Write the numbers in the following examples using the proper signs. (1) A submarine is at a depth of 512 meters below sea level. (2) The height of Mt Everest, the highest peak in the Himalayas, is 8848 meters. (3) A kite is flying at a distance of 120 meters from the ground. A) -512 m, 8848 m, 120 m B) +512 m, +8848 m, +120 m C) -512 m, -8848 m, -120 m D) 512 m, 8848 m, 120 m

Answer 1

The correct answer is C) -512 m, -8848 m, -120 m.

Explanation:

(1) A submarine at a depth of 512 meters below sea level would be represented as -512 m. The negative sign indicates that the depth is below sea level.

(2) The height of Mt Everest, which is 8848 meters, would be represented as -8848 m. Again, the negative sign indicates that the height is above sea level.

(3) A kite flying at a distance of 120 meters from the ground would be represented as -120 m. The negative sign indicates that the distance is above the ground.

Therefore, the correct signs for the numbers in the examples are -512 m, -8848 m, -120 m.
