The answer is 4939.22 but i’m not sure what this is so the nearest hundredth lol sorry :(
Answer:
B
Step-by-step explanation:
if y = -3 then 4+(-3)/4(-3) would be 4-3 = -1 over -12 so -1/-12 or 1/12 -->B
Mean, or average, is solved by adding all the numbers and dividing by the number of numbers. The answer is 88.
That would be 644.8 / 31 = 20.8 feet / second
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.
