 3(t -7) = 6 \\ 3(t) + 3(-7)\\ 3(-7) = -21 \\ 3t = 3t \\ 3t - 21 = 6 \\Add21: 3t - 21 + 21 = 6 +21 \\ 3t = 21: Divide3 \\  \frac{3t}{3} cancel =  \frac{27}{3}keep \\ t = 9

The pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the
Sergio [31]

Answer:

5.18 pounds per square inch

Complete question:

If the pressure is 6 pounds per square inch when the temperature is 440° F,find  the pressure exerted when the temperature of the gas is 380°F.

Step-by-step explanation:

According to the Gay Lussac's Law:

\frac{P_1}{T_1} =\frac{P_2}{T_2}

where, P and T are the pressure and temperature of an enclosed ideal gas.

Given:

Initial pressure P_1 = 6 pounds per square inch

Initial Temperature T_1=440° F

Final Temperature T_2=380° F

Final Pressure P_2=?

Substituting all values in the formula

\frac{6}{440} =\frac{P_2}{380}

P_2 = \frac{6\times380}{440}

P_2= 5.18pounds per square inch

What is the probability of rolling a three on the first die and a two on the second die?
Neporo4naja [7]
The two rolls of the number cube are independent events because
the result of 1 roll does not affect the result of the other roll.
To find the probability of two independent events, we first find
the probability of each event, then we multiply the probabilities.
We can find the probability of an event using the following ratio:
number of favorable outcomes/total number of outcomes
Since there is only one way to roll a 3 and there are six
possible outcomes, 1, 2, 3, 4, 5, and 6, the probability of rolling a 3 is 1/6.
Since there is also only one way to roll a 2 and there are
six possible outcomes, the probability of rolling a 2 would be 1/6.
Now we multiply the probabilities.
1/6 x 1/6 is 1/36.
So the probability of rolling a 3 and a 2 is 1/36.
