For nitrogen to be a liquid, its temperature must be within 12.78 °f of –333.22 °f. the equation |x 333.22 | = 12.78 can be used
2 answers:
The maximum temperature is -320.44 and the minimum temperature is -333.22.
<h3>How is the temperature variation calculated?</h3>In this case, there was an increase of 50 °C in the temperature of this object. We say that the temperature variation suffered by the body was 50°C, and this can be determined mathematically through the difference between the final value and the initial temperature value (60 – 10 = 50).
In this case, we have:

The speed of the cart after 3 seconds of Low fan speed is equal to 54 cm/s.
<h3>How to calculate the speed?</h3>Mathematically, speed can be calculated by using this formula;
Speed = distance/time
At Low fan speed after 3 seconds, the distance covered is 162 cm:
Speed = 162/3
Speed = 54 cm/s.
At Medium fan speed after 5 seconds, the distance covered is 600 cm:
Speed = 600/5
Speed = 120 cm/s.
At High fan speed after 2 seconds, the distance covered is 128 cm:
Speed = 128/2
Speed = 64 cm/s.

The equation expressing the statement "y varies directly as x" is
Explanation
The statement that varies directly as
is analogous to saying that the ratio of
to
is constant. In other words, when
increases,
likewise increases and that when
decreases,
decreases proportionally.
Mathematically, we express the relationship that the ration of is to
is constant is expressed as;
where
is the constant of proportionality.
We can then solve the relationship for to determine the correct form of the relationship as shown below,
