Interesting problem. When computers first came out (when dinosaurs ruled the planet), we had to deal with problems that were many brackets deep. So this has practical applications.
Start at the very right and keep on removing brackets and collecting like terms.
5a - {3b - 5[a - (b - 4a)]} I just changed the sign on the right bracket.
5a - {3b - 5[a - b + 4a]}
5a - {3b - 5[5a - b]} Now deal with []. You are still on the right.
5a - {3b - 25a + 5b}
5a - {8b - 25a} Finally remove {}
5a - 8b + 25a
30a - 8b
If you can solve another like this, you are well on your way to being good in computer science.
The volume of the bucket will be given by:
v=πr²h
Thus the volume of our bucket will be:
v=3.14×(3.5)²×8
v=46.465 in³
thus the cost of the bucket will be:
cost=(cost per cubic volume)×(volume of bucket)
cost=46.465(0.05)=$2.32325~$2.30
Answer:
97 degrees
Step-by-step explanation:
180 degrees minus 83 degrees is 97 degrees
I think its the one when it says 'all factors were negatives' because if u have -1 times -1 tmes -1 times -1, for -1 to the 4th power, the result will be a positive one
65000 is the answer since you have to round to the nearest thousands
