Mei releases a lantern for the Lantern Festival. She stands in a field that is 0.5 m belo sea level. The lantern rises 913.9 m. Then the candle in the lantern goes out. The lantern comes down 925.2 m to land on the surface of a lake. What is the elevation o the lake relative to sea level?

The lake is 11.3 m below sea level.

Step-by-step explanation:

Mei's initial position on the field was 0.5 m below sea level.

The lantern rises 913.9 m after its release.

The lantern descends 925.2 m to land on the surface of a lake.

Let the elevation of the lake to sea level be represented by x.

So that;

x = 913.9 - 925.2

  = -11.3

x = 11.3 m below sea level.

Therefore, the lake is 11.3 m below sea level.

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
