A recipe calls for 2 cups of milk for every 6 1/4 cups of flour. If you increase the flour to 43 3/4 cups, how many cups of milk

balu736 [363]

First you must convert 1/4 to a decimal which is 0.25 then multiply that by 6= 1.5, so for every 1.5 cup of flour, you add 2 cups of milk basically.
If you increase the flower to 43 3/4, you need to again, turn 3/4 into a decimal which is 0.75 and multiply 0.75 by 43 = 32.25, then 32.25 divided by 1.5 = 21.5

CONCLUSION: You will use 21.5 cups of milk!
Hope this helped:))

Answer:

The electron moved down to an energy level and has an energy of

$10.92 \times 10^{-19} \textsf{J}$

Step-by-step explanation:

$\textsf{initial energy level of electron}= 16.32 \times 10^{-19} \textsf{J}$

$\triangle E =\textsf{energy released}= 5.4 \times 10^{-19} \textsf{J}$

A positive energy change means that the electron absorbs energy, while a negative energy change implies a release of energy from the electron.

Therefore, when an electron absorbs energy, the electron moves up to higher energy levels, and when an electron releases energy, it moves to lower energy levels.

$\triangle E=E_2-E_1$
