A paper sheet is cut 28 inches to the nearest inches. Find the maximum and minimum length of the patient possible.
aliina [53]

Answer:

  • max: 28.5 inches
  • min: 27.5 inches

Step-by-step explanation:

If the actual dimension were different from 28 inches by more than 1/2 inch, it would be reported as a different dimension. So, the minimum that will be reported as 28 is 27.5. The maximum that will be reported as 28 will be 28.4999999.... ≈ 28.5

The maximum and minimum length of the sheet are 28.5 inches and 27.5 inches, respectively.
