Sasha runs at a constant speed of 3.8 meters per second for 1/2 hour. Then walk at a constant speed of 1.5 meters per second 1/2 hour. How far did Sasha run and walk in 60 minutes? How far did run and walk in 60 minutes

your answer is d 2,500

step-by-step explanation:

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.
