Question

determine the appropriate integer for each situation. type your answers in the boxes below. 1. a fish is 12 meters below the surface of the ocean. what is its elevation? \boxed{} m 2. a sea bird is 28 meters above the surface of the ocean. what is its elevation? \boxed{} m 3. if the bird is directly above the fish, how far apart are they? \boxed{} m

Explanation:

Step1: Fish's Elevation

Elevation below sea level is negative. The fish is 12 m below, so elevation is $-12$ m.

Step2: Bird's Elevation

Elevation above sea level is positive. The bird is 28 m above, so elevation is $28$ m.

Step3: Distance Between Them

Distance is absolute difference. $| - 12 - 28| = | - 40| = 40$ m (or sum of absolute values: $| - 12| + |28| = 12 + 28 = 40$ m).

Answer:

1. $-12$
2. $28$
3. $40$
