Sue earns $6 an hour walking her neighbor's dog.

Part A: Create two variables and determine which is dependent and which is independent for this situation. (4 points)

Part B: List three ordered pairs to show the values of the two variables. (3 points)

Part C: Write an equation to represent the relationship between the two variables. (3 points)

Answers

is that all that the question says ?

(A) The independent variable is time because it is something that can be controlled and changed by the person walking the dog.

(B) Three ordered pairs are (1, 6), (2, 12), (0.5, 3).

(C) The equation is:

Money earned = 6t

What is an expression?

In mathematics, an expression is a combination of numbers, variables, and operations that are grouped together to represent a mathematical statement.

Part A:

In this situation, the two variables are:

Independent variable: Time (in hours) spent walking the dog

Dependent variable: Amount of money earned (in dollars)

The independent variable is time because it is something that can be controlled and changed by the person walking the dog. The dependent variable is the amount of money earned because it is directly affected by the amount of time spent walking the dog.

Part B:

Here are three possible ordered pairs to show the values of the two variables:

(1, 6) - Sue earns $6 for walking the dog for 1 hour.

(2, 12) - Sue earns $12 for walking the dog for 2 hours.

(0.5, 3) - Sue earns $3 for walking the dog for half an hour (30 minutes).

Part C:

The relationship between the two variables can be represented by the equation:

Money earned = Hourly rate x Time spent walking

In this case, the hourly rate is $6 and the time spent walking is represented by the variable "t". Therefore, the equation is:

Money earned = 6t

where "t" is the time (in hours) spent walking the dog and "6t" is the amount of money (in dollars) earned for that time.

Gracie’s bill at a restaurant is $15. Sales tax is 6% and she plans to leave a 20% tip (on the total after tax is added). What is the total amount of money she’ll pay, including tax and tip?

Answers

sales tax would be 0.90 then add the 20% would be 3.00 so 15 + 0.90 + 3 = ur answer

Answer:

She will pay $19.08

Step-by-step explanation:

Upon graduating, he went on to Cambridge University for postgraduate studies|in cosmology (the study of the universe). At age 21, Stephen started to stumble and drop things. His speech became slurred. Doctors diagnosed him with ALS, a disease that left him mostly paralyzed. His illness did not affect his brilliant mind. Stephen did not let his disability keep him from what he wanted to accomplish in life. He got married and had children. He went on to become a world-renowned physicist and best-selling author.
