Abee beats its wings 250 times each second. what is the average time for a single beat of a bee's wing?

for each second the bee beats its wings 250 times.

we are asked to find the average time taken for a single beat of a bees wing

the time taken for 250 beats - 1 second

average time for a single beat - 1 second/ 250 beats = 1/250 seconds/beat

answer is 0.004 seconds per beat

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.
