Well the only reason why I put #1 as D. was because I saw sodium acetate under examples of supersaturated solutions in my Chem book. And #3 I was sort of just guessing on.
But I see now that 1 is C. and 3 is D. So I got it!
Homework Statement
Match the items to the statements below.
A Dilute
B Unsaturated
C Saturated
D Supersaturated

How can I go about finding the exact values of tan 510, sin (-315) and sin 750? I'm unsure of where to even begin on these problems and any help would be greatly appreciated.
Never mind, I found the answers to these problems. However, there is another problem on my homework the reads: "Find...
On my homework is says "On the Beaufort scale of wind force, the term "fresh gale" describes wind speeds from 39 mi/hr to 46 mi/hr. Write a compund inequality to describe "fresh gale" wind speeds."
Would an acceptable inequality be {S: 39 < S < 46} ?
