Question

Miche found that most helicopters fly at speeds of less than 270 kilometers per hour. Her work is shown below. s > 270 A number line going from 260 to 285. An open circle is at 270. Everything to the right of the circle is shaded. Which mistakes did she make? Check all that apply.

Answer 1

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.
