Answer:
5.18 pounds per square inch
Complete question:
If the pressure is 6 pounds per square inch when the temperature is 440° F,find the pressure exerted when the temperature of the gas is 380°F.
Step-by-step explanation:
According to the Gay Lussac's Law:
where, P and T are the pressure and temperature of an enclosed ideal gas.
Given:
Initial pressure 
= 6 pounds per square inch
Initial Temperature 
=440° F
Final Temperature 
=380° F
Final Pressure 
=?
Substituting all values in the formula
= 
= 5.18pounds per square inch
Answer:
6236 students (to the nearest whole)
Step-by-step explanation:
The rule of 72 will have you divide 72 over the interest rate in percent form. Ignore the percent symbol
So we'll divide 72 over 8.47 to get...
72/8.47 = 8.50059
which is roughly 8.5 years for the money to double
If we round to the nearest whole number, then it takes 9 years for the money to double (according to the rule of 72). The year 1999 isn't listed so the next best choice is the year 2000. So I'm fairly confident the answer is C) 2000. Though your teacher may have 1998 in mind for some reason. If it were me, I'd go with 2000 because the year 1998 will have the account balance short of the goal of $10,000.
