Final answer:
The various latitudes of locations in the United States can be represented by the inequality 71°23' ≤ latitude ≤ 18°55'.
Step-by-step explanation:
The latitudes of locations in the United States can be represented by an inequality. Since the northernmost point is Point Barrow at 71°23' latitude, we can represent the latitudes of locations in the United States using the inequality \71°23' \leq \latitude \leq 18°55'.
For example, a location with a latitude of 45° would satisfy the inequality because it falls between the northernmost and southernmost points of the United States.
So, the inequality \71°23' \leq \latitude \leq 18°55' represents the various latitudes of locations in the United States.
