Which is a homogeneous mixture? A air B pizza C jar of mixed nuts D salad dressing

A) Air

Explanation:

A homogenous mixture is one that has uniform composition throughout. Air is comprised of several types of molecules (oxygen, carbon, nitrogen...). If you take a chunk of air, you will get the same ratio of those molecules if you take a different chunk of it. They will be made of the exact same things no matter where you take your sample.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
