A high school student council has one representative from each grade (6-11). If each of the members of the council is capable of holding any office, if it is known that the president must be a tenth degree or an eleventh degree, the number of ways in which the president, vice president, and secretary can be selected are

1. minimum

2. 6400

3. eight

hope this !

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.
