Answer:
EF = 1.58
Step-by-step explanation:
Since DE is provided (2.2), we use that in order to find EF.
First, divide the length of AB by the length of DE.
11 ÷ 2.2 = 5
So we use 5 to figure out the measurement for EF.
BC = EF, so we divide BC by 5 to get EF.
7.9 ÷ 5 = 1.58
therefore EF = 1.58
Answer:
EF is equal to 1.58
Take 11 and divide it by 2.2 to get 5, then divide 7.9(BC) and 5 which is 1.58(EF)

Answer:
2nd one
Step-by-step explanation:
Mrs. Tinney’s class has the following scores on their most recent test:
100 98 95 88 72 66 60 78 80
80
1. Calculate the five-number summary and use it to draw (and label) your box and whisker plot on a number line. Show your work for all calculations.
2. If Mrs. Aguiar’s class has a five-number summary of 50, 60, 70, 80, and 95, which class’ scores are more consistent? How do you know?
3. The mean for Mrs. Tinney’s class is 85 and the mean for Mrs. Aguiar’s class is 70. What conjecture could we make about symmetry? Explain.
Answer:
1. Five-number summary for Mrs. Tinney's class scores:Minimum (Min): 60
First Quartile (Q1): 72
Median (Q2 or Median): 80
Third Quartile (Q3): 88
Maximum (Max): 100To draw the box and whisker plot, we can plot these
values on a number line:
| | | | |
60 72 80 88 95 100
We can then draw a box from Q1 to Q3, with a line inside representing the median (Q2), and draw whiskers from the box to Min and Max.
2. Mrs. Aguiar's class scores are more consistent compared to Mrs. Tinney's class scores. This can be determined from the interquartile range (IQR), which is the difference between the third quartile (Q3) and the first quartile (Q1) in a box and whisker plot. A smaller IQR indicates less variability in the data and hence more consistency. In this case, Mrs. Aguiar's class has an IQR of 80 - 60 = 20, while Mrs. Tinney's class has an IQR of 88 - 72 = 16. Therefore, Mrs. Aguiar's class scores are more consistent.
3. Based on the mean values, we can make a conjecture about symmetry. The mean is a measure of central tendency that represents the average of a set of data points. If the mean is close to the median, it suggests that the data is approximately symmetric. In this case, the mean for Mrs. Tinney's class is 85, which is closer to the median (Q2) of 80, indicating approximate symmetry. On the other hand, the mean for Mrs. Aguiar's class is 70, which is not close to the median of 80, suggesting that the data may not be symmetric. However, further analysis using other measures of skewness or visualization techniques may be needed for a more conclusive assessment of symmetry.

Step-by-step explanation:
Mrs Dawson buys 3 yards of lace. Since there are 36 inches in a yard, she has 3 * 36 = 108 inches of lace.
She uses 30 inches of lace for the sleeves and 30 inches of lace around the waist, for a total of 30 + 30 = 60 inches of lace used.
Subtracting the amount of lace used from the total amount of lace gives 108 - 60 = 48 inches of lace left.
Since there are 12 inches in a foot, Mrs Dawson has 48 / 12 = **4** feet of lace left.

please help!!!! where do i put the number line/s
Answer:
Put the arrow on -1.3.
Step-by-step explanation:
In order to find -1.3, we first have to solve the problem.
-2 - (-0.7)
Since negative - negative = negative, we know our answer is already going to be negative.
Subtract -0.7 from -2, and to make it easier you can do it on a calculator if you want.
First remove the brackets, then turn the negative sign on -0.7 and the minus sign into a plus sign. It will turn into:
-2 + 0.7
When you add, 0.7 to -2, the sum is -1.3.
Therefore you mark the arrow on -1.3

Triangle ABC ~ triangle DEF. Use the image to answer the question.
a triangle ABC with side AC labeled 7.32 and a second triangle DEF with side DE labeled 8.8, side FD labeled 6.1 and side EF labeled 6.4
Determine the length of side AB and BC in triangle ABC.
AB = 10.065, BC = 8.388
AB = 8.8, BC = 6.4
AB = 10.56, BC = 7.68
AB = 7.425, BC = 5.954
Answer:
AB = 10.56 BC = 7.68
Step-by-step explanation:
With AC provided, we first have to find the quotient of AC and DF.
AC = 7.32
DF = 6.1
7.32 ÷ 6.1 = 1.2
So AC's dimensions are 1.2 times larger. So we use 1.2 to find AB and BC.
The similar sideline of AB is DE, and DE = 8.8
So we multiply 8.8 by 1.2
8.8 x 1.2 = 10.56
AB = 10.56
We do the same for BC. BC's similar sideline is EF, and EF = 6.4
6.4 x 1.2 = 7.68
BC = 7.68
Therefore AB = 10.56 and BC = 7.68
Find the approximate radius of a circle with a circumference of 2 kilometers. Use 3.14 for π. Round to the nearest hundredth if necessary.
Answer:
0.32 (rounded to the nearest hundredth)
Step-by-step explanation:
If you have any questions ask me please! :)
Answer:
0.32 km
Step-by-step explanation:
Using the formula r = c / (2 * π), where c = 2 kilometers and π = 3.14, we can calculate the radius as:
r = 2 km / (2 * 3.14)
r = 2 km / 6.28
r = 0.31847133758 km
Rounding this to the nearest hundredth gives:r ≈ 0.32 km
Therefore, the approximate radius of the circle is 0.32 kilometers.
Mr. Walker brought 100 cookies for two classes at school one class had 28 students, and the other had 27 students plus their two teachers. he also left 10 for the office staff and 5 for the custodians. How many cookies did he have leftover?
Answer:
Mr. Walker gave out a total of 28 + 27 + 2 = 57 cookies to the two classes and left 10 + 5 = 15 cookies for the office staff and custodians.
Therefore, the number of cookies left over is:
100 - 57 - 15 = 28 cookies
Mr. Walker had 28 cookies left over.
Step-by-step explanation:
Answer: 28 cookies
Step-by-step explanation:
We have to add up the number of cookies distributed and subtract it from the total amount of cookies he brought in order to find out how many cookies he has left over.
----------------------------------------------------------------------------------------------------------
First classFor the first class with 28 students, Mr. Walker distributed 28 cookies.
----------------------------------------------------------------------------------------------------------
Second ClassThere are 29 people in the second class, which has 27 students and 2 teachers.
Mr. Walker then gave out 29 cookies.
----------------------------------------------------------------------------------------------------------
Office Staff and CustodiansMr. Walker left 10 for the office staff, 5 for the custodians, which is a total of 10 + 5 = 15.
So, Mr. Walker distributed 15 cookies.
----------------------------------------------------------------------------------------------------------
Finding the answerWe add up the number of cookies distributed to figure out how many cookies he had leftover:
28 + 29 + 15 = 72.
This gets subtracted from the total number of cookies brought by him:
100 - 72 = 28.
----------------------------------------------------------------------------------------------------------
AnswerTherefore, after giving cookies to the two classes, the office staff, and the custodians, Mr. Walker had 28 cookies left over.

Can someone please explain to me how this works or something please? This is a very hard subject for me T-T
Answer:
29.2 ft
Step-by-step explanation:
a^2 is the base so it’s how long the shadow is.
b^2 is the leg so it’s the height of the tree
c^2 is the hypotenuse so it’s the top of the tree to end of the shadow (what your trying to find)
25^2 + 15^2 = c^2
625+ 225= c^2
850= c^2
(square root both sides)
29.2= c

Answer:
x + .1x = 17,402
1.1x = 17,402
x = 15,820
The two numbers are 15,820 and 1,582.
15,820 - 1,582 = 14,238
Answer: 14238
Step-by-step explanation:
As one of the numbers is divisible by 10, it is of the form 10*x. When the units digit is erased x is left. From the information provided in the question, x + 10x = 17402
=> 11x = 17402
=> x = 17402/11
=> x = 1582
The two numbers are 1582 and 15820. The sum of these numbers is 17402. The difference of the two number is 14238.
The required difference of the numbers is 14238.
Please help asap! Finding the Volume of a Cylinder... Tysm!♡♡
Answer:
i belive its 22Step-by-step explanation:
V = 22To find the volume of 11 x 2, you need to know the third dimension, as volume is a three-dimensional measure. Assuming you mean the dimensions of a rectangular solid, you would need to know the height or depth of the object to calculate the volume. As for screen time for children, the American Academy of Pediatrics recommends limiting it to one hour per day for children aged 2-5 and to no more than two hours per day for children aged 6 and older. Engaging in creative play can help children develop important skills, such as problem-solving and communication, while excessive screen time has been linked to negative effects on cognitive and social development.
and 11 x 2 = 22.Answer:
The answer is 22
Step-by-step explanation:
You have to multiply the base times the height (2 x 11) Doing that will get you 22 ft.

Answer:
G. x = 6/5
Step-by-step explanation:
There are 5x's and 4 ones on the left side ==> 5x + 4
There are 10 ones on the right side ==> 10
Equation left and right side expressions gives the equation:
5x + 4 = 10
Subtract 4 on both sides:
5x + 4 - 4 = 10 -4
5x = 6
Divide by 5 both sides
5x/5 = 6/5

A′(0, 0), B′(−5, −2), C′(5, −5), D′(3, 0)
A′(0, 0), B′(−5, −2), C′(−5, 5), D′(0, 3)
Answer: A′(0, 0), B′(−2, 5), C′(5, 5), D′(3, 0)
Step-by-step explanation:
Because since it is 90 degrees counterclockwise you would do the 270 formula since it is counterclockwise and the formula for 270 degrees is basically swapped the x and the y and add a negative to the original y and if it's already a negative it becomes a pthe polygon, so the answer is A (0, 0), B(-2, 5), C(5, 5), D(3, 0) the first one credits too : Kfn032409
