Kelly has 114 hours to complete 3 chores before leaving for soccer practice. If she spends an equal amount of time on each chore, which of the following could Kay use to find the part of an hour each chore will require?

5/4 times 1/3

Step-by-step explanation:

I got my answer because it said she has 1 1/4 hours to do her 3 chores and there is a mixed number in the problem so convert that mixed number to an improper and you get 5/4. Now the 3 is a whole number so we have to change that to an improper as well and that would be 3/1. Next we have to find the reciprocal of 3/1 and that would be 1/3 then you add a multiplication sign to the problem and it should look like this.

5/4 x 1/3

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.
