His pay is D - $690, because 40x15=600 and then you add 3 hours of double pay (30x3=90), so 600+90=690
Okay.. so I guess this is how it goes:
1. Rainforest
2. Temperate deciduous
3. Marine
4. Taiga
5. Tundra
Pls don't completely rely on it, this is my best guess and it's probably right except with Marine life and temperature deciduous. 70% I feel like it would temperate then marine. But check with urself again. Hope this helped..
Answer:
LiOH
Explanation:
Just by looking at the answer choices, you can tell which one is the odd one out.
LiOH is the only choice with a OH- attached to it. By the Arrhenius base definition, bases have OH- groups attached to them.
In contrast, by the Arrhenius acid definition, acids have H+ protons attached to them. As we can see from the other three answer choices, they all have an H: HCl, HF, HBr.
Thus, the answer is LiOH.
Hope this helps!
