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
8.2y that the cayse 45 is 7 byt 8.2
Let Us Call <span>better</span>
translate 5 hours and 15 min into all min to find the total for us cell u. 5*60=300, so 315 minutes. So then multiply .15 by 315 and you get 47.25$.
<span>Now do Call for us. so first multiply 5 by 10.50. you get 52.50$.</span>
