Answer:
40 drops
Approximately 0.166 %
Step-by-step explanation:
It would be easier to work the same units for volume
Since there are 1000 ml in a liter
Original water volume 1.2 L = 1.2 x 1000 = 1200 mLl
The final volume of the acid-water solution = 1.202 L = 1202 mL
So total volume of acid added = 1202-1200 = 2 mL
Each drop of acid is 0.05 mL
Number of drops added = 2/.05 = 40 drops
Percent of acid in acid solution = (Volume of acid added)/(Final volume) x 100 = (2/1202) ≈ 0.00166 x 100 ≈ 0.166 %
60*115/100=69
Retail price is 69
Answer:
The absolute value of -433 is 433.
Step-by-step explanation:
Remember, the absolute value of a number is its distance from zero. The distance from -433 to 0 is 433.
The correct answer for this question would be the last option. The complete factor of 25x^2 – 36 is <span>(5x – 6)(5x + 6). To check, multiply both values. 5x times 5x is 25x^2, and -6 times 6 is -36. Which gives us 25x^2-36. Hope this answers your question. Let me know if you need more help next time.</span>
