rewrite in simplest terms: −10(−2p+10)−4p
Answers
Answer:
16p-100
Step-by-step explanation:
All we have to do is evaluate this expression.
The first step is to distribute -10 among the numbers in the parenthesis:
20p-100
We got 20p-100 from first multiplying -10 to -2p, which the negatives would cancel out and get 20p, and -10 multiplied by 10, which gets you -100
The next step is to subtract the 4p from the entire expression:
20p-100-4p
Or, we can rearrange this expression to make it clearer: 20p-4p-100
=16p-100

The length of a rectangle is represented by 9x - 5. The width of the rectangle is represented by 3.
Write two equivalent expressions that represent the Area of given rectangle.
Answers
Answer:
First factor the Area
Area = 18x2+12x+2
Factor out a 2
Area = 2(9x2+6x+1)
Factor this and you get
Area=2(3x+1)(3x+1)
Let L be Length and W be Width
Area=LW
and the Length is twice the Width so
L=2W
Area=2(3x+1)(3x+1) so
L=2(3x+1)
W=3x+1
This can also be written as if you distribute the 2
L=6x+2
W=3x+1

We would add the total responses recorded in the Girls row, which is equal to 32. We would then subtract it from the total of that row, 38. 38 - 32 is equal to 6. 6 girls chose their answer as English. We can check our work by adding the responses to see if they added up to the total. Now we move to the boys. The Maths column is 5. The boys row is missing 2 things - english and total. We can find the total by subtracting 38 from 70. This is equal to 32. Now, we can add 7 and 5 (12) and subtract from the row total (32). This is equal to 20. 20 boys chose English.
Now we add the girls and boys. 6 + 20 is equal to 26. 26 is your answer.

What is the distance traveled by the tip of the second hand of a clock in 1 minute if the hand is 10.5 inches long? Leave your answer in terms of π.
Answers
Answer:
(1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.
Step-by-step explanation:
The distance travelled by the tip of the second hand of a clock in 1 minute, if the hand is 6 cm long, is approximately 3.6 degrees or approximately 0.06283185 radians. This is because the circumference of a complete circle is equal to 2π radians, and a clock face is divided into 60 equal parts, so each part is equal to 1/60 of 2π or 1/30π radians. To convert this to cm, you can multiply by the length of the second hand, which is 6 cm. Therefore, the distance travelled is (1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.

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.

What is The Diary of Anne Frank?: It's the first, and sometimes only, exposure many people have to the history of the Holocaust.
1. How is this scene the happiest they have been since going into hiding?
In my opinion, this scene is the happiest they have been since going into hiding because the holocaust was very brutal because many individuals got executed and frightened throughout the Holocaust, and opening the gifts was a good way to temporarily forget about their problems.
2. Why does Margot not want to blow out the candles? Why does Mr. Frank say they need to?
Margot does not want to blow out the candles because they are supposed to be left to burn themselves out. Mr. Frank tells her God will understand that they need to conserve their Candles.
3. Explain Peter's prank on Mr. Dussel.
Peter was coming from his room as he was holding something in his coat which turned out to be a towel, but Mr. Dussel thought it was a cat. In the end, he was allergic to his clothes.
4. How does everyone react to Mr. Dussel's cat allergy?
Some seem to laugh at Mr. Dussel's cat allergy, but Mr. Van Dans wants to throw out Peter's cat for always eating their food. Peter said if Mr. Van Daans throws out the cat he will go out with it, but it didn't happen.
5. What happens that makes the mood change?
Something crashes below and they all freeze in horror. Peter tries to reach the lamp, but he can't so he gets up on a chair to try again but he ends up losing his balance and falling and then more steps can be heard below.
6. How was this scene the most scared
they have been since going into hiding?
Because they thought it was the Green Police or the Gestapo that have discovered their hiding place and had come to get them.
7. Describe juxtaposition and explain how this scene is an example of juxtaposition.
A writer can make readers sense of "goodness" in a particular character by placing him or her side-by-side with a character that is
predominantly "evil." In my opinion, this scene is an example of juxtaposition when Peter and Mr.
Van Dans had an argument about the cat, making Peter seem like a positive character while making Mr. Van Dans look like a negative character.
8. Describe how each person reacts in the situation when they are scared.
Mrs. Van Dans was panicking and saying to give the Green Police money
Anne was more concerned for her father because he went to check what happened below while her mother was trying to calmly put her in a state of relief. At some point, Anne asked who is going to look for Mr. Frank and Peter offered to show that he wasn't scared of any danger but Mr.
Dussel pushed Peter away in an angry tone. Mr.
Van Dans was as well calm and seemed to be more focused on what could happen next.
(I hope I did get every one right )
9. List the gifts that Anne gave to each person for Hanukkah. Then show how these gifts represent Anne maturing by saying what the thought or meaning behind each gift is.
1. Margot Frank: A crossword puzzle book / She never loses her temper.
2. Mrs. Van Dans: Hair shampoo / Mrs. Van Dans likes her hair (it doesn't seem to say in this scene, so I don't exactly know)
3. Mr. Van Dans: 2 cigarettes / Mr. Van Dans enjoys smoking (same as above)
4. Mrs. Frank: Ten hours of Anne doing what she says / Anne didn't get the time to repay her (that's what it made me believe)
5. Mr. Frank: A scarf / He found it in the first
scene
6. Mushi: A ball of paper with a string attached to it / For the cat to play with and stay entertained.
7. Peter: a safety razor / Peter was growing a mustache.
8. Mr. Dussel: earplugs / So he won't hear Anne making noise at night
Anne is maturing way faster because of the problems of what happens outside of their hiding as well. Every meaning of the gifts shows that Anne can see every little detail about people which not many kids can do.
l am sorry if l'm late, I had to do some research and listen to the audiobook of the specific scene.

Margo is wrapping a box that is 7 inches long, 10 inches wide, and 4 inches high. How much wrapping paper will she need to cover the entire box?
Answers
She will need to cover six sides of the box. To calculate the surface area of the box, you'll need to add the area of each side. The formula for surface area is: 2lw + 2lh + 2wh. Plugging in the dimensions of the box, we get:
2(7 x 10) + 2(7 x 4) + 2(10 x 4) = 140 + 56 + 80 = 276
So, she will need 276 square inches of wrapping paper. But since she doesn't need to wrap the bottom of the box, we subtract one of the sides, which gives us a total of 268 square inches of wrapping paper.
To calculate the surface area of the box, you need to add the area of all six sides. The area of each side can be found by multiplying the length by the width.
- The area of the front and back sides is 7 x 4 = 28 square inches each.
- The area of the top and bottom sides is 10 x 4 = 40 square inches each.
- The area of the two side sides is 7 x 10 = 70 square inches each.
So, the total surface area of the box is 2(28) + 2(40) + 2(70) = 56 + 80 + 140 = 276 square inches.
Therefore, Margo will need at least 276 square inches of wrapping paper to cover the entire box.
Answer:280 in
Step-by-step explanation: First we multiply the length by the width and that would be 7 by 10 and we would get 70. Next we multiply the height by the total of (l x w), so 4 x 70 would be 280. Margo needs a total of 280 inches of wrapping paper to cover the entire box. Hope this helps! :)

Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128
128/8=16

I haven't done these in 2 years and I'm not sure if I remember things correctly but here's what I would put down.
5) No, it is not because the sizes of each section are not even.
6) Yes, this is fair since there are a even chance of getting each number.
7) 3 out of 25 or 3/25
8) The bag with 250 colored tiles would give him a less chance of picking a blue tile. In the first bag, there is a 40% chance that Greg would pick a blue tile while the second bag, he would have a 30% chance of picking a blue tile. To get these percentages, I divided the the amount of blue tiles in the bag by the total amount of tiles.
Explantion for question 8: 10 blue tiles in a bag of 25 so you would do 10/25 which is .4 and as a percentage it would be 40%. For the second question, 75 blue tiles out of 250 total so 75/250 and that would be .3 and as a percentage, it would be 30%. The "/" is a fraction bar and is sometimes used as a division symbol as well, just in case you don't know:)

Answers
During the first week of her training, she runs 200 meters. On the second week, she plans to run 50% more.
Now, how do you calculate this?
To increase 200 meters by 50%, multiply by 1.5
The second week she pans to run 450 meters.
Since there are only 3 weeks, do it again!
The thrid week, she plans to run 675 meters.
Since she runs the same ammount each day of the week, the calculation is simple.
7(200) + 7(450) + 7(675)
In these three weeks, she runs 9275 meters.
OR, she runs 10143.26 yards.
