To find the unit rate:
Divide 5.25 feet by 3 feet, and I got 1.75, so the unit rate would be 1.75 feet(Jorge’s height)/1 foot of shadow. A shorter version of this would be 1.75/1
Then, now that you know the unit rate, or how many feet in height for every one foot of shadow, you multiply 1.75 by the length of the shadow (23 feet). For this I got 40.25.
40.25 is the height of the flag pole :)
Answer:
40.25 feet tall
Step-by-step explanation:
There is a small triangle made by the boy and the three feet of shadow. This triangle when scaled up will be the same as the flag and the full shadow.
To do this you need to find how much to multiply 3 by to get 23.
First you do 23/3 which will give you 7.6 repeating. or 7.6666666666... (same thing)
If you then multiply that number by the boy's height 5.25 you will get the answer 40.25.
This is because the triangle the flag creates is 7.666... times larger than the triangle the boy creates.
48 / 2(9 + 3) = ?
Don't mind this text: sdlkajflaskdjflasdj;lfksjd;lfkaa
Answers
Answer:
1/2
Step-by-step explanation:
distribute the 2 to the 9 and 3 then add 18 to 6 to get 24 then simplify 24/48
\(\frac{48}{2(9+3)}\) = 2
48 / 2(9 + 3) = 288
Step-by-step explanation:NOTE: I am note sure if this was originally in fraction format, but I will show you how to solve it if it was, and for if it is like the equation to the left.
FRACTION:
1. If it is in fraction: =\(\frac{48}{2(9+3)}\)
I just changed this into a fraction because I find that when using division in math problems that works best (in my experience).
2. Parenthesis: =\(\frac{48}{2(12)}\)
Start doing PEMDAS. Since you have parenthesis in the denominator you should simplify those first by adding the numbers together. (An alternate way is using the distributive property to multiply 2 and 9 & 2 and 3. You would then add them together. That would look like this: 2*9 + 2*3)
3. Multiply: =\(\frac{48}{24}\)
Multiply 2 and 12.
4. Simplify: =2
\(\frac{48}{24}\) is equivalent to 2
NOT FRACTION:
If the equation is exactly as you wrote it.
1. Original Equation: 48 / 2(9 + 3) = ?
2. Add: =48 / 2(12)
Add 9 and 3 because when doing equations you want to follow PEMDAS order.
3. Solve left to right: =24(12)
Solve from left to right because when you have division/multiplication in the same equation you want to solve left to right. The same for addition/subtraction. I just did 48 ÷ 2. This will equal 24.
4. Multiply: =288
Just multiply 24 and 12
Depending on how the original equation was set up it will change what your answer is. If either of these equations are not what the original equation looked like please let me know.

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.

At 8 AM, the temperature was −11° F. At 8 PM on the same day the temperature was 36° F. Which expression represents the increase in temperature?
Answers
The reason why D is the correct expression is because the question is asking us the increase from 8 AM to 8 PM, which means we need to find how many degrees the temperature went up. And as shown from the expression in D, (-11 - 36) is -46 and since there is an absolute value in the expression too, it makes the increase 46 degrees.

Which choice when added to | −5 + 7 | will equal zero?

Answers
Answer:
[ 2] − | −5 + 7 |
Step-by-step explanation:
Since we know that | −5 + 7 | is an absolute value, we know that the answer will be positive no matter what.
Step 1) Solve. | −5 + 7 | = 2.
Step 2) Find which other absolute value is equal to -2.
After solving [2], − | −5 + 7 | = -2, we know that the answer is choice 2.
We know this because | −5 + 7 | = 2, however, since it is multiplied by (-), it becomes -2. And 2 + (-2) = 0
We start by simplifying | −5 + 7 |:
| −5 + 7 | = | 2 | = 2
Now we can simplify each of the answer choices:
[2] | +5 − 7 | = | −2 | = 2
[3] | −( −5 + 7 ) | = | 2 | = 2
[4] | 7 − 5 | = | 2 | = 2
We see that only choice [2], when added to | −5 + 7 |, will equal zero:
2 + (−2) = 0
Therefore, the answer is [2] | +5 − 7 |.
Describe the pros and the cons of using the standard form of a line to graph an equation.
Answers
Answer:
The standard form of a line is expressed as Ax + By = C, where A, B, and C are constants and x and y represent the variables. One advantage of using the standard form to graph a line is that it is relatively easy to determine the slope and y-intercept of the line from the constants A and B. This can be particularly useful when trying to analyze the behavior of the line.
Another advantage of using the standard form is that it allows you to easily determine the equation of the line when given a set of points. For example, if you are given the points (2,4) and (3,6), you can use the standard form to find the equation of the line that passes through these points by substituting the coordinates into the form and solving for the constants.
One potential disadvantage of using the standard form is that it can be more difficult to interpret the meaning of the constants A, B, and C in terms of the context of the problem. For example, if the line represents the cost of a product, it may be more intuitive to express the equation in terms of the variables x (the number of units) and y (the cost). In this case, it may be more useful to use the slope-intercept form of the equation, which is expressed as y = mx + b, where m is the slope and b is the y-intercept.

the volume of the right circular cylinder in 144π cubic yards. if h, the height of the cylinder is 4 yards, what is r, the radius of the base?
Answers
If the volume of the cylinder is 144π cubic yards and the height of the cylinder is 4 yards, you can set up the equation:
144π = πr^2 * 4
You can then solve for r by dividing both sides of the equation by 4π:
r^2 = 36
r = 6
Thus, the radius of the base of the cylinder is 6 yards.
Answer:
r = 6
Step-by-step explanation:
The formula for the volume of a cylinder is V = πr^2h,
If the volume of the cylinder is 144π cubic yards and the height of the cylinder is 4 yards it can be written as 144π = πr^2 * 4
You can then solve for r by dividing both sides of the equation by 4π:
r^2 = 36
r = 6
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.
