s a a transformation that turns a figure about a fixed point.
Reflection: It’s a transformation that takes a shape/preimage and flips it across a line called the line of reflection to create a new shape/image.
Answer:
np!..Brainliest pls
Step-by-step explanation:
translation:- its not rotated,reflected or resized.
rotation:-the roation is the same size and shape
reflection:- the preimage is flipped,across a line of reflection to create the image.Each point of the image is the same distance from the line as the preimage is, just on the opposite side of the line.
A cardboard storage carton has a length of 3 feet, a width of 2 feet, and a volume of 12 ft³.whatis the minimum amount of cardboard needed to make the box? [hint: you're given volume, so find the missing height. then use your 3 dimensions to find the total surface area.]
Answers
Brainlist pls
Volume = Length x Width x Height
Substituting the given values, we get:
12 = 3 x 2 x Height
Solving for the height, we get:
Height = 12 ÷ (3 x 2) = 2 feet
Now, we can use the dimensions to find the total surface area of the box. The surface area of a rectangular box can be found using the formula:
Surface Area = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the box, respectively.
Substituting the given values, we get:
Surface Area = 2(3 x 2) + 2(3 x 2) + 2(2 x 2) = 12 + 12 + 8 = 32 square feet
Therefore, the minimum amount of cardboard needed to make the box is 32 square feet

Answers
5 is the answer.
Review:What is a cuboid?
A cuboid is a rectangle, but in 3D form.
Do we calculate area or volume in a cuboid?
We calculate the volume for 3D shapes. For 2D shapes, area is used.
If/Then:
Now, if the volume of the cuboid is 24 units³ then:
x × x × y
Now, lets fit all our options to see which one is NOT the dimensions.
Option A:
x × x × 3 = 24 units³
x × x = 12 units³ ✔
This is possible.
Option B:
x × x × 4 = 24 units³
=> x × x = 6 units³ ✔
This is possible.
Option C:
x × x × 5 = 24 units³
=> x × x = 24/5 units³ ❌
This is not possible. This will be our answer.
Option D:
x × x × 6 = 24 units³
=> x × x = 4 units³✔
This is possible.
Conclusion:
So after working on our problem, we can conclude that C is our answer. Hoped this helped.

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Answers
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500

Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
Answers
For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

Of 630 seats in the cafeteria, 70% are in use. How many seats are being used?
Answers
Answer:
70
Step-by-step explanation:
630 divided by 70 is 9, so then you take 630 again and divide it by 9 to get 70
I know this because if you set up the equation as a fraction you will get:
x/630 and 70/100
if you multiply 630 by 70 you get 44100,
but you then take the 100 and divide 44100 by 100 and you get 441 using the cross multiply method.
