[pianotech] OT: are you smarter than an 8th grader?

[Paul T Williams]

You guys are awesome! I didn't really expect much of a response, but then 
again, some of you really get into your math!  I should have reworded this 
as: If let off on a Steinway M is 1/14th" and key dip is 7/8th of specs, 
how should I compensate aftertouch and/or blow distance to please a heavy 
handed pianists! LOL

thanks guys! you rock!

Paul

That's the answer I got as well.

My starting equation was:

1/3X + 1/4X + 8 = X  (where X is the total length of the bolt)

Paul,

I believe Bruce got it.  Here's why:


Find the common denominator, in this case, twelfths.

So you now have 4/12th and 3/12 respectively of black, totaling 7/12 of 
the cloth in black.  That leaves 5/12th of gray.  5/12 = 8yds, so 1/12 = 
8/5 (or 1.6 yds).  So if 1/12 is 1.6yds, 12/12 or 1 (the whole thing) is 
12 * 1.6 = 19.2 yds.

here it is am I'm having a brain fart: 

A bolt of cloth is colored as follows: 1/3 and 1/4th of it are black, and 
the remaining 8 yards are gray. How long is the bolt of cloth? 

Some of you can do this in a heartbeat, but I'm forgetting my simple 
algebra. 

Thanks 
Paul 
 Ps: the answer is not how much to order for a bench cover!
