1. As you can see in the graph attached, the x axis represents the time in seconds and the y axis represents the height in meters.
2. Therefore, to solve this exercise and calculate <span>how many seconds is the nail 50 m above the ground, you must draw a segment from 50 meters to the curve and then, you need to draw another segment from that point at the curve, to the x axis, as it is shown in the figure attached.
3. You can conclude that </span>the nail is 50 meters above the ground<span> in 3.9 seconds.
Therefore, the answer is: 3.9 s</span>

Which graph shows: 
To do this, we simply check the intersection points of the lines on the graph.
This particular graph that is shown has as its solution because the point of intersection of both lines is at:
i.e.
Answer:
The combined average is 94%
Step-by-step explanation:
for first period, number of students =40
average =96%
for second period, no of students =20
average =90%
but 
let 
=sum of students for the first period
=sum of students for the second period
for first period;
for second period,
therefore the combined average = 
that is 
so combined average is 94%
