It's pretty easy lol.
Take 98-8 that gives you 90. (Thickness of the shelves are 8 inches)
You have 9 actual open shelves between the top and bottom
90/9=10
Yeah, it is. But I think the assignment, or w/e that Shaft had to do, was to work that equation, JUST using variables.
From the equztion he posted a bit earlier, it looks like all the variables have to be in terms of length.
Was all too long ago for me. The answer in
numbers, is obviously 10 inches, but I don't think that's what they were looking for.
I think, that this is the same problem, and what the assignment was....

Solve (L) kL(T T0) for T. (L) kL(T T0). Note: Treat (L) as one variable. (L) kLT kLT0 Remove parentheses. (L) kLT0 kLT Add kLT0 to both sides.
Divide both sides by kL.
Can you show that is an equivalent solution? ■ T = (^L) kL + T0
(^L) + kLT0 kL
= T
can someone do this
for me
in english plz
/e It looks like the assignment was ...NOT to get the answer 10 inches, but to be able to work the equation, "without" putting the actual numbers in first.
/ee Not sure, but it also looks like in may involve "set theory" as well, or maybe "functions".

A set of eight built-in bookshelves is to be constructed in a room. The floor-to-ceiling clearance is 8 ft 2 in. Each shelf is 1 in. thick. An equal space is to be left between shelves. What space should there be between each shelf and the next? (There is no shelf against the ceiling and no shelf on the floor.
I think the (^L) is supposed to be the upside down U symbol, which I think stands for
intersection of sets, followed by an L.
