Answer:
The amount of salt required is 0.3685 grams.
Step-by-step explanation:
20.9% of 1 gram of salt is chlorine, which means the grams of chlorine in 1 gram of salt are

Now, to make 220 ppm solution, it must be that

where
is the grams of chlorine required.
We rearrange the equation and solve for 





since 1 gram of salt has 0.209 grams of chlorine, 0.07702g of chlorine corresponds to

Thus the amount of salt required is 0.3685 grams.
Answer:
C
Step-by-step explanation:
The amount Adam invested in a six years CD was $12,000 was 7.1%
Adam made a withdrawal of $2500 early. The early withdrawal was worth eighteen months of interest on the amount withdrawn.
Monthly interest = 7.1% / 12
= 0.59%
The interest for 18 months will be
(7.1% /12)18
= 10.65%
The penalty for withdrawing early was 18 months worth the interest on the amount withdrawn
= 2500 * 10.65%
= 266.25
This means Adam needs to pay a penalty of $266.25 for withdrawing early
1/3 of 24 tickets is 8. I got this answer by dividing 24 by 1/3, and got the exact answer of 8!!!! Hope this helps!!!
Answer:
7.2326
Step-by-step explanation:

Multiply both sides by 3, because 3 is our denominator (bottom number in a fraction), and we want to get rid of the denominator.
3 × (v + 9) = 8 × 3
Simplify.
3v + 27 = 24
Then, subtract both sides by 27.
3v = 24 - 27
Simplify.
3v = -3
Divide both sides by 3.
v = -1
