Answer:
350 mL
Step-by-step explanation:
Let q represent the quantity (in mL) needed of the 70% solution. Then the total amount of mixture will be q+50 milliliters. The total amount of alcohol in the mixture will be ...
0.70q +0.30(50) = 0.65(50 +q)
.05q = 17.5 . . . . . . subtract (0.65q +1.50)
q = 350 . . . . . . . . . divide by 0.05
You will need 350 mL of the 70% solution.
Step-by-step explanation:
19 -12+6k=14+7k
7+6k=14+7k
-6k -6k
7=14+x
-14 -14

Copper
Explanation:
Copper would be beacuse it's non-toxic, it's antimicrobial, it's rustproof, and it is affordable.
Number of spaces would be number of squares - 1
You would have 12 squares and 11 spaces.
Multiply number of each by their size then add the two together:
12 x 7 1/4 = 87 inches
11 x 3 5/16 = 36 7/16 inches
Total = 87 + 36 7/16 = 123 7/16 inches
Answer: 123 7/16 inches
Answer:
