To find the percentage of a number multiply it by whatever decimal you are using or a fraction that you have to convert into a decimal to find the percent. Example: What is 10% of 25? (.10)(25) = 2.5 so 10% of 25 is 2.5.
I'm not to sure about my work, since I got the wrong answer, then plugged in until they were equal. So, I'm not adding it so no one is confused by it. (because it isn't right)
y=3, x=4.
Answer: yes, it is
Step-by-step explanation:
A number is divisible by 6 if it is divisible by 2 and 3 simultaniously.
n = k(k+1)(k-1)
If k-1 is a multiple of 3, n is divisible by 3, so one of the requirements is ok.
Now, if k-1 is a multiple of 3, it can be even or odd.
if k-1 is even, then it is divisible by 2 and as it is divisible by 3 as well, n is divisible by 6
if k-1 is odd, then k and k+1 is even, hence, divisible by 2.
As n = k(k+1)(k-1), n is also divisible by 6.
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
The correct answer is {-5,11}
I hope this helps. :)
Have a great day.
