(PV=nrt) Divide nr from both sides to get t by itself. t=PV/nr
Answer:
A - PV/RT = n
Step-by-step explanation:
The objective is to isolate the variable n which represents moles. To do so, you must get rid of the surrounding variables.
Surrounding n, the variables R (gas constant) and T (temperature) are shown being multiplied with n. To get rid of them, you must do the inverse which is to divide.
PV = nRT
Divide both sides by R
PV/R =nT
Divide both sides by T
PV/RT = n
And now, the variable n has been isolated and the new equation to solve for moles is presented.

If the price of one ticket of bus is $180 and the bus has 56 seats then the maximum revenue that it can earn is $5107.6
Given that the price of a bus ticket to Saskatoon is $180 and the bus has 56 seats.
We are required to find the maximum revenue that the bus company can earn.
Suppose x represents the number of seats, y represents the total amount.
Price=$156
Seats=56
When the bus is of half capacity the bus seats will be 28.
As price decreases th rider gains 2 more.
Revenue equation.
y=(156.5x)(28+2x)-------------1
Expanding the equation.
y=4368-140x+312-10
Differentiating with respect to x.
dy/dx=0-140+312-20x
=172-20x
Put dy/dx=0
172-20x=0
x=8.6
Substitute the value of variable x in the equation 1.
y=(156-5x)(28+2x)
=$5107.6
Hence the maximum revenue that the bus company can earn is $5107.6.

Answer:
False
Step-by-step explanation:
Definition of Tangency : Tangent to a circle is a line that touches the circle at one point, which is known as Tangency.
At the point of Tangency, Tangent to a circle is always perpendicular to the radius.
We are supposed to find The point of tangency of line S to circle A is M
Considering the definition,
The lines S touches the circle at point J not at M
So,The point of tangency of line S to circle A is M is False
So, Option B is correct
Hence The point of tangency of line S to circle A is M is False
Answer:
just the positives I think
