For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

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.

Kylie brought 5 pears to soccer practice to share with her teammates. She cuts each pear into thirds. How many slices of pears does she have to share with her teammates? Which equations can you use to solve the problem? Select two equations.
A. 5 × 3 = 15
B. 1/5 × 1/3 = 1/15
C. 1/5 × 3 = 3/5
D. 5 ÷ 1/3 = 15
E. 1/3 ÷ 5 = 1/15
Answers
Answer:
A and D
Step-by-step explanation:
One pear is split into thirds. That means that one pear can become 3 slices. Because you have 5 pears, you have 15 slices. By multiplying 3 (slices) and 5 (pears), we receive the answer of 15 slices.
The answer is A and D.
Step-by-step explanation - Kylie brought 5 pears to practice. Because she cut each of them into thirds, this means that each pear equals 3 slices - therefore making the equation 5 x 3 = 15 and also making the equation 5 ÷ 1/3 because them two both equal 15.

Triangle D has been dilated to create triangle D′. Use the image to answer the question.
Answers
Answer:
To find the scalar value, simply choose one side of D and one did of D’ and divide them to find the scalar. We can verify that we have the correct scalar by performing this division on each related edge. Below I will do D to D’ represented like D/D’:
4.8 / 1.2 = 4
5.2 / 1.3 = 4
3.6 / x = 4
Knowing that the scaling for each edge is 4, we can solve for x.
3.6 / 3 = x
1.2=x
So we know the edges for D are 4.8, 5.2, and 3.6 respectively to D’ scaled by 1/4. So we can determine that the edges for D’ are 1.2, 1.3, and 1.2 respectively to D scaled by 4.
So if we go D’ to D, we scale by 4. If we go D to D’, we scale by 1/4.

Find the surface area of a top open cylinder
12 in radius
2 in height
Answers
The surface area of the top open cylinder is 6810.149 sq.cm.
A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.
Surface area of a cylinder = Base area + Lateral area
Base area of a cylinder = 2 × π × r²
Lateral area of a cylinder = (2 × π × r) × h
Therefore, here base area of a cylinder = 2× π × 12²
= 5837.27 sq.cm.
And, lateral area of a cylinder = (2 × π × 12) × 2
= 972.8784 sq.cm.
Therefore, total surface area of a cylinder = 5837.27 + 972.8784
= 6810.149 sq.cm.

Sanjay went blueberry picking along a 3-mile walking path. He picked blueberries steadily along the walk. When he was finished, he had collected 50 ounces of blueberries.
How many ounces of blueberries did Sanjay pick each mile?
Write your answer as a proper fraction or mixed number.
Answers
Answer:
16 2/3 per a mile
Step-by-step explanation:
50 ounces of blueberries/3 miles = 16.666 repeated
16.666 repeated = 16 2/3 ounces/mile
Answer: Sanjay picked 16.66 ounces each mile
Step-by-step explanation:
For this exercise let "x" represents the amount of ounces of blueberries that Sanjay picked each mile, along the 3-mile walking path.
According to the information given in the exercise, you know that Sanjay picked a total amount of 50 ounces of blueberries along the walking path.
Then, knowing that the length of that walking path is 3 miles, you can set up the following proportion:
\(\frac{3}{50} = \frac{1}{x}\)
Now, the next step is to solve for "x" in order to find its value.
You get that this is:
\((x)(\frac{3}{50} )=1\\\\x=(1)(\frac{3}{50} )\\\\x=16.66\)
Therefore, knowing the value of "x", you can conclude that Sanjay picked 16.66 ounces of blueberries each mile.
16.66 = 16 2/3

Each month, Margie's pets need 3 bags of dog food and 2 bags of cat food. How many bags of pet food would she need for 4 months?Which equation shows how to solve this problem?
Answers
Answer:
20 bags; 3 x 4 + 2 x 4 = y bags of pet food
Step-by-step explanation:
4 x 2 = 8 bags of cat food
4 x 3 = 12 bags of dog food
12 + 8 = 20 bags in total
So, we now know how many bags of pet food Margie needs for 4 months. To write an equation based on this, we need to include how many times Margie would buy each type of pet food. Which, in this case, would be 4 months. So, 4 months times 2 bags of cat food equals 8 bags of cat food, and 4 months times 3 bags of dog food equals 12 bags of dog food. This all together equals y amount of bags for pet food. In conclusion, 3 x 4 + 2 x 4 = y bags of pet food.
Answer:
20 bags of pet food in 4 months
Step-by-step explanation:
3*4=12
2*4=8
8+12=20
Dog food: Multiply 3 by 4 since 4 months which equals 12.
Cat food: Next multiply 2 by 4 since 2 bags in a month which equals 8
Finally add 8 and 12 and you will get 20 bags of pet food in 4 months.

what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answers
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.
PLEASE MARK BRAILYISTT :D
Answer:

Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6.

Answers
Answer:
False
Step-by-step explanation:
The first part of the statement is correct with it saying to have an open circle on -3, but the shading should go on the right because x is bigger than -3. When you picture a number line, the numbers on the right of -3 are bigger than the numbers on the left.
The statement " To graph the inequality x > -3, draw an open circle on -3 and shade to the left" is wrong.
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.
The first part of the statement is correct, as it states that an open circle should be placed on -3, but the shading should be placed on the right because x is greater than -3. On a number line, the numbers to the right of -3 are larger than the numbers to the left.
