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
Answer:
y = -2/3x
Step-by-step explanation:
To write in y=mx+b form, you need the y-intercept (b) and the slope (m).
The y-intercept is the point the line crosses the y-axis. This line crosses the y-axis of (0, 0). This makes the y-intercept equal to 0.
The slope is the rise of the line over the run of the line. Pick two points from the line. It doesn't matter which ones, you will get the right answer regardless.
I picked (0, 0) and (-3, 2). Subtract the x-values from each other, and subtract the y-values from each other.
-3 - 0 = -3 (x)
2 - 0 = 2 (y)
Divide the y by the x to find the slope.
2/-3 = -2/3
Plug in the slope and y-intercept into the equation.
y = mx + b
y = -2/3x + 0
y = -2/3x
Answer:
11 years approx
Step-by-step explanation:
Given data
P=$1000
A=2000
R=6.5%
T= ?
Calculate time, solve for t
t = ln(A/P) / r
substitute
t=ln(2000/1000)/0.065
t=ln(2)/0.065
t=0.693/0.065
t=10.66
Hence the time is 11 years approx
Answer:
1002
Step-by-step explanation:
171x6=1026
171×2=342
1026-342=684
684+318=1002
