Answer: 3.4 h
Explanation:
1) The basis to solve this kind of problems is that the speed of working together is equal to the sum of the individual speeds.
This is: speed of doing the project together = speed of Cody working alone + speed of Kaitlyin working alone.
2) Speed of Cody
Cody can complete the project in 8 hours => 1 project / 8 h
3) Speed of Kaitlyn
Kaitlyn can complete the project in 6 houres => 1 project / 6 h
4) Speed working together:
1 / 8 + 1 / 6 = [6 + 8] / (6*8 = 14 / 48 = 7 / 24
7/24 is the velocity or working together meaning that they can complete 7 projects in 24 hours.
Then, the time to complete the entire project is the inverse: 24 hours / 7 projects ≈ 3.4 hours / project.Meaning 3.4 hours to complete the project.
57 degrees because 180-123= 57 degrees
Answer:
The correct option is A.
Step-by-step explanation:
Consider the complete question is "The table shows the transportation method used by the employees in an office.
Transportation Number of employees
Car 18
Bus 6
Walk 6
what is the probability that the next two employees that join the office staff will take the bus? A.0.04, B.0.12, C.0.33, D.0.36.
Total number of employees = 18 + 6 + 6 = 30
The probability that the employees take the bus = 
The probability that the employees that join the office staff will take the bus is
Therefore, the correct option is A.
Answer:
A) true
Step-by-step explanation:
when you use the distributive property with the equation 4(2x + y + 6) you get 8x + 4y + 24
The answer would most likely be C
