Answer:
Therefore the volume of the gas is 32 cubic feet.
Step-by-step explanation:
Given that,
The volume of a gas varies directly with its temperature and inversely with the pressure.
V= Volume of the gas at constant mass
T= Temperature at constant mass
P= pressure at constant mass
.
Given that,
At constant mass, the volume of a certain gas is 15 cubic feet and a pressure of 40 pound per square inch at a temperature 300 k.
=15 cubic feet, 
=40 pound per square inch and 
= 300 K
, 
=20 pound per square inch and 
= 320k
.
Plugging all values
cubic feet
Therefore the volume of the gas is 32 cubic feet.

Answer:
(a) SSS
Step-by-step explanation:
Two of the sides are marked congruent, and the third side is shared (so is congruent to itself). The triangles are congruent by the Side-Side-Side (SSS) postulate.
Answer:
5.45 mph
4.54 mph
Step-by-step explanation:
8 ft/sec * 60 seconds/minute = 480 ft/minute
480 ft/minute * 60 minutes/hour = 28,800 ft/hr
28,800 ft/hr / 5280 ft/mil
20 ft/3 sec = 6.67 ft/sec
6.67 ft/sec * 60 seconds/minute = 400.2 ft/minute
400.2 ft/minute * 60 minutes/hour = 24,012 ft/hr
24,012 ft/hr / 5280 ft/mil = 4.54 mph
