Suppose you are solving a real-world problem that contains fractions, mixed numbers, percents, and decimals. Why might it be helpful to convert all the values to one form? How would you determine which form to use?
Answers
It might be helpful to convert all the values to one form because:
1. You can't easily add or subtract values that are in a different form.
2. It is easier to visualize when working with greater than/less than problems.
______________________
I would determine which form to use based on the problem. For example, when dealing with dividing up slices of pie, it would be easiest for me to use fractions or mixed numbers, while in a problem involving how many blue buttons are in a bag of multicolored buttons it would be easiest for me to use percentages.

the larger of two numbers is five more than three times the smaller number. their sum is 33 . find larger numbers.
write the equation and find the larger number
Answers
Answer: It will be in the explanation
Step-by-step explanation:
"five more than three times the smaller number" will mean:
x = 3y + 5 [equation 1]
x + y = 33 [equation 2]
Rearrange the first equation like this :
x - 3y = 5
x + y = 33
Doing this puts the variables on the same side. Now we gotta find the value of x. In order to do so, we have to use both of the equations provided to solve and make it one equation with x and not y.
y = 33 - x
x = 5 + 3(33 - x)
Use the distributive property for 3(33 - x), which will be:
x = 5 + 99 - 3x
Further solving it:
4x = 104 [divide this by 4 to get x by itself]
Final answer is
x = 26

Key: 2 | 1 | 0 means 12 for Mountain View and 10 for Seaside
Part A: Calculate the measures of center. Show all work. (2 points)
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.

8.9+9.5r=−100.445
what is r?
first will be marked brainliest!
Answers
Answer:
Step-by-step explanation:
Begin by isolating the term with the r in it. Do that by subtracting 8.9 from both sides:
9.5r = -110.445 - 8.9 and
9.5r = -119.345 Divide both sides by 9.5 to get
r = -119.345/9.5 and
r = 12.56263158 (or you could leave it as a fraction)
8.9+9.5r=-100.445, so we have to remove the 8.9 by subtracting it from both sides.
9.5r=-109.345, but now we have to get r by itself, so we have to divide both sides by 9.5
r=-11.51

4cm x 8cm = 32cm^2
Area of the triangle: {base times height divided by two}
(4cm x 11cm) : 2 = 22cm^2
Total area = 22cm^2 + 32cm^2 = 54cm^2
Answer:
54cm^2
Step-by-step explanation:
You need to calculate area of the given figure. To solve this there are two figures together, triangle and rectangle.
first find area of rectangle given length = 8 cm and breadth = 4cm
therefore area of rectangle = l * b = 8 * 4 = 32 cm^2
To find area of triangle:
The triangle itself is divided into two right angled triangle.
Now base of one right angled triangle will be 4/2 = 2cm
Area of rt. angled trangle = 1/2 * b*h = 1/2 * 2 * 11 = 11cm^2
Therefore area of whole triangle = 11*2 = 22cm^2 (since there are two rt.angled triangle)
Total area of given figure = 32 + 22 = 54 cm^2

Answer: 35/3
Step-by-step explanation: To turn mixed numbers into improper fractions, the general rule is to :
multiply the denominator (of the fraction in the mixed number) by the whole number in the mixed number, and then adding the numerator (of the fraction in the mixed number) to give the new numerator in the improper fraction. The denominator stays the same as the one in the mixed number.
So, (denominator X whole number) + numerator = numerator of improper fraction.
In

the denominator=3
the whole number=11

5-2(x+1)=13 what is x
Answers
Answer:
x=-5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5−2(x+1)=13
5+(−2)(x)+(−2)(1)=13 (Distribute)
5+−2x+−2=13
(−2x)+(5+−2)=13 (Combine Like Terms)
−2x+3=13
−2x+3=13
Step 2: Subtract 3 from both sides.
−2x+3−3=13−3
−2x=10
Step 3: Divide both sides by -2.
−2x −2 = 10
−2 x=−5
Answer:
x=-5
