PH can be calculated using the following equation
pH = -log [H₃O⁺]
for apple juice the hydronium /hydrogen ion concentration is 0.0003
pH = -log (0.0003)
pH = 3.5
correct answer is C
For ammonia
pH = -log (3.1 x 10⁻⁹)
pH = 8.5
answer should be 8.5
Answer: 6
Step-by-step explanation:
6 is the only number next to x and is multiplying with it (ex: 6x would be a coefficient but 6+x would not)

Answer:
To estimate the quotient, make the fractions "like" fractions. To do this, you need to make the fractions have the same denominator, and turn them into improper fractions.
Step-by-step explanation:
![27\frac{2}{3} = 27 \frac{20}{30}](https://tex.z-dn.net/?f=27%5Cfrac%7B2%7D%7B3%7D%20%3D%2027%20%5Cfrac%7B20%7D%7B30%7D)
![3\frac{9}{10} = 3\frac{27}{30}](https://tex.z-dn.net/?f=3%5Cfrac%7B9%7D%7B10%7D%20%3D%203%5Cfrac%7B27%7D%7B30%7D)
Now the denominators are the same --> they are "like" fractions.
![27\frac{20}{30} + 3\frac{27}{30} = ?](https://tex.z-dn.net/?f=27%5Cfrac%7B20%7D%7B30%7D%20%2B%203%5Cfrac%7B27%7D%7B30%7D%20%3D%20%3F)
![27\frac{20}{30} + 3\frac{27}{30} = (27 + 3) + (\frac{20}{30} + \frac{27}{30})](https://tex.z-dn.net/?f=27%5Cfrac%7B20%7D%7B30%7D%20%2B%203%5Cfrac%7B27%7D%7B30%7D%20%3D%20%2827%20%2B%203%29%20%2B%20%28%5Cfrac%7B20%7D%7B30%7D%20%2B%20%5Cfrac%7B27%7D%7B30%7D%29)
![27\frac{20}{30} + 3\frac{27}{30} = (30) + (\frac{47}{30})](https://tex.z-dn.net/?f=27%5Cfrac%7B20%7D%7B30%7D%20%2B%203%5Cfrac%7B27%7D%7B30%7D%20%3D%20%2830%29%20%2B%20%28%5Cfrac%7B47%7D%7B30%7D%29)
![27\frac{20}{30} + 3\frac{27}{30} = (30) + (1 \frac{17}{30})](https://tex.z-dn.net/?f=27%5Cfrac%7B20%7D%7B30%7D%20%2B%203%5Cfrac%7B27%7D%7B30%7D%20%3D%20%2830%29%20%2B%20%281%20%5Cfrac%7B17%7D%7B30%7D%29)
![27\frac{20}{30} + 3\frac{27}{30} = 31 \frac{17}{30}](https://tex.z-dn.net/?f=27%5Cfrac%7B20%7D%7B30%7D%20%2B%203%5Cfrac%7B27%7D%7B30%7D%20%3D%2031%20%5Cfrac%7B17%7D%7B30%7D)

Answer:
Option A, The pen cost less than $0.35.
Step-by-step explanation:
The given inequality is d ∠ 0.35
Now we have to define this inequality with the help of given options.
If d represents the cost of pen, then cost of pen should be less than 0.35.
Option A, The pen cost less than $0.35. is the answer.
