Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

Jaden made a rectangular sign that is 1.4 meters long and 1.2 meters wide to post on the wall of his store. How many square meters of wall does the sign cover? The answer is 1.68, but to solve the problem, you need to find 1.4 x 1.2(which it is 1.68). Estimate the area of wall that the sign will cover. Explain your thinking please.
Answers
First, we can round the dimensions of the sign to the nearest whole number to make the multiplication easier. Rounding 1.4 to 1 and 1.2 to 1, we can estimate that the sign covers approximately 1 square meter of wall.
This estimation assumes that the sign is placed directly on the wall with no gaps or overlaps. In reality, the actual area of wall covered by the sign may be slightly larger or smaller depending on the installation method and any spacing between the sign and the wall.
It's important to note that while estimation can be useful for getting a rough idea of the answer, it's not always accurate and should not be relied upon for precise calculations. In this case, using the actual dimensions of the sign to find the area of the wall covered (1.4 x 1.2 = 1.68 square meters) gives a more accurate result.

For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.
Answers
Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11
To find the mean, we sum up all the values in each data set and divide by the number of values:
Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes
Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.
In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.
In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.
Based on these observations, we can conclude that the most plausible data set for Diego is:
Data Set A: 9, 11, 13, 10, 12
This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.

Answers
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
Answer:
I believe the answer is D.

Here is a scale drawing of a garden. Kim wants to plant a tree in the garden according to the following rules: It must be 7 m from A and 4 m from C. Place a cross where Kim can plant the tree.
Answers
Answer:
If the scale is 1 or more cm to every meter you can count 7 from A
if it is 2cm to every meter you can count 6cm and count this as 3 meter so that when you extend another 6cm you have 3m +3m = 6 meters it would just be 2 more cm to count for 1 m to equal it has 7m.
Repeat for 4m for C which is 4 groups of cm depending what the scale is.
The two should meet at a cross the same as counting one direction from 7 and counting across for 4 in another direction.
Step-by-step explanation:
On the scale drawing of the garden, the point to plant the tree is 3.5cm from point A and 2cm from point C
The scale factor is given as: 1 cm represents 2 m
From the question, we understand that the point to plant the tree is 7m from point A and 4 m from point C
Using the scale factor, the location of the point is calculated as follows:
\(\mathbf{A = \frac{7cm}{2}}\)
\(\mathbf{A = 3.5cm}\)
\(\mathbf{C = \frac{4cm}{2}}\)
\(\mathbf{C = 2cm}\)
This means that the point is 3.5cm from point A and 2cm from point C

Find the mean of the integers: 17, -25, 3, -29, -15, 7
Answers
Answer: -7
Step-by-step explanation: To find the mean, here is the equation =
Divide the sum of all values in a data set ÷ the number of values = mean (average)
Step 1 :
So we do =
17 + -25 + 3 + -29 + -15 + 7 = -42
So the sum of the integers is -42
Step 2 :
We divide the sum by the number of values.
17, -25, 3, -29, -15, 7
1 2 3 4 5 6
So there are 6 values.
We do =
-42 ÷ 6 = -7
So the mean (average) of these integers is -7

Answers
Answer:
Step-by-step explanation:
To find the median, we need to arrange the data in ascending order:
70, 71, 72, 74
Since the data set has an even number of values, the median is the average of the two middle values. In this case, the two middle values are 71 and 72. Therefore, the median is:
(71 + 72) / 2 = 143 / 2 = 71.5
So, the median for the given set of data is 71.5.

2hrs / 75pgs = x / 350pgs (the relation )
(350pgs) (2hrs / 75pgs) = x (divide both sides by 350 to isolate x )
9-1 / 3hrs = x (solve for x )
