Answer:
(L, W) ≈ (8.33, 4.17)
Step-by-step explanation:
Substituting for L, we have ...
2(2W) +2W = 25
6W = 25
W = 25/6 ≈ 4.17
L = 25/3 ≈ 8.33
The rounded "exact" solution is ...
(L, W) = (8.33, 4.17)
When you divide you always do the reciprocal of the second number You would (x/1) times (1/9x)
Once you do the reciprocal it turns into multiplication
Step-by-step explanation:
"If the sum of 2 angles is 180°, then each is the supplementary angle of the other".
None of the given choices is the correct solution.
The setup of the problem is a correct, if somewhat weird, description
of the ideal gas laws, but the temperature involved in the law is the
ABSOLUTE temperature, NOT the Celsius or Fahrenheit one, or
any other scale where 'zero' is not 'Absolute Zero'.
Zero Celsius is (about) 273 Celsius-size degrees above Absolute Zero.
So the original temperature of the gas is (273 + 2.5) = 275.5 Kelvins
(Celsius degrees above absolute zero). THAT's the temperature that's
going to change in inverse proportion to the volume.
(if the pressure doesn't change)
The volume has been multiplied by 100cm³/500cm³ = 1/5 .
Since the temperature changes inversely, it will be multiplied by 5 .
Final absolute temperature = (5) x (original absolute temperature) =
(5) x (275.5 K) =
1377.5 K .
The final Celsius temperature is (1377.5 - 273) = <em>1104.5 °C</em>.
"But those are the choices in the assignment !"
Then the person who wrote the question in the assignment is wrong.
None of the choices they gave is correct.
Answer:
A. I believe I hope its correct I'm sorry if its wrong:( I tried.
