A truncated cone 2007-03-10
From Russell:
Hello, I have attempted to use two of your answers already given and had no real success. This young lady is making a cat food dispenser using a truncated cone. The top of the cone as a diameter of 5 inches with a height of 6 1/2 inches and diameter of 3 inches for the bottom.

Could you please map out a solution for the both of us to understand? Thank you so much for your time and for this wonderful service.

Les quantités d'aliments 2002-03-09
From Benhacine:
soient les aliments A1, A2, A3.....An contenant respectivement le nutriment "a" aux quantités a1, a2, a3, et an sachant qu'un organisme a besoin d'une quantité connue de nutriment "a" égale à "Be",

Ayant: A1.a1 + A2.a2 +.....+ An.an = 100.Be


A1 + A2 + A3 +....+ An = 100

Quelles seront les quantités d'aliments A1, A2, et An qui satisferont le besoin défini "Be" de l'organisme?
