Answer: it’s C
Step-by-step explanation: because my teacher told me
We know that:
The markup is the price added to the cost price of goods...
To find the markup, we must multiply the percent increase by the original price (before markup).
So:
10,000 x 5% (or 0.05) = ?
10,000 (You do not have to follow my way of multiplying, do what is comfortable for u)
x 5 (Ignore the decimals then we move it after we get the answer)
----------
50,000 move the decimal back 2 places so it is 500
The final answer is:
The markup amount is $500...
<span>Answer:
MgF2 ====⇒ Mg+2 + 2F-
Ksp = [Mg+2][F-]^2
Let S = molar solubility of MgF2
[Mg+2] = S ; [F-] = 2s
Since the [F-] is initially 0.40 M, then [F-] = 0.40 + 2S
6.4 x 10^-9 = (S) (0.40 + 2S)^2 ; one can neglect the 2S in the 0.40 + 2S expression since it is very, very small compared to the 0.40 already present.
6.4 x 10^-9 = S(0.40)^2
S = 4.0 x 10^-8
Molar solubility = 4.0 x 10^-8</span>
Answer:
-0.048
Step-by-step explanation:
-1.2 * 0.04 = -1.2 * 4 / 100 = -4.8 / 100 = -).048
