gemma, a scuba diver, begins a dive on the side of a boat 4 feet above sea level. she descends 28 feet. which integer represents gemmas position with respect to sea level?\n-32\n-24\n24\n32
Answer
Explanation:
Step1: Define initial position
Initial position is 4 feet above sea - level, represented as +4.
Step2: Consider descent
Descent of 28 feet is represented as - 28.
Step3: Calculate final position
Final position = initial position+descent, so (4+( - 28)=4 - 28=-24).
Answer:
-24
