Question

Lake Profondo has a depth of 84 feet. Lake Segundo is 5/6
5/6
as deep. What is the elevation at the bottom of Lake Segundo? (Remember, the elevation is below sea level. Account for this in your answer.)(1 point)

Answer 1

To find the depth of Lake Segundo, we first calculate \( \frac{5}{6} \) of the depth of Lake Profondo:

\[
\text{Depth of Lake Segundo} = \frac{5}{6} \times 84 \text{ feet}
\]

Calculating this, we get:

\[
\frac{5}{6} \times 84 = \frac{5 \times 84}{6} = \frac{420}{6} = 70 \text{ feet}
\]

Since the elevation is measured below sea level, we express the elevation at the bottom of Lake Segundo as negative:

\[
\text{Elevation at the bottom of Lake Segundo} = -70 \text{ feet}
\]

Therefore, the elevation at the bottom of Lake Segundo is \(\boxed{-70}\) feet.
