Two airplanes leave the same airport. One heads north, and the other heads east. After some time, the northbound airplane has traveled 16 miles. If the two airplanes are 20 miles apart, how far has the eastbound airplane traveled?

answer: its because of life

step-by-step explanation: i dont know

go on the tube you might find some information there

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
