Answer is B
Step-by-step explanation:
You have the side opposite the angle and the Hypotenuse so use soh
Sine(x) = opposite/Hypotenuse
Sine(x) = 9/19
X = sin-1(9/19) - - - - - here the - 1 is to the power of
X= 28,27371363
X= 23,3
V15 because you increase the numerical value by 3. Also, the letter is going from z (the end of the alphabet) to the letter before.
27 dollars minus 6 for the ice leaves 21 for hot dogs.. hot dogs are 3 each and 21 dollars left it would be 21 divided by 3 which equals 7
Answer: The initial volume is 593.76mL
Step-by-step explanation:
As you do not say anithing about the pressure, i guess that the pressure remains constant.
If the gas is an ideal gas, we have:
P*V = n*R*T
where P is pressure, n is number of moles and R is a constant.
Now, initially we have:
P*Vi = n*R*315°C
finally we have:
P*825mL = n*R*452°C
Now we can take the quiotient of those two equations and get:
(P*Vi)/(P*852mL) = (n*R*315°C)/( n*R*452°C)
Now we have:
Vi/852mL = 315/452
Vi = (315/452)*852mL = 593.76mL
So when we expand the gas at constant pressure, we increase the temperature.
