Answer:

A = plane

B = whale

C = sunken ship

Step-by-step explanation:

The given vertical number line is modelling the positions of objects and animals in relation to sea level.

Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.

From inspection of the given number line:

Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.

We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.

We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

A is plane b is whale c is sunken ship

Jade buys a blouse and a skirt for 34 of their original price. She pays a total of $31.50 for the two items. If the original price of the blouse is $18, what is the original price of the skirt?

Part A

Which equation represents the situation?
0.75s = 31.50
34(18s) = 31.50
0.75(s + 31.50) = 18
34(18 + s) = 31.50
Part B

Use the Distributive Property to solve the equation.
Enter your answer in the box.

$

Answers

Answer:

`Part A:

D. 3/4(18 + s) = 31.50

Part B:

$36

Step-by-step explanation:

I think 34 is 3/4, is that right?

here, s is the cost of the skirt

Part A: The answer would be:

3/4(18) + 3/4(s) = 31.5 =

3/4(18 + s) = 31.5

Part B: 3/4(18) + 3/4(s) = 31.5

4.5 + 3/4s = 31.5

Subtract 4.5 from both sides:

3/4s = 27, 27 is the cost of the skirt now, but we need the original price.

multiply both sides by 4/3:

s = 36

The equation m = 3b represents the time in minutes (m) it takes a chef to cook a certain number of bacon cheeseburgers (b).

Determine the constant of proportionality.

A. 3

B. 6

C. one third

D. 1

Answers

For the given equation:

m = 3b

The constant of proportionality is 3, so the correct option is A.

How to determine the constant of proportionality?

After a small search on the internet, I've found that this question asks for the constant of proportionality.

Remember that a proportional relation is of the form:

y = k*x

Where k is the constant of proportionality, and x and y are the variables.

Here the relation is:

m = 3*b

Where m and b are the variables, then the remaining coefficient is the constant of proportionality, which is 3.

In this way, we can see that the correct option is A.

The box plot shows the number of jumping jacks completed in a workout class by the class members. A box plot uses a number line from 14 to 54, with tick marks every one unit. The box extends from 26 to 49 on the number line. A line in the box is at 40. The lines outside the box end at 15 and 52. The graph is Jumping Jacks Completed, and the line is labeled Number of Jumping Jacks. Which of the following lists the range and IQR for this data? The range is 23, and the IQR is 37. The range is 40, and the IQR is 37. The range is 40, and the IQR is 23. The range is 37, and the IQR is 23.

Answers

To determine the range and IQR (interquartile range) based on the given box plot, let's first define these terms:

- Range: The range is the difference between the maximum and minimum values in a data set.
- IQR: The IQR is the range of the middle 50% of the data values. It is calculated by finding the difference between the third quartile (Q3) and the first quartile (Q1).

In the given box plot:

- The lines outside the box represent the minimum and maximum values.
- The box represents the middle 50% of the data, with the line inside the box representing the median (or second quartile, Q2).
- The distance between the lower whisker and the bottom edge of the box represents the first quartile (Q1), and the distance between the upper whisker and the top edge of the box represents the third quartile (Q3).

Based on the information provided in the box plot, we can determine the range and IQR as follows:

- The minimum value is represented by the lower whisker, which ends at 15.
- The maximum value is represented by the upper whisker, which ends at 52.
- Q1 is located at the bottom edge of the box, which is 26.
- Q3 is located at the top edge of the box, which is 49.

Now we can calculate the range and IQR:

- Range: maximum value - minimum value = 52 - 15 = 37
- IQR: Q3 - Q1 = 49 - 26 = 23

Therefore, the correct statement is:

The range is 37, and the IQR is 23.

Answer:

The range is 37, and the IQR is 23.

Step-by-step explanation:

A box plot (also known as a "box and whisker plot"), is a graph displaying the distribution of a set of data based on a five-number summary.

Five-number summaryMinimum value is at the end of the left whisker.Lower quartile (Q₁) is the left side of the box.Median (Q₂) is the vertical line inside the box.Upper quartile (Q₃) is the right side of the boxMaximum value is at the end of the right whisker.

From the given information, the five-number summary of the Jumping Jacks box plot is:

Minimum = 15Lower quartile (Q₁) = 26Median (Q₂) = 40Upper quartile (Q₃) = 49Maximum = 52

Range

The range is the difference between the maximum and minimum values. Therefore, the range for the data is:

$\sf Range = 52 - 15 = \boxed{\sf 37}$

Interquartile range (IQR)

The IQR is the difference between the upper quartile and the lower quartile. Therefore, the IQR for the data is:

$\sf IQR = Q_3 - Q_1 = 49 - 26 = \boxed{\sf 23}$

Summary

The range is 37, and the IQR is 23.

Banana Cupcakes
makes 10 cupcakes

1 cup granulated sugar

cup vegetable oil

1 large egg

4 tablespoons sour cream

2 medium-sized ripe bananas, mashed

1 cups all-purpose flour

1 teaspoon baking soda

teaspoon salt

1 teaspoon vanilla extract

pinch of nutmeg

You will use the recipe above to answer the following questions:

This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?

Answers

Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.

Step-by-step explanation:

Here we have a recipe that works for 10 serves.
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.

The correct statements are:

6 is a coefficient.The expression has two variable terms.8 is a constant.This expression is the sum of three terms.

Explanation:

The coefficient is the numerical factor that is multiplied by a variable term. In this case, 6 is a coefficient that is associated with a constant term.Variable terms have a variable factor. In this case, the expression has two variable terms (8y^2 and 3y).A constant is a term that has no variable factor. In this case, 8 is a constant term.The expression has three terms: 8y^2, 3y, and 6.

Please Determine the value of the number being described. When 10 is subtracted from 3 times the number, what is the result if the number is being divided by 2? What is the number?

Answers

Answer:

x = 20/3

Step-by-step explanation:

When 10 is subtracted from 3 times the number and the number is divided by 2, what is the number? ---> 3 ( x / 2) - 10 = 0

3 ( x / 2) - 10 = 0

3( x / 2 ) = 10

3x / 2 = 10

3x = 10 * 2

3x = 20

x = 20/3

Solution: We have number 10 which is subtracted from 3 times the number and the number is divided by 2.
let the number be x, then
3 ( x/2 ) - 10 = 0
or, 3 ( x/2 ) = 10
or, x/2 = 10/3
or, x * 3 = 10* 2
or, 3x = 20
∴ x = 20/3
