The supplement of 89° is the angle that when added to 89° forms a straight angle (180° ).
Printer A
y = 14x
Printer B
Time(min) | 3 | 5 | 8 | 12 |
Pages printed | 48 | 80 | 128 | 192 |
Printer A prints 14(1) = 14 pages per minute.
Printer B prints 48/3 = 16 pages per minute.
The printer that prints at a faster rate is printer B.
If Sally paints one room per six hours, she paints 1/6 of the room every hour. Similarly, Steve paints 1/9 of the room every hour. Therefore, together, they paint 1/6+1/9=5/18 of the room every hour. Therefore, it takes the 18/5 of an hour to paint the whole room, since 18/5*5/18=1, so 18/5 of an hour at 5/18 of the room per hour is one room.
