Answer:
4.732 grams
Step-by-step explanation:
2 US fluid ounces is exactly 59.147059125 mL of volume. 8% of that volume is 4.73176473 mL.
For a solution of this type, where 1 g/100 mL is considered a 1% solution this is the number of grams of solute needed.
About 4.732 grams of solute are needed to prepare 2 fl oz of 8% solution.
_____
We have assumed that 1 gram of solute gives you 1 gram of iodine. Depending on the exact solute used, that may or may not be the case.
Answer:
The dimensions are (7m-3) by (7m-3)
Step-by-step explanation:
We have the area of the rectangular field to be:
We need to factorize this expression.
Let us rewrite to obtain:
We can easily see that the expression is actually a perfect square trinomial.
This gives us:
Or
The limit (as 'x' approaches zero) of x²/(2x+1) is
0 / (0+1) = 0 .
You get this by substituting the limit in place of 'x'.
Sometimes that doesn't work. Sometimes it gives you
monstrosities like 0/0, or 1/0, or ∞/∞ .
But it works for this one. There's nothing wrong with 0/1 = zero .
R= 5
(2-6). -4
—— = ——-
(4-r). (This has to be -1 for the answer to be 4)
4-5=-1
So r=5
