The lowest elevation in Lammefjord, Denmark, is 23 feet below sea level. The elevation of the Sea of Galilee in Israel is about

tatyana61 [14]

Answer:

$Sea\ of\ Galilee = -690ft$

Step-by-step explanation:

Given

$Lowest\ Elevation = 23ft$ below sea level

Sea of Galilee = 30 times Lowest in Lammefjord, Denmark

Required

Determine the elevation of the Sea of Galilee

We have that the lowest elevation in Lammefjord is:

$Lowest\ Elevation = -23ft$

It is negative because, the elevation is below sea level.

Calculating the elevation of Sea of Galilee, we have:

Sea of Galilee = 30 times Lowest in Lammefjord, Denmark

$Sea\ of\ Galilee = 30 * -23ft$

$Sea\ of\ Galilee = -690ft$

<em>Hence, the elevation of Sea of Galilee is -690ft or 690ft below sea level</em>

Alekssandra [29.7K]

Answer:

C) No, their slopes are not opposite reciprocals.

Step-by-step explanation:

First we find the slopes.

slope of PQ = (3 - 0)/(7 - 11) = 3/(-4) = -3/4

slope of RS = (-3 - 1)/(6 - 3) = -4/3

product of the slopes = (-3/4) * (-4/3) = 1

The slopes are reciprocals, but they are not opposite reciprocals, so the lines are not perpendicular.
