Answer:

Step-by-step explanation:
As we can see the given expression as three complex parts and all are being multiplied.
Lets simplify each part separately and then multiply all of them in the end
Part1
 
  
Cancelling 8 in numerator with 8 in denominator



Part2

simpliying



Part3
Third part is  , and it does not need to be further simplified
, and it does not need to be further simplified
Now multiplying all the three parts





So our final answer is 
 
        
             
        
        
        
We see that the second definition is not a good definition. We want both parts to have the same truth value, but we see that we can have two angles created by a ray that are not equal. That means the antecedent is false but the consequence is true, which means it's not an iff statement, and a bad definition in this context.
 
        
             
        
        
        
44 fl oz there are 2000 pounds in a tone for x amount of supplement… ( supplement volume)/(weight in pounds) = x/(5.5*2000)=1/250 multiplied by 11000
x=11000/250=44 fl
