Answer:
Step-by-step explanation:
A Hamiltonian circuit uses each vertex once and only once. (may repeat edges)
An Euler circuit uses each edge once and only once. (may repeat vertices)
That is to take the number rounded to the nearest value to two numbers to the right of the decimal:
5.62

Answer:
351
Step-by-step explanation:
27C2 = 27! / 2! × (27-2)!
= 27×26×25! / 2×1 × 25!
= 27×26 /2
= 27×13
= 351
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 %
