Answer:
Option D is correct. A pound sign is used to indicates that a cell is not wide enough to display its numbers.
Explanation:
A pound sign symbol indicates that a cell is not wide enough to display its number in Excel. However, it is noted that if you use or installed a US keyboard in your computer then hash symbol (#) is shown and the pound sign symbol is shown if you use or installed the UK keyboard layout in your computer.
Why other options are not correct.
this symbol is used for multiplication in formula or in a cell to multiply the numbers with each other.
A dollar sign is used in a cell to show the currency. If you want to show the cell value as a currency. Then, you can use the dollar sign.
Percentage sign in the cell shows that value in a cell is representing a percentage of some values.
Maybe it's because he hasn't set up the new system once he does that then he should be able to function it but if he is still having trouble then he could call the company or ask for refund
Answer:
The solution code is written in Python 3:
- calories = int(input("Enter number of calories: "))
- fats = int(input("Enter number of fat in grams: "))
-
- if(calories > 0 and fats > 0):
- cf = fats * 9
- if(cf < calories):
- percent = cf / calories
- if(percent < 0.3):
- print("Food is low in fat")
- else:
- print("Error input. Calories from fat cannot more than total calories")
- else:
- print("Error input. Calories and fats must be more than 0")
Explanation:
Firstly, use input function to ask user to enter total number of calories and fat in grams (Line 1-2)
Next we do the first input validation to check if the calories and fats are more than 0 (Line 4). If so apply formula to calculate calories from fats. If not, print error input message (Line 5, 13)
Then we proceed to next input validation to check if calories from fact more than total calories. If so, proceed to calculate percentage of calories from fats and if it is lower than 30%, display the appropriate message (Line 6 - 9). If fail the second input validation, the program will display another error input message again (Line 11)
