Answer:
method I = 88 chairs
method II = 62 chairs
Explanation:
This problem can be modeled by a system of two linear equations.
Define x as the number of chairs refinished by method I and y by method II
The sum of hours spent on both methods should equal 199 and the sum of total material cost should equal $1226, therefore:
Multiplying the first equation by -18 and adding it to the second equation we can solve for the value of y:
We can now apply the value of y found to the first equation and solve for x:
Therefore, they should refinish 88 chairs with method I and 62 chairs with method II
Answer:
700 mL or 0.0007 m³
Explanation:
P₁ = Initial pressure = 2 atm
V₁ = Initial volume = 350 mL
P₂ = Final pressure = 1 atm
V₂ = Final volume
Here the temperature remains constant. So, Boyle's law can be applied here.
P₁V₁ = P₂V₂
So, volume of this sample of gas at standard atmospheric pressure would be 700 mL or 0.0007 m³
