Answer:
16 bags
Step-by-step explanation:
To find this, we <em>divide 2 over 1/8</em>, to see how many <em>units of 1/8 fits into that of 2</em>.
can be rewritten as <em>2*8</em>. 2*8 = 16 bags.
Answer:
-2/3
Step-by-step explanation:
The slope of a line is found by
m= (y2-y1)/(x2-x1)
= (12-2)/(-10 -5)
= 10/-15
= -2/3
Answer:
- 33 1/3 liters of 30%
- 16 2/3 liters of 45%
Step-by-step explanation:
Let x represent the liters of 45% solution needed. Then the amount of HCl in the mix is ...
0.45x +0.30(50 -x) = 0.35(50)
0.15x = 0.05(50) . . . . . simplify, subtract 0.30(50)
x = (0.05/0.15)(50) = 50/3 = 16 2/3 . . . liters of 45% HCl
33 1/3 liters of 30% and 16 2/3 liters of 45% HCl are needed.

<em>Comment on the solution</em>
You may notice that the general solution to a mixture problem of this sort is that the fraction of the mix that is the highest contributor is ...
(mix % - low %) / (high % - low %) = (.35 -.30) / (.45 -.30) = .05/.15 = 1/3
Answer: 1/2
Step-by-step explanation: 1/3 + 1/6
1- multiply 1/3 by 2
2- 2/3 + 1/6= 3/6
3- reduce to 1/2
