use the information given in the exercise to answer the question.

assume that depths below the oceans surface are represented by negative values and heights above the oceans surface are represented by positive values. tom and cassie are in the bahamas. they are at 40 feet below the surface of the ocean.

what is their depth? (include units in your answer. more information.)
their depth is $square$.

they dive another 30 feet. now what is their depth? (include units in your answer. more information.)
their depth is now $square$.

Explanation:

Step1: Calculate 1 PM temperature

$\text{Final Temp} = -6 + 40 = 34$

Step2: Initial ocean depth (below surface)

$\text{Initial Depth} = -40 \text{ feet}$

Step3: Depth after diving 30 more feet

$\text{New Depth} = -40 + (-30) = -70 \text{ feet}$

Answer:

1. 34 °F
2. -40 feet
3. -70 feet
