You work as an assistant coach on the university swim team and earn $14 per hour. one day, you decide to skip the hour-long practice and go to the local carnival instead, which has an admission fee of $9. the total cost (valued in dollars) of skipping practice and going to the fair (including the opportunity cost of time)

  $23

Step-by-step explanation:

You lose $14 in wages and it costs you an additional $9 to get into the fair. The cost to you of trading team practice for the fair is $14 +9 = $23.

___

You can see this cost if you compare your net worth after your payment for going to team practice, versus your net worth after admission to the fair. In the first case it is ...

  base-value + $14

In the latter case, it is

  base-value - $9

The difference of these is

  (base-value -$9) -(base-value +$14) = -$9 -14 = -$23

Skipping practice effectively reduces your net worth by $23 from what it would have been had you not skipped practice. That is your cost of going to the fair.

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.

step-by-step explanation:

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
