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:
Parallel lines will have the same slope, so m=3. The point (0, 2) is on the y-axis so it can be used as the y-intercept of the line; b=2. This gives rise to the equation: y= 3x + 2
Step-by-step explanation:
You can build a cylinder in two ways: either you draw a circle on a plane, and "raise" it perpendicularly to the plane itself, or you start with a rectangle, and rotate it around one of its sides.
For these reasons, if you cut the cylinder with a plane parallel to the base you have a circular cross section, while if you cut the cylinder with a plane perpendicular to the base you have a rectangular cross section.

Answer:
Step-by-step explanation:
If B lies between A and C on a line segment, then ...
AB +BC = AC
(2x -17) +(x +1) = 14
3x = 30 . . . . . . . . . . . . . add 16, collect terms
x = 10 . . . . . . . . . . . divide by 3
AB = 2(10)-17 = 3
BC = 10+1 = 11
