Answer:
B. or -16
Step-by-step explanation:
First, find what |-3-(-1)| is equal to.
|-3-(-1)|
= |-3+1|
= |-2|
= 2
|-3-(-1)|=2
Now we find x (I find it easier to substitute the question mark with a variable)
x÷-8=2
Lets go through our values, or answer choices:
-32/-8 = 4
This cannot be the answer
-16/-8=2
This is the correct answer.
So...
-16÷-8=|-3-(-1)|
They are equal because both sides equal 2.
Hope this was helpful and made it a bit easier to understand.

Eight children grew pumpkins and entered them in the local farmers market pumpkin contest.
The judges weighed each one (in pounds). The following is the weights of the pumpkins:
Carmen = 23.2 pounds
Noah = 23.3 pounds
Sophia = 24.9 pounds
Cole = 20 pounds
Darren = 24.4 pounds
Mohammad = 23.8 pounds
Finn - 22.5 pounds
Leah = 25.2 pounds
Please explain which of the following is incorrect:
Mean= 23.4125 pounds
Median= 23.355 pounds
Mode= 0 pounds
Range= 5.2 pounds
Answers
Answer:
mode is wrong
Step-by-step explanation:
i think the mode is wrong as it not 0 none of the numbers are repeated so you would say the mode is 23.2, 23.3, 24.9, 20, 24.4, 23.8, 22.5, 25.2 as they all appear the same amount of times which is oncw
Teacher should have written mode as “none”, because there isn’t one. No number appears more often than the others. The Mean is correct (add up all the weights, divide by 8), the range is correct (subtract lowest weight from highest), but the Median is the average of the two middle numbers, 23.3 and 23.8, which is 23.55, not 23.355.
Find the surface area of a top open cylinder
12 in radius
2 in height
Answers
The surface area of the top open cylinder is 6810.149 sq.cm.
A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.
Surface area of a cylinder = Base area + Lateral area
Base area of a cylinder = 2 × π × r²
Lateral area of a cylinder = (2 × π × r) × h
Therefore, here base area of a cylinder = 2× π × 12²
= 5837.27 sq.cm.
And, lateral area of a cylinder = (2 × π × 12) × 2
= 972.8784 sq.cm.
Therefore, total surface area of a cylinder = 5837.27 + 972.8784
= 6810.149 sq.cm.

Part I: Making the Race
Henri is Emile's younger brother and they are having a walking race. Emile can walk 2.5 meters per second whereas Henri walks 1 meter per second. Because Emile is faster, they give Henri a 45 meter head start. Emile knows Henri would enjoy winning the race, but they do not want to make the race so short that it is obvious Emile let Henri win.
1. How long should the race be so that Henri will win in a close race?
2. Describe or show your strategy on how you came up with your answer for #1.
Answers
Answer:
Step-by-step explanation:
To make the race close, the length of the race should be 450 meters.
Here's the reasoning behind the answer:
Let's first calculate how long it would take for Emile to catch up to Henri, assuming Henri starts 45 meters ahead.
The time it takes Emile to cover the same 45-meter distance is 45/2.5 = 18 seconds.
During this time, Henri would have walked a distance of 1 x 18 = 18 meters.
So, after 18 seconds, Emile will have caught up to Henri and will be 27 meters ahead of him (45 - 18 = 27).
To make the race close, we want Henri to finish just a split second before Emile. So, we can assume that Henri will finish the race just as Emile catches up to him.
Let's call the total distance of the race "d."
So, Henri will walk d meters, while Emile will walk d + 27 meters (the 27 meters is the distance Emile has to walk after catching up to Henri).
We can set up an equation to solve for d:
d/1 = (d + 27)/2.5
Solving for d, we get:
d = 450
So, the race should be 450 meters long for Henri to win in a close race.

∑ Hey, js1012201 ⊃
Answer:
(A) 4 = 10 - n
(B) 3 = n/2
(D) 8n = 48
Step-by-step explanation:
Given:
Select all the equations where n = 6 is a solution.
Choose 3 answers:
(A) 4 = 10 - n
(B) 3 = n/2
(C) 12 = n + 7
(D) 8n = 48
(E) 5 + n = 8
Solution:
Let's solve each answer choices to see where n = 6 is a solution:
-------------------------------------------------------------------------------------------------------------
(A) 4 = 10 - n
4 + n = 10 - n + n
4 + n = 10
4 + n -4 = 10 - 4
n = 6
(A) n = 6
-------------------------------------------------------------------------------------------------------------
(B) 3 = n/2
Multiply both sides by 2
2n/2 = 3 × 2
n = 6
(B) n = 6
-------------------------------------------------------------------------------------------------------------
(C) 12 = n + 7
Subtract both sides by 7
n + 7 -7 = 12 - 7
n = 5
(C) n = 5
-------------------------------------------------------------------------------------------------------------
(D) 8n = 48
Divide both sides by 8
8n/8 = 48/8
n = 6
(D) n = 6
-------------------------------------------------------------------------------------------------------------
(E) 5 + n = 8
Subtract 5 from both sides
5 - 5 + n = 8 - 5
n = 3
(E) n = 3

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answers
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.

A makeup artist purchased some lipsticks and wants to wrap them individually with gift wrap. Each lipstick has a radius of 0.4 inch and a height of 2.2 inches. How many total square inches of gift wrap will the makeup artist need to wrap 3 lipsticks? Leave the answer in terms of π.
2.08π square inches
6.24π square inches
8.32π square inches
19.59π square inches
Answers
Answer:
\(6.24\pi \: {in}^{2} \)
Step-by-step explanation:
Given:
r (radius) = 0,4 in
h (height) = 2,2 in
n (the number of lipsticks) = 3
Find: A (total surface area) - ?
First, we have to find how much gift wrap will the makeup artist need to wrap one lipstick:
\(a(surface1) = 2\pi {r}^{2} + 2\pi \times r \times h\)
\(a(surface1) = 2\pi \times ({0.4})^{2} + 2\pi \times 0.4 \times 2.2 = \frac{52\pi}{25} \)
Now, let's multiply this number by the quantity of lipsticks the makeup artist has to wrap:
\(a(total) = \frac{52\pi}{25} \times 3 = \frac{156\pi}{25} = 6.24\pi \: {in}^{2} \)
6.24t in?
Step-by-step explanation:
Given:
r (radius) = 0,4 in
h (height) = 2,2 in
n (the number of lipsticks) = 3
Find: A (total surface area) - ?
First, we have to find how much gift wrap will the makeup artist need to wrap one lipstick:
a(surfacel) = 27/2 + 27 xrx h
a(surface1) = 27 × (0.4)? + 27 x 0.4 x 2.2 = 525
Now, let's multiply this number by the quantity of lipsticks the makeup artist has to wrap:
a(total) = 55 × 3=46 = 6.24rin? R is pi

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.
