Q. A copy machine can print 405 copies in one minute. How many copies can be produced in 35 minutes

Hi there!

We know that a machine can print 405 copies in 1 minute. We are looking for how many can be made in 35 minutes. 35 minutes is 35 times greater than 1 minute, because if you have 1 35 times, you get 35.

This means that there will be 35 times more copies made in 35 minutes than in 1 minute. We know that there are 405 copies made in 1 minute, thus, in 35 minutes there would be 35 * 405 copies made, which is the same as taking 405 and adding it to itself 35 times.

Doing this, we get:

35 * 405 = 14175 copies

Hope this helps!

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
