In the welding operations of a bicycle manufacturer, a bike frame has a long flow time. The set up for the bike frame is a 7 hour long operation. After the setup, the processing takes 6 hour(s). Finally, the bike frame waits in a storage space for 7 hours before sold. Determine the value-added percentage of the flow time for this bike frame. Round your answer to the nearest whole number for percentage and do NOT include the "%" sign in the answer. For example, if your answer is 17.7%, please answer 18. If your answer is 17.4%, please answer 17. No "%" sign. No letter. No symbols. No explanation. Just an integer number.
Answers
Answer:
Bike Frame Flow Time
The value-added percentage of the flow time for this bike frame is:
= 46.
Explanation:
a) Data and Calculations:
Bike Frame Flow Time:
Setup time = 7 hours
Processing time = 6 hours
Storage time = 7 hours
Flow time of the bike frame = 13 hours (7 + 6)
Value-added percentage of the flow time for this bike frame = 6/13 * 100
= 46%
b) Flow time represents the amount of time a bicycle frame spends in the manufacturing process from setup to end. It is called the total processing time. Unless there is one path through the process, the flow time equals the length of the longest process path. The storage time is not included in the flow time since it is not a manufacturing process.

Explanation:
The Boolean expression that tests if the value stored in the variable num1 is equal to the value stored in the variable num2 can be found in explanation.
What is boolean expression?A logical statement that could be either true or false is referred to as a Boolean expression.
As long as both parts of the expression have the same basic data type, Boolean expressions can compare data of any type. Data can be tested to see if it is the same as, greater than, or less than other data.
A Boolean expression is a type of expression used in programming languages that produces a Boolean value when evaluated. A Boolean value can only be true or false.
The boolean expression for the given scenario can be:
num1 = int(input("Enter value: "))
num2 = int(input("Enter value: "))
if num1 == num2:
print("Equals.")
else:
print("Unequal.")
