Answer:
2 or 12
Step-by-step explanation:
The answer that we will use this equation 1/t1 +1/t2=1/ttotal
where t1 is the time of smaller pipe while t2 is the of the larger pipe
Given t total =4 while t2 is equal to t2=t1-6
So know you can solve the problem by changing it into (2t1-6)/(t1*(t1-6))=1/4
8( t1-3)=(t1^2-6t1)
t1^2-14t1+24=0
t1=2 or 12
Answer:
3/10
Step-by-step explanation:
An hour is 60 mins
so the fraction would be 18/60
Then you can divide both numbers by 6 to 3/10
Answer:
if the x is for multiplication this is a false statement the true answer would be5/8 if the x is a variable then x would =11.304
