9 has blockage too, at the end.

All have blockage somewhere except 5.

Common core tax plan?

[layman]

It’s #5 .... trust me.

The answer is the angle of the wake of the boat.

I just mentioned that to Paul, my second and last husband, and he remembered another U of Chicago PhD question.

How many piano tuners are in Chicago?

It required you to make the right assumptions. The numbers were just based on the assumptions you made. How many people? How many have pianos? How many get their pianos tuned? How many piano tuners would that support?

So you might want a U of C person as part of your bridge design team, but you’d be best off to add a PhD from MIT to actually build the thing.

5 all others are blocked.

Pipe is blocked just before 9

[FreedomPoster]

9 is blocked at the very end. I missed that, too.

[Boiler Plate]

Seriously? This has people confused? Just find the lowest pipe that’s not blocked.

[Boiler Plate]

The only one not blocked is 5

[virgil]

9 ;has a blockage too

[mac_truck]

Is it #4?

That would be my answer.

[Boiler Plate]

Simple is good.

7

Depends on what the definition of cup is. It’s the space between 4 and 9.

That pot will be out of coffee before #5 is filled.

What Democrat scandal is getting ‘dumped’ while we are all wondering about some coffee cup getting full? Shiny object, shiny object.

It is not only plumbers. When I moved in September, the Comcast installer was working on getting my cable and internet connected. I walked into the living room to see a very large crack staring back at me. I wasn’t sure if it was the San Andreas Fault, the Continental Divide, the Grand Canyon or something much farther away because I was very close to seeing (his) Uranus.
