Math Wizards - Help!
Edited on Thu May-05-11 09:36 PM by bluesbassman
Unfortunately I spent most of my HS geometry classes out on smoker's corner. If I can simplify this for my daughter I will be a hero! Any tips?

a=1/2(92√3)(92)

1. 7330
92 x 92 = 8464
square root of 3 = 1.73205080756888
1.73205080756888 x 8464 = 14660.078035263
14660.078035263 x 1/2 (or divided by 2) = 7330.0390176315

5. That's what I got, but...
I'm just a bass player.

2. A little hard to do ... it all depends upon how one interprets
Edited on Thu May-05-11 10:42 PM by chemenger
the way you typed it in.

One interpretation would be:

a = 1/2 (ie. one half) times (92 times the square root of 3 times 92) or a = * 92 * √3 * 92
a = 46 times 1.372 times 92
a = 79.675 times 92
a = 7330

A second interpretation would be:

a = 1 divided by (2 times 92 times the square root of 3 times 92) or
a = 1 (2 * 92 * 1.372 * 92)
a = 1 divided by (184 times 1.372 times 92)
a = 1 divided by (318.7 times 92)
a = 1 divided by 29320
a = 0.00003412

Note than since 92 is a multiplier in the equation twice it can be written as 92^2 (ie 92 squared).

On edit: if you type your equation into EXCEL exactly as typed here, ie: 1/2 * (92 * 3^2) * 92 you get 38088.

So ... take your pick.

4. Small nit: that "3^2" should be "3^0.5"
Excel does get it right - 7330...

Very good point
I didn't even consider that it might be 1 over (all the rest).

Wonder what the original actually looked like?

9. She was working on calculating areas for various triangles and quadrilaterals
Edited on Fri May-06-11 12:33 AM by bluesbassman
stuck to each side of a hexagon.

It was: a= one half times (92√3)(92)

3. Thanks to both of you!
She and I walked through both of your solutions and it helped her a lot.

Knew I could "count" on The Lounge! :rofl: :applause:

7. Well, I never engaged in this kind of thing before...
But yes, I think it can be very easily done. We'll just put some bleachers out in the sun, and have it on Highway 61. :)
