Is that the only statement. Or is there different options?
six pipes are laid end to end to form a row. Each pipe is 9 1/3 inches long. how long is the row of pipes, in feet?
Answer:
4.67 feet or 4 feet 8 inches or 
feet
Step-by-step explanation:
Let x be the length of the row pipes.
Given:
Number of pipes = 6
Each pipe has length 
inches. and six pipes are laid end to end to form a row.
The total length of the row is equal to length of the 6 pipes.
So, total length of row = Number of pipes 
Length of the pipe
inches
convert inch into feet.
Therefore, The length of the row is 4.67 feet or 4 feet 8 inches or feet .
Answer:
5x + 2
Step-by-step explanation:
(4x - 3)(x + 5)
Start by combining like terms.
4x + x = 5x -3 + 5 = 2
5x + 2
Kevin would probably leave it all to renee because he's lazy but that's not the question. Te answer is 3 and a half hours because it is the mean (average) of 3 and 4.
Hope this helps :)
Answer:
Prob.3
Denote r: radius of circle O
Formula for calculating AOB sector:
Area = pi*r^2*angle/360
Area = pi*r^2*45/360 = 18 pi
=> r^2 = 18*360/45 = 144
=> r = 12
For prob.4, give it a try, follow the formula I gave. Good luck !
(answer : r = 6)
