Over the course of a day you checked 250 total mousetraps and determined that 50 of them were perfectly made. approximately what percentage of the mouse traps you check was perfectly made

20%

Step-by-step explanation:

Given : Over the course of a day you checked 250 total mousetraps and determined that 50 of them were perfectly made.

To Find: what percentage of the mouse traps you check was perfectly made?

Solution:

Total no. of mousetraps =250

Out of 250, 50 were perfectly made.

So, to find percentage of the mouse traps you check was perfectly made:

Hence 20% of the mouse traps you check was perfectly made

- "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."
