Answer : The correct option is, (d) inversely proportional to volume and directly proportional to the kelvin temperature
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

Charles' Law : It is defined as the volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.

Combined gas law : It is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,

or,

From the above information we conclude that the pressure exerted by a gas is inversely proportional to volume and directly proportional to the kelvin temperature.
Hence, the correct option is, (d)
Answer:
A. She can run the same distance in a shorter amount of time.
Explanation:
Speed can be computed with the formula:

Where:
v = speed
d = distance
t = time
So if you look at the formula, distance there tells you how far an object has traveled, and the time tells us how long it took to cover that distance. As you can see, speed and time are <u>inversely proportional. </u>This means that as one goes up, the other goes down. So if we reduce time travelling a certain distance, the speed increases.
Answer:
12.
1 + 2 + 1 = 4 + 1 + 2 + 1 + 4 = 12 = 4 + 1 + 2 + 1 + 4 = 1 + 2 + 1
