Answer:
The new volume is
.
Step-by-step explanation:
We are given with the volume of a gas varies inversely as the pressure upon it.
Initial volume is 160 cubic centimetres and initial pressure is 108 Pa. It is required to find the volume when the pressure is 87 centimetres.
According to given condition,


is new volume

So, the new volume is
.
Answer:
26.4
Step-by-step explanation:
<u>Law Of Cosines:</u>

This should work for any side. This can generally be thought as:

If this is too confusing here's the formula for the other sides (which is essentially the same, just different variables)


Anyways now just plug in the known values into the equation

Square and multiply values

Add the values in the numerator

Take the inverse of cosine on both sides

calculate arccosine (inverse cosine) using a calculator

Round to nearest tenth

Answer:
1) x=1/2-y/2-3z
2)x= 16/3- 2y/3- 5z/3
3)x= 11/7- 3y/7+ 4z/7
Step-by-step explanation:
isolate the variable, to do that divide each side by the factors that don't contain the variable
