Answer: i can see if i can what is the problem

Answer with Explanation:
The acidity of an aqueous solution is a term used to identify how acidic the solution is. An acidic solution is a solution in which the concentration of hydrogen ions is greater than the concentration of hydroxide ions. In the other case around if the concentration of hydrogen ions is lesser than the concentration of hydroxide ions the solution is termed to be basic or alkaline. For a solution with equal concentration of hydrogen and hydroxide ions the solution is termed to be neutral.
The acidity of solutions is compared on the basis of the concentration of the hydrogen ions reduced to log of base 10 to ease calculations. The comparison is made in terms of 'pH' value which is defined as
![pH=-log[H^+]](https://tex.z-dn.net/?f=pH%3D-log%5BH%5E%2B%5D)
where
is the hydrogen ion concentration of the solution in moles per liter of solution.
If the pH is < 7 the solution is acidic and the closer the pH value to 1 the higher is the acidity of the solution.
Answer:
- 3/5" = 12'
- 1 3/4" = 35'
- 1 1/4" = 25'
- 9/10" = 18'
- 2 13/20" = 53'
Explanation:
One number is wrong; they all lack units.
The basic ratio is 1" = 20', so you can divide feet by 20 to find inches.
- 3/5" = 12'
- 1 3/4" = 35'
- 1 1/4" = 25'
- 9/10" = 18'
- 2 13/20" = 53'
Perhaps you want decimal inches:
- 0.60" = 12'
- 1.75" = 35'
- 1.25" = 25'
- 0.90" = 18'
- 2.65" = 53'
Answer:
def main ():
sentence = input("Please enter a sentence:")
print("Original Sentence:",sentence)
# start at the third character
for i in range(2, len(sentence), 3):
# access the string by index
print("Every third letter:", sentence[i])
Explanation:
def helps define the sentence ( input)
in order to start printing from third letter we start the range from 2 and keep the step 3 . The range i is in square parenthesis to show the range and access string.
