A copy machine makes 24 copies per minute. how many copies does it make in 5 minutes and 30 seconds
enot [183]
In 1 minute the copy machine copies = 24
That means
In 60 seconds the copy machine copies = 24
First we need to convert 5 minutes and 30 seconds to seconds
Then
5 minutes and 30 seconds = (5 * 60) + 30
                                           = 300 + 30
                                           = 330 seconds
So
In 330 seconds the copy machine will copy = (24/60) * 330
                                                                     = 4 * 33
                                                                     = 132
So in 5 minutes and 30 seconds the copy machine will copy 132 copies.

HEEEEEELP !

If you meant to write y=23x-4 then none of the lines are perpendicular.

I suspect you intended y=2/3x-4, then line D, y=-3/2x-4 is perpendicular.

For any line y=mx+b, you have to "invert" m to get  a perpendicular line. Inverting in this case means: flip numerator and denominator and add a minus sign.

So 2/3 becomes -3/2, hence answer D.

The 'inverted' m is called the opposite reciprocal. That's your word of the day.
