Question

4a. an emperor penguin’s dive can reach more than 1,600 feet deep. write an inequality to represent how deep a penguin can dive using the variable d.

Explanation:

Step1: Define the variable

Let \( d \) represent the depth of the penguin's dive (in feet).

Step2: Translate the phrase to inequality

The phrase "more than 1,600 feet deep" means the depth \( d \) is greater than 1600. In inequality notation, this is written as \( d > 1600 \).

Answer:

\( d > 1600 \)
