If possible, please explain in words, thank you. :)
Find the area of the circle when C = 4π. Give your answer in terms of π.
Answer:
12.56
Step-by-step explanation:
So, the circumference will be 4(3.14), which is 12.56. So, now you can solve for area. By the way, the formula is: C = pi(d) (Just saying)
Anyways, A = pi(r)2. So, with the radius being half of the diameter, you will cut 4 in half. You are now ready to solve.
A = 3.14 (2) (2), which is 12.56 .
Hope this helps! :)
Lily and Mackenzie collected some stamps. If Lily gave 4 stamps to Mackenzie, Mackenzie would have twice as many stamps as Lily. If Mackenzie gave 4 stamps to Lily, they would have the same number of stamps. How many stamps did each girl have?
GIVING BRAINLIEST. PLS HELP. SHOW UR WORK TOO
Answer: hope this helps ♡
Lily had 16 stamps and Mackenzie had 20 stamps.
Step-by-step explanation:
Lily gives 4 stamps to Mackenzie
(Mackenzie) m + 4 = 2(L - 4) (Lily)
Solve for Lily:
m + 4 = 2L - 8
m + 4 + 8 = 2L
(m + 12) ÷ 2 = 2L ÷ 2
(m + 12) ÷ 2 = L
L = (m + 12) ÷ 2 (we will substitute this value for L in the second equation)
Mackenzie gives 4 stamps to Lily
(Mackenzie) m - 4 = L + 4 (Lily)
m - 4 = ((m + 12) ÷ 2) + 4
m × 2 - 4 = ((m + 12) ÷ 2 × 2) + 4
2m - 4 + 4 = (m + 12) + 4 + 4
2m - m = (m - m + 12) + 8
m = 12 + 8
m = 20 (we will substitute this value of m in the next equation)
L = (m + 12) ÷ 2
L = (20 + 12) ÷ 2
L = 32 ÷ 2
L = 16
solve for value of y FOR BRAINLIEST PLEASE :)

Marty went shopping for school supplies. He bought a package of pens for $2.25, a package of paper for $3.25, a notebook for $5.75, and a package of folders for $3.75. What was the range of prices for the school supplies that Marty bought?
Answer:
$3.50
Step-by-step explanation:
to find the range you take the highest number and the lowest number and subtract them
so with that, let us do just that-
$5.75, $3.75, $3.25, $2.25
$5.75-$2.25
=$3.5
and since we're dealing with money we must add a '0' to the end of the decimal- $3.50
good luck :)
i hope this helps

given that there is one possible outlier. if the outlier was removed from the data set, how would it effect the measures of central tendency? {8, 73, 74, 75, 79, 85, 85, 92, 94}
(not links)
O Mean increases median decreases
O Mean decreases median increases
O Both mean and median increase
O Both mean and median decrease
Answer:
Some measures I believe you are talking about are mean, median, mode, and range.
Mean is the average of all values. This is found by adding up all numbers and dividing by the amount of numbers. Outliers greatly affect and "throw off" the mean, making it inaccurate at calculating the average without an outlier.
Example:
1, 2, 4, 6, 10
(1 + 2 + 4 + 6 + 10)/5 = mean = 4.6
1, 2, 4, 6
(1 + 2 + 4 + 6)/4 = mean = 3.25
Because of this, mean does change when adding and removing outliers, and is therefor not the answer.
Median is the middle of the data. This is found by ordering the values in the data set from least to greatest (or greatest to least, either one works) and finding the number in the center of all the values. If there were an outlier, the median wouldn't be skewed as the mean is by outliers, but it would change.
Example:
1, 2, 4, 6, 10 Median = 4
1, 2, 4, 6 Median = 3
So median is not the answer, because it is affected by adding and removing outliers.
Mode is the value in a data set that appears the most. Outliers are numbers that are significantly lower or higher than most or all of the other numbers in a data set. Because of this, there can't be more outliers than other numbers, so it is impossible for the mode to be an outlier.
Example:
1, 1, 1, 2, 3, 4, 4, 86 Mode = 1
1, 1, 1, 2, 3, 4, 4 Mode = 1
This means the mode is not affected by adding and removing outliers.
Mode is a possible answer, but let's take a look at range before coming to a conclusion.
Range is the spread of values in a data set. In other words, the difference between the highest and lowest value. A high range can signal a possible outlier is present.
Example:
1, 2, 4, 6, 10
10 - 1 = highest value - lowest value = range = 9
1, 2, 4, 6
6 - 1 = highest value - lowest value = range = 5
The range is certainly affected by outliers, so it is not the answer.
Out of mean, median, mode, and range, the answer to this question is mode.
If an outlier is removed, mode will not change.
Hope this helps!

The dot plot shows a random sample of number of miles completed in a session by two different running clubs. Compare the mean values of the dot plots. Round to the nearest tenth. Which makes a comparative inference about the runners in both clubs?
(A) There is about the same variation in the number of miles run by each member in both clubs.
(B) There is less variation in the number of miles run by the members of Club Fit than by the members of Club Agile.
(C) There is less variation in the number of miles run by the members of Club Agile than by the members of Club Fit.
Please help me with the work
Answer:
1. you answered correctly :)
2. how many 1/4's go into 12? in other words multiply 12 and 4 to get 48/4
3. Draw a diagram of 1/5ths until it equals 15 (you'll need a total of 75 boxes)
4. the problem is 18z=72 so you need to divide 72 and 18. 72/18=4. therefore z equals 4.
5. make up a division problem that has the answer of 8. for example 24/y=3. y will equal 8. and then use a tape diagram for that.
6. make up a multiplication problem that has an answer of 8. for example 3y=24. y will equal 8. and then use a tape diagram for that.
7. Meghan is correct. when you have y divided by two you need to do the opposite and multiply both sides by two. Meredith was incorrect because she switched the division and multiplication signs completely which is not what you are supposed to do.
Step-by-step explanation:
I hope this helped :) (the only thing you could write down word for word is #7. for 1-6 just read what i have to say and follow the directions and it should help) have a great day!!!!
I will solve these equations algebraically.
Here you are:
1. 30= 5w
Divide each side by 5.
30÷5= 5w÷5
6 = w
∴ w= 6
To check,
30=5w
Substitute w for 6
30= 5 x (6)
30= 30
LS= RS
(You were correct, great job!)
2.
12 = x÷4
Multiply each side by 4.
12 x 4 = x/4 x 4 ↔ 4 and 4 cancel out.
48= x
∴ x=48
Checking:
12= 48÷4
12= 12
LS=RS
3.
y÷5=15
Multiply each side by 5.
y÷5 x 5= 15 x5
y =75
∴y=75
Checking:
Substitute y for 75.
y÷5=15
75÷5=15
15=15
LS=RS
4.
18x=72
Divide each side by 18.
18x ÷ 18= 72÷18
x = 4
∴x= 4
Checking
18x=72
18(4)=72
72=72
LS=RS
I hope that these solutions helped you. I am sure that using the solutions, you can figure out the other questions on your own.

Which one of the numbers does not belong in the following series?
2 - 5 - 7 - 14 - 41 - 122 - 365 - 1094 - 3281
A-FIVE
B-SEVEN
C-FOURTEEN
D-FORTY-ONE
E-ONE HUNDRED TWENTY-TWO
Answer:
i think 7
Step-by-step explanation:
Option B: SEVEN
The number that goes not belong in the following series is SEVEN
Given :
The numbers in the series is
2 - 5 - 7 - 14 - 41 - 122 - 365 - 1094 - 3281
First number is 2
[tex]2 \cdot 3 -1=5\\[/tex]
Lets multiply the previous term by 3 and subtract 1 to check the other terms
[tex]5 \cdot 3 -1= 14\\14 \cdot 3 -1= 41\\41 \cdot 3 -1= 122\\122 \cdot 3 -1= 365\\365 \cdot 3 -1= 1094\\1094 \cdot 3 -1= 3281\\[/tex]
From the series we can see that 7 does not belong to the series .
So, SEVEN does not belong to the series .
