You need to prepare a 30ml solution of a 1: 6 syrup solution. you have on hand a 50% syrup solution, and a 1: 200 soda solution. how many ml of each solution do you need to create this final solution?

a = 5 ml of 50% syrup solution will be used

Explanation:

Let us suppose the 50% of the solution being used as "a"

(30 - a)  then will be the amount of 1/200 solution used and the equation will be as follows,  

0.5a +0.05(30 -a) = 1/8 (30)

0.5a + 1.5 -0.05a= 3.75

0.45a = 2.25

a = 5 ml

as for the sky, according to nasa:

"sunlight reaches earth's atmosphere and is scattered in all directions by all the gases and particles in the air. blue light is scattered more than the other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time."
