Question

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.
Scientists on a submarine are investigating Earth's magnetic field.
The submarine is at a depth of -116 2/7 feet when the scientists detect a signal frequency from the ocean floor. They dive farther down to a depth of -180 4/7 feet to check the signal. The net change in their depth is
blank feet.

Answer 1

Answer:

The net depth is $-296\frac{6}{7}$

Step-by-step explanation:

Consider the provided information.

The submarine is at a depth of -116 2/7 feet when the scientists detect a signal frequency from the ocean floor. They dive farther down to a depth of -180 4/7 feet to check the signal.

In order to find the depth just add the numbers as shown:

$-116\frac{2}{7}+(-180\frac{4}{7})$

Add the whole numbers.

116+180=296

Combine fractions as shown.

$\frac{2}{7}+\frac{4}{7}=\frac{6}{7}$

The required sum is:

$-116\frac{2}{7}-180\frac{4}{7}=-\left(296+\frac{6}{7}\right)\\-116\frac{2}{7}-180\frac{4}{7}=-296\frac{6}{7}$

Hence, the net depth is $-296\frac{6}{7}$
