Answer:
300
Step-by-step explanation:
The volume of the gas varies inversely as the pressure
V= k/p
K= VP
= 1200×200
= 240,000
Therefore the volume when the pressure is 800
K= VP
240000= V×800
V= 240000/800
= 300
Hence the volume is 300 cubic centimeters

Answer:
x<-4 or x≤4
Step-by-step explanation:
The surface area of a sphere is A = 4π R²
The volume of a sphere is V = (4/3) ( π) (R³)
The ratio of (surface area) to (volume) is
4 π R² / (4/3) (π) (R³)
Divide top and bottom by 4π : R² / (1/3) (R³)
Multiply top and bottom by 3: 3 R² / R³
Divide top and bottom by R² : 3 / R .
For the Earth,
A / V = (3) / (3,960 miles) =<em> 0.00076 per mile </em>(rounded)
