Answer:
23 2/5
Step-by-step explanation:
convert mixed numbers to improper fractions: 1 3/10=13/10
13/10*18
convert element to fraction: 18=18/1
=18/1*13/10
cross cancel common factor:2
=13/5*9/1
multiply fractions
=13*9/5*1
=117/5
convert improper fraction to mixed numbers
23 2/5
Answer:
The answer to the question is
The ratio of the two gas pressures
, that is Px to Py = 1/6
Step-by-step explanation:
Let the gases Volumes be V₁ and V₂
Where volume of X = V₁ and
volume of Y = V₂
The volume of Y is half the volume of X
∴ V₂ =
× V₁
Let the number of moles be n₁ and n₂ in X and Y respectively
therefore n₂ = 3 × n₁
The pressure of the gas in X is Pₓ and the pressure of the gas in Y is
then we have
P₁ × V₁ = n₁ × R × T₁ , and P₂ × V₂ = n₂ × R × T₂
(P₁ × V₁)/(n₁ × T₁) = (P₂ × V₂)/(n₂ × T₂)
but T₁ = T₂
Therefore
(P₁ × V₁)/n₁ = (P₂ × V₂)/n₂. However n₂ = 3 × n₁ and V₂ =
× V₁ therefore substituting in the equation we have
(P₁ × V₁)/n₁ = (P₂ ×
× V₁ )/(3 × n₁) from where
P₁ /P₂ = (
× V₁ × n₁)/(V₁×3 × n₁) =0.5/3 = 1/6
The ratio of
= 1/6
First replace x with -2 in the g(x) equation and solve:
G(x) = x + 4 = -2 + 4 = 2
Now replace x in the f(x) equation with the solution of g(x).
F(x) = 1-3(2) = 1-6 = -5
Fg(-2) = -5
