A piano tuner charges $63 for 1.5 hours of work. Which proportion can be used to find x, the number of dollars the piano tuner charges for 4 hours of work?

Step-by-step explanation:

a

the answer choices?

Step-by-step explanation:

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

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.
