In meteorology, the 540 line is *roughly* where you see freezing temperatures.
A more roundabout explanation: 540 = 5400 meters = the distance between where atmospheric pressure is 1000mb and 500mb, the lower half of the atmosphere in which we live. The thicker this layer, the warmer the air is. It's not so critical in other places; on the West Coast, it's the 528 line, at higher elevations, this thickness is greater because of the pressure compensation.

Whats the answer everyone?
Fossils in layer 5 are less than 540 million years old.
Ediacaran fauna are the fossil animals found in rocks dated around 650-540 million years ago, just before the Cambrian period.
The answer will depend on the temperature of the liquid water and the pressure.

36% of 540 = 36% * 540 = 0.36 * 540 = 194.4
12% of 540= 12% * 540= 0.12 * 540= 64.8
85% of 540= 85% * 540= 0.85 * 540= 459
28% of 540= 28% * 540= 0.28 * 540= 151.2
18% of 540= 18% * 540= 0.18 * 540= 97.2
37% of 540= 37% * 540= 0.37 * 540= 199.8
540
50% of 540= 50% x 540= 0.50 x 540= 270
It is: 0.30*540 = 162
Oklahoma does share the longest state line with Texas. The length of this line is around 540 miles long, following the path of the Red River.
