AI Thread Summary
To create an orange dye, a mixture of 3 parts red and 2 parts yellow is used, while a green dye consists of 2 parts blue and 1 part yellow. When equal amounts of green and orange dyes are combined, the resulting proportion of yellow dye is calculated to be 11/30. The initial claim of 3/8 as the proportion of yellow dye is incorrect. The explanation provided in the linked resource is accurate and clarifies the reasoning behind the correct answer. Understanding the proportions in dye mixtures is essential for achieving the desired color outcomes.

To make an orange dye, 3 parts of red dye are mixed with 2 parts of yellow dye. To make a green dye, 2 parts of blue dye are mixed with 1 part of yellow dye. If equal amounts of green and orange are mixed, what is the proportion of yellow dye in the new mixture?

This is not a homework question btw. My answer is 3/8. Yet the correct answer is 11/30. Can anyone explain why?

I don't agree with the explanation here:

lol why would you not agree with it? it's correct and good reasoning.
 
haha. i get it now. thx.
 

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
