Answer:
$1.50
Step-by-step explanation:
1. we know that its $240 per 160 hot dogs
2. make that a ratio - 240:160
3. simplify the ratio so that the amount of hot dogs is at one (so divide both sides by 160)
4. so 240/160 = 1.5 . 160/160 = 1
5. 1.5:1
6. so for every one hotdog, you pay $1.50
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 %
500
because when you power to the second power a square root, it cancels and the answer is the number you originally had
The answer is 12/16... divide the fraction by 4 and you get 3/4
