Miche found that most helicopters fly at speeds of less than 270 kilometers per hour. Her work is shown below. s > 270 A numb
almond37 [142]

Answer:

  • The inequality should be s<270.
  • The number line should be shaded to the left.

Step-by-step explanation:

Miche found that most helicopters fly at speeds of less than 270 kilometers per hour.

If s=speed of the helicopters

  • Then: s<270

Representing this on a number line:

  • We have an open circle at 270.
  • Everything to the left of the circle is shaded.

Since the options are not given, I would list the mistakes made by Miche.

  • The inequality should be s<270.
  • The number line should be shaded to the left.
