The amount of heat needed to cook the pork roast is 1700 kJ.
The amount of heat absorbed by the roast is 14% of the heat produced = 14% X ?H = 310.38 kJ/mol
One mole of propane burns to produce 3 moles of CO2 and -2217 kJ of heat.
1700kJ/ (14% X ?H) = mol of C3H8 burned
1700kJ / (310.38 kJ/mol) = 5.48 mol C3H8
Since 3 moles of CO2 are produced:
3 X 5.48 mol= 16.43 mols of CO2
convert moles to grams:
16.43 mol CO2 X 44.0g/mol ~ 722.9 g CO2 produced
Velocity of the ring wraiths relative to the air:
The speed 
is what we want to find - this is the speed at which the wraiths are flying in the air.
(Note: 
denotes velocity, while 
denotes speed)
Velocity of air relative to the ground:
The ring wraiths want their trajectory to be due north, which means their velocity relative to the ground should be
To an observer on the ground, 
is the speed at which the wraiths would appear to be moving in the air.
The relative velocities satisify
The domain is another name for the values of x
In the points ( -5 , 0) , ( -4 , 2) , (0 , 10) , and (3 , 16)
-5, -4, 0, and 3 are the domains
Answer:
Okay I'm not thoroughly understanding your question. But here is my answer for BOTH ways.
Step-by-step explanation:
If it's 5 TIMES 3x/8 +2=7
x= 8/3 or x=2.6
If it's 5(3x) OVER 8 in fraction form +2=7
x= 11
Hope this answers your question.
Answer:
Nori would have 9/12 of a bag left.
Step-by-step explanation:
she had 2 2/12 and she used 1 5/12 so you subtract them and get 9/12
