HEL Nitrogen is a gas at certain temperatures under normal conditions. These temperatures (t),
in degrees Celsius (°C) are represented by the inequality t > -196. Which best describes
the meaning of the inequality?
(2 points)
A.
Nitrogen is a gas only if the temperature is below -196(°C)
B.
Nitrogen is a gas only if the temperature is above -196(°C)
C.
Nitrogen is a gas only if the temperature is at or below -196(°C)
D.
Nitrogen is a gas only if the temperature is at or above - 196(°C)

B

Step-by-step explanation:

The inequality says "t is greater than -196".

We can assume 't' means temperature.

With water, the gas state is warmer than the other states. (Steam is hotter than liquid water or water frozen solid.)

I took basic chemistry and I can tell you it is the same for other substances. - The gas state is the warmest.

So we can assume that Nitrogen is a gas at the warmer temperature.

Thus, we are looking for the statement that says Nitrogen is a gas when its temperature is greater than -196° Celsius.

B is the only one that matches.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
