Triangle MNO is reflected over the x-axis and then translated up 4 and right 3. On a coordinate plane, triangle O M N has points (1, 3), (2, 1), (negative 1, 2). Triangle O prime M prime N prime has points (4, 1), (5, 3), (2, 2).
How can the transformation be amended such that the translation can occur before the reflection and have the image remain in the same
position?

Answers

Answer:

Option A. Translate the pre-image down 4 and right 3 and then reflect the figure over the x-axis

Step-by-step explanation:

The required translation is to translate triangle MNO 4 units down and 3 units left. Option A is correct.

What is the transformation of geometry over the coordinate plane?

Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Felix Klein introduced transformational geometry, a fresh viewpoint on geometry, in the 19th century.

Here,
Triangle MNO is reflected over the x-axis and then translated up 4 and right 3.
On a coordinate plane, triangle OMN has points (1, 3), (2, 1), and (-1, 2). Triangle O'M'N' has points (4, 1), (5, 3), (2, 2).

Before reflection, the translation of MNO is given as 4 units down and 3 units left.

Thus, the required translation is to translate triangle MNO 4 units down and 3 units left. Option A is correct.

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?

2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100

Answers

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

2 over 8 equals j over 18

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

2 over 8 equals j over 18

A lake fishing map is laid out on a coordinate plane with each unit equal to 1 mile. The boat is launched from the point (−6, 0) and goes to point (−6, −6) to fish. From there, the boat travels to (0, 0) to fish and then goes back to the launch point.

Determine the total number of miles traveled. Round to the nearest whole number.

72 miles
20 miles

6 miles

Answers

6 miles I think I hope this helped

The total distance travelled in the journey is 20 mile.

What is distance?

Distance is the total movement of an object without any regard to direction.

Given that, A lake fishing map is laid out on a coordinate plane with each unit equal to 1 mile. The boat is launched from the point (−6, 0) and goes to point (−6, −6) to fish. From there, the boat travels to (0, 0) to fish and then goes back to the launch point.

The total distance is divided into three parts, obtained as follows:

First part: From point (-6,0) to point (-6,-6).

Second part: From point (-6,-6) to point (0,0).

Third part: From point (0,0) back to the launch point of (-6,-6).

The generic notation of two points is given as follows:

(x1,x2), (y2.y1)

The distance between two points is then given by the equation presented as follows:

D = √(x2-x1)²+(y2-y1)²

Therefore, each distance in this problem is given as follows:

First part: 6 miles.

Second part: 8.48 miles.

Third part: 6 miles.

The total distance is the sum of each distance, hence it is given as follows:

6+8.48+6 = 20.48 ≈ 20

Hence, The total distance travelled in the journey is 20 mile.

A carpenter had a board that was 2 yard long. He used 18 inches on a project. How many feet long was the board when he was done?

2 1/2 feet

4 1/2 feet

3 3/4 feet

1 1/4 feet

Answers

Answer:

4 1/2 ft

Step-by-step explanation:

1 yard = 36 inches

2 yards = 2 × 1 yard = 2 × 36 inches = 72 inches

The board started with a length of 72 inches.

He used 18 inches.

72 in. - 18 in. = 54 in.

He has 54 in. left.

Now we convert 54 in. to ft.

1 ft = 12 in.

54 in. × (1 ft)/(12 in.) = 4.5 ft = 4 1/2 ft

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30

Since the area is equal to length times width, and you know your area has to be 30, you can plug in your values like this:

(2x+7) x = 30

you can distribute to make this easier

2x^2 + 7x = 30

you can plug this into quadratic formula by setting the equation =0, so:

2x^2 +7x -30 = 0

where 2x^2 = a
7x = b
and -30 = c

you can plug this into your calculator and get an answer of

X = 2.5

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

Answers

Answer: Please refer below mentioned explanation.

Step-by-step explanation:

Part A:

For Bay Side School: To find the median, we arrange the data in ascending order: 0, 0, 2, 3, 4, 5, 5, 5, 6, 6, 8, 8, 8 There are 13 data points, so the median is the 7th value, which is 5.

To find the mean, we sum up all the data points and divide by the number of data points: Mean = (0 + 0 + 2 + 3 + 4 + 5 + 5 + 5 + 6 + 6 + 8 + 8 + 8) / 13 = 66 / 13 ≈ 5.08

For Seaside School: To find the median, we arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 5, 5, 5, 6, 7, 7, 8, 8 There are 15 data points, so the median is the 8th value, which is 5.

To find the mean, we sum up all the data points and divide by the number of data points: Mean = (0 + 0 + 0 + 1 + 1 + 2 + 2 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8) / 15 = 57 / 15 ≈ 3.80

Part B:

For Bay Side School: Range = Maximum value - Minimum value = 8 - 0 = 8

For Seaside School: Range = Maximum value - Minimum value = 8 - 0 = 8

Part C:

Based on the measures of the center, Bay Side School has a higher mean and median compared to Seaside School. This suggests that, on average, Bay Side School tends to have larger class sizes than Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice. Additionally, both schools have the same range of 8, indicating that the spread of class sizes is similar between the two schools.

Answers

Answer:

1. no, y = 5 + 3w

no, e = h + 2

Step-by-step explanation:

Using the principle of proportional relationship to model the two tables, we can infer that, the first first table is proportional while the second isn't.

Clara's arrangement :

White (w)Yellow (y)

Testing if relationship is proportional :

y = kw

5 = 3k

$ k = \frac{5}{3}$

Yes, the relationship is proportional $ y = \frac{5}{3}w$

Hector's arrangement :

White (h)Yellow (e)

The number of yellow flowers surpasses the number of white flowers by a constant value of 2.

Hence, the relationship can be modeled thus ;

e = h + 2

Therefore, the relationship is not proportional.

The area of Rectangle in centimeters is 2348.4 cm²

What is the Area of a Rectangle?

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

The length of the rectangle = 26 inches

= 26 x 2.54

= 66.04 centimeters

The width of the rectangle = 14 inches

= 14 x 2.54

= 35.56 centimeters

The area of the rectangle = length of the rectangle x width of the rectangle

So ,

The area of the rectangle = 66.04 centimeters x 35.56 centimeters

= 2348.3824 cm²

≈ 2348.40 cm²
