Answer:
Katie made a mistake. P = (nRT)/P is the correct equation, not V = PnRT
Step-by-step explanation:
The equation for the ideal gas law is PV = nRT, where P is pressure, V is volume, n is the moles of gas, R is the gas constant, and T is the temperature, in Kelvin.
Solving for V:
PV = nRT
V = (nRT)/P
Katie did not solve the equation corretly. To move V from the left to the right side of the equation, she needed to divide both sides by P:
PV = nRT
PV/V = (nRT)/P
P = (nRT)/P is the correct equation
Gina is taller. The difference between both of their heights is 4 cm.
This is in slope intercept form or y=Mx+b
y= 5/4x + 3/4 you can also turn them into decimals. Hope this helps good luck!
Answer:
it would be any number that is less that ten but greater than 5
Answer:
she needs 25 sticks of butter
Step-by-step explanation:
From the question, we are told that for each additional butter stick, she can bake 1 cake
She wants to bake a total 49
We already have 24 baked
So what is left would be;
49-24 = 25 cakes
So she needs exactly this number of butter sticks
