Question

Stretch 2

The deepest point in the ocean is the Marianas
Trench in the Pacific Ocean at about 6.9 miles
below sea level. The highest point in the world is
Mount Everest in the Himalayan Mountains at
about 5.5 miles. Plot each elevation as an
rational number on a number line, and use
absolute value to determine the number of miles
between the deepest point in the ocean and the
highest point in the world.
50 points

Answer 1

12.4 miles

Explanation:

The absolute value is the distance of a number from 0 regardless of which direction from 0 the number is located. The absolute value of a real number is always the non-negative value of the real number even if the real number in question is negative.

In this scenario, we are being asked to find and add the absolute values of -6.9 and 5.5.

| -6.9 | + | 5.5 | =

| -6.9 | = 6.9 *Do not forget that absolute values are never negative even when you are finding the absolute value of a negative number.

| 5.5 | = 5.5

6.9 + 5.5 = 12.4 miles

~Hope this helps!~
