A compound Machine is 2 machines that work together in order to make a task easier.
Answer:
93 o 39.
Explanation:
Hola.
En este caso, podemos resolver este problema por medio del planteamiento de las siguientes ecuaciones:
1. Definimos <em>x</em> como el primer dígito y <em>y</em> como el segundo, por lo tanto, como su suma es 12, escribimos:
<em>x</em> + <em>y</em> = 12
2. Ahora, dado que el primer dígito, x es el triple del segundo, escribimos:
<em>x</em> = 3 <em>y</em>
De este modo, podemos resolver para <em>y</em>:
3 <em>y</em> + <em>y</em> = 12
4 <em>y</em> = 12
<em>y</em> = 12 / 4
<em>y</em> = 3
Y para <em>x</em>:
<em>x</em> = 3 <em>y</em>
<em>x</em> = 3 * 3
<em>x</em> = 9
Así, el número puede ser 93 o 39.
¡Saludos!
Answer:
For a gas held at constant temperature, we can apply Boyle's law, which states that the product between the gas pressure and its volume is constant:

where
P is the pressure
V is the volume
As we see from the equation, P and V are inversely proportional to each other: this means that when the volume is decreased, the pressure increases, and vice-versa. The reason for that is that when the volume is decreased, the gas is compressed, so the molecules of the gas come closer to each other, so they collide more frequently with the wall of the container, exerting therefore a greater pressure.
