Question

HELP ME PLEASE LOL

In this discussion board, you will be asked to apply your understanding of compound inequalities to things and activities in the world around you. Below you can see two examples of real-life "and" and "or" situations.

An example of a compound inequality involving the word "and" can be thought of as an elevator. An elevator for a building must move between (and include) floor zero and the top floor. For a 20-floor apartment building with no basement, we can represent the elevator reaching all the floors between the ground floor and the top floor as . In words, we can say that the elevators must be able to reach greater than or equal to the ground floor and less than or equal to the 20th floor.
An example of a compound inequality involving the word "or" can be thought of as a car burning fuel. A car burns more gasoline when it's going either really slow or really fast. When we look at when it is most expensive to drive, the car must be going below 40 miles an hour or above 70 miles an hour. The inequality to represent this is x<40 or x>70.
For this discussion board, it is your task to write your own real-life examples of "and" and "or" situations (one of each). Your situation must be unique, meaning that the examples in your post must be different from ideas your classmates posted.

Your post must include the following for each:

In detail, describe the thing or activity that you feel is an "and" or an "or" situation.
Write your inequality in symbols.
Write your inequality in words.

Answer 1

Explanation:

for the "AND" you can maybe use: a laboratory thermometer is used to measure temperatures between (and include) -10 degrees Celsius and 110 degrees Celsius. the thermometer must be able to reach < -10 degrees and > 110 degrees.

for the "OR": a person can burn calories through exercise by either walking or running. when observed how they burn the most calories, they must be walking for over 60minutes or running for less than 20minutes. the inequality to represent this is x>60, x<20.

hope this helps, I've never seen a maths question like this before, are you doing applied maths?
