Answer:
V₂ = 450 cm³
Step-by-step explanation:
The volume of a gas V held at a constant temperature in a closed container varies inversely with its pressure P.

If V₁ = 600 cm³, P₁ = 300 mm hg, P₂ = 400 mm hg
We need to find a new volume. Using the above concept,

So, when the pressure is 400 mm hg, its volume is 450 cubic centimeters
Option 2:
is the right answer
Step-by-step explanation:
We have to convert the details given in Plan one to an equation
Let x be the number of visits to the gym
and y be the total cost for plan one
So,
As each visit costs $3, x number of visits will cost 3x
One time fee is $50
So the equation can be written as:

Hence

List of the first few prime numbers greater than 3:
5, 7, 11, 13, 17, 19, 23, 29
Now find the combination that you can multiply and still have a 2 digit number:
5 x 7 = 35
5 x 11 = 55
5 x 13 = 65
5 x 17 = 85
5 x 19 = 95
5 x 23 = 115 ( 3 digit number, can't use).
7 x 5 = 35
7 x 11 = 77
7 x 13 = 91
7 x 19 = 133 ( 3 digit number, can't use).
The largest 2 digit number would be 5 x 19 = 95
I can’t see the top of the image. Can you make it more upper a little? I think it is 9
