Answer:
the simpelist awncer is we are all guna die
Step-by-step explanation:
Differentiating both sides of PV = C with respect to t gives us ...
... P'V +PV' = 0
Filling in the given numbers gives us ...
... (40 kPa/min)(900 cm³) + V'(150 kPa) = 0
Solving for V' gives ...
... V' = -(40 kPa/min)(900 cm³)/(150 kPa)
.. V' = -240 cm³/min
The volume is decreasing at the rate of 240 cm³/min.
Kalon + Marna = 12/7 hours working together
( I attached two formulas. Use formula 3)
Worker 2 Time = (worker 1 Time) * Total Time / [(worker 1 Time) - Total Time]
Worker 2 Time = ((4) * 12/7) / [4 - 12/7]
Worker 2 Time =

So the two negatives make a positive, I dont think it’s a problem with too much work 3-(-2)=3+2 that’s basically it
