Answer:
The answer is 1.
Step-by-step explanation:
Nobel gases have full shell of valence electrons, that is why they tend to not enter any chemical reactions because they are satisfied while metals have very few electrons in the valence shell, so they are active in any chemical reaction.
Answer:
9 to 7 = 45 to 35..
Step-by-step explanation:
Given function:
<u><em>to find x:</em></u>
- divide 45 by 9
- if 9·5=45 then x would be 7·5..
·
Therefore, x=35.
Answer:
y = 8.9
Step-by-step explanation:
8^2 + y^2 = 12^2
64 + y^2 = 144
subtract 64 from both sides
y^2 = 80
square root both sides
y = square root 80
y = 8.9
In symbols, sqrt(648) = 2^a * 3^b.
One way in which to tackle this is to factor *648.
648 = 81*8.
Note that 81 = 3^4 and that 8 = 2^3.
Therefore, a = 4 and b = 3.
The answer to this is -9 < x < -19
