Read the following code used to calculate the percentage of calories from fat in an item: calories = input("how many calories are in the item? ") caloriesfat = input("how many calories are from fat? ") percentfat = caloriesfat / calories there is an error in the code. what type of function needs to be used? float() [i think it is this one. is it right? ] int() print() [not this one! ] str()

The answer is int ()

Explanation:

Process of elimination. Only int and float are used for calculation (division obvs falls under that). Disregard the other two options. Float is for numerical values with a decimal. Calories are never shown with decimal points. So, it's int()

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
