Answer:
We know that the formula to mix chemical solutions is: C1V1 = C2V2
where C represents the concentration of the solute, and V represents volume in milliliters or ml.
In this case, we have:
0.06V1 = 0.15×350
Solving for 'V1' we have:
V1 = (0.15×350)/0.06 = 52.5/0.06 = 875
Therefre I can make 875 mL of a 6% solution by diluting 350 mL of a 15% solution.
This is the answer if you have any questions feel free to ask also could you check my question I need help ASAP!
Answer:
b - 60
Step-by-step explanation:
Let the number of books in the library be b.
The number of books in the library minus the 60 checked out is translated into a variable expression as b - 60
They must sell 28 candles in order to gain more than $125 profit.
$125/$4.50 = 27.77 (round it up) = 28.
28 x $4.50 = $126
As long it’s over 28 candles, you’ll make more profit than $125.
