Lake Profondo has a depth of 84 feet. Lake Sengundo is 5/6 as deep. What is the elevation at the bottom of Lake Sengundo?
The depth of Lake Sengundo is 5/6 * 84 feet = <<5/6*84=70>>70 feet.
The elevation at the bottom of Lake Sengundo is 0 - 70 feet = <<0-70=-70>>-70 feet. Answer: \boxed{-70}.
To find the depth of Lake Sengundo, we need to calculate 5/6 of the depth of Lake Profondo.
First, let's find 5/6 of 84 feet:
(5/6) * 84 = (5 * 84) / 6 = 420 / 6 = 70 feet
Therefore, the depth of Lake Sengundo is 70 feet.
To find the elevation at the bottom of Lake Sengundo, we need to subtract this depth from the surface elevation.
However, since the question does not provide the surface elevation of Lake Sengundo, we cannot calculate the elevation at the bottom of the lake given the information provided.
To find the elevation at the bottom of Lake Sengundo, we first need to determine the depth of Lake Sengundo.
Since Lake Profondo has a depth of 84 feet, Lake Sengundo is 5/6 as deep. To calculate the depth of Lake Sengundo, we'll multiply the depth of Lake Profondo by 5/6.
Depth of Lake Sengundo = (5/6) * Depth of Lake Profondo
Depth of Lake Sengundo = (5/6) * 84 feet
To simplify the calculation, let's convert the fraction 5/6 to a decimal. Dividing 5 by 6 gives us approximately 0.8333.
Depth of Lake Sengundo = 0.8333 * 84 feet
Now, let's calculate the depth of Lake Sengundo using a calculator:
Depth of Lake Sengundo ≈ 69.9972 feet
Therefore, the elevation at the bottom of Lake Sengundo is approximately 69.9972 feet.
