what is a/3+4=6? I can't figure it out!

Answers

Answer 1

Answer:

a = 6

Step-by-step explanation:

first try to divide all numbers by 3 and the add 4 to it until you get 6

Answer 2

Answer:

a = 6

Step-by-step explanation:

If you are trying to solve for a then here it is.

a/3 + 4 = 6

subtract 4 from both sides

a/3 + 4 - 4 = 6 - 4

a/3 = 2

multiply both sides by 3

a/3 x 3 = 2 x 3

a = 6

Answers

Answer:4

Step-by-step explanation:

Answer:

x=4

Step-by-step explanation:

8+x=12

We simplify the equation to the form, which is simple to understand  

8+x=12

We move all terms containing x to the left and all other terms to the right.  

+1x=+12-8

We simplify left and right side of the equation.  

+1x=+4

We divide both sides of the equation by 1 to get x.  

x=4

What are the coordinates of the point (-9, 4) after a 90 degree rotation followed by a translation 3 units right?

Answers

(-9,1) should be the answer not completely sure tho

The coordinates of the point (-9, 4) after a 90 degree rotation followed by a translation 3 units right are (8,9) (for clockwise rotation) and (0,-9) (for counterclockwise rotation)

How does rotation by 90 degrees changes coordinates of a point if rotation is with respect to origin?

Let the point be having coordinates (x,y).

Case 1: If the point is in first quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

Case 2: If the point is in second quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

Case 3: If the point is in third quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

Case 4: If the point is in fourth quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

Case 5: For points on axes

You can take that point in any of the two surrounding quadrants. Example, if the point is on positive x axis, then it can taken as of first quadrant or fourth quadrant.

Case 6: On origin

No effect as we assumed rotation is being with respect to origin.

For this case, the point (-9,4) (present in second quadrant) is rotated by 90 degrees.

This rotation can be either clockwise, or counterclockwise.

Thus, for each case, we have:

case 1: Clockwise rotation:

Then (x,y) → (y, -x), therefore, (-9,4) → (4, 9)

case 2: Counterclockwise rotation:

Then (x,y) → (-y, x), therefore, (-9,4) → (-4, -9)

Now, when shifting to right by 4, that means, we're making no changes vertically, but old x-coordinates are increased by 4 to make them shift to right side as value of x increases as we go more and more to the right side with respect to the origin and in defaultly oriented cartesian space.

Thus, we have:

case 1: Clockwise rotation:

After translation of 4 units right:

(4, 9)  → (4+4, 9) = (8,9)

case 2: Counterclockwise rotation:

After translation of 4 units right:

(-4, -9)  → (-4+4, -9) = (0,-9)

Thus, the coordinates of the point (-9, 4) after a 90 degree rotation followed by a translation 3 units right are (8,9) (for clockwise rotation) and (0,-9) (for counterclockwise rotation)

A Ferris wheel accommodate 75 people in 30 minutes . how many people could ride the Ferris wheel in 6 hours? what was the rate per hour?

Answers

Answer: The ferris wheel could accomodate 900 people in 6 hours. The rate per hour was 150 people.

Step-by-step explanation:

To start off we can find the number of people by deciding how many time slots of 30 minutes are in 6 hours. Since 30 minutes is half an hour we just do 2 times 6 which would give us 12. Since 75 people can fit in 30 minutes then we do 12 times 75 for the whole 6 hours which comes out to 900.

Once we have the number of people in 6 hours then we can find the hourly rate. To do this we just take the number of people (900) in the whole time (6 hours) and divide 6 from 900 which would give us the hourly rate of 150.

Answer:

900 people

Step-by-step explanation:

One hour is 60 minutes, and the number of thirty minutes in an hour is two. To get the number of thirty minutes in 6 hours, you would do 2 x 6, which is 12.  After this, you would do 12 x 75 since 75 people ride it in 30 minutes. This equals 900.

The stem-and-leaf plot displays data collected on the size of 15 classes at two different schools.


Mountain View School Seaside School
0 5, 8
9, 8, 2, 0 1 0, 1, 2, 5, 6, 8
8, 7, 6, 5, 5, 4, 4, 3, 1, 0 2 5, 5, 7, 7, 8
0 3 0, 6
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

To calculate the measures of center, we need to find the mean and median for each school.

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
Part A:

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.

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

Step-by-step explanation:

What is the area?

The area is the total space taken up by a flat (2-D) surface or shape. The area is always measured in square units.

To solve for the area of the figure, we can split the figure into 3 shapes. (2 triangles and a rectangle)

An expression you can use to solve for the area of a rectangle and the area of a triangle is:

(Length × width) = area of a rectangle.(Length × width) ÷ 2 = area of a triangle.

Solving for the triangle on the left:

(4 × 3) ÷ 2 =?

Solving what is in the parenthesis:

12 ÷ 2 = 6

Therefore, the triangle on the left has an area of 6 square units.

To solve for the rectangle in the center, we can use this expression:

4 × 3 = 12

Therefore, the area of the rectangle in the center is 12 square units.

Solving for the triangle on the right:

(4 × 2) ÷ 2 =?

Solving what is in the parenthesis:

8 ÷ 2 = 4

Therefore, the area of the triangle on the right is 4 square units.

Adding all of the areas together:

6 + 12 + 4 = 22

Therefore, the total area of the shape is 22 square units.

Add up all the area 22 square units
