Answer:
i.e. relation between speed-distance-time is one such situation that can be modeled using graph
Step-by-step explanation:
There are many real world examples that can be modeled using graph. Graphs are represented on co-ordinate planes, so any real world example that can be represented by use of linear equation can be represented onto a graph.
One such example, is speed-distance-time relation. Uniform speed can be represented on a graph as shown in figure.
So, the equation for speed is represented by equation as follows:
![Speed=distance/time](https://tex.z-dn.net/?f=Speed%3Ddistance%2Ftime)
So, if we take distance on y axis and time on x axis with points as (distance,time)
(0,0) ==> ![v=0/0=0](https://tex.z-dn.net/?f=v%3D0%2F0%3D0)
(1,2) ==> ![v=1/2=0.5](https://tex.z-dn.net/?f=v%3D1%2F2%3D0.5)
(2,2) ==> ![v=2/2=1](https://tex.z-dn.net/?f=v%3D2%2F2%3D1)
the following points 0,0.5,1 will be plotted on graph. Similarly, more values can be plotted by assuming values for distance and time.
Answer:
$84
Step-by-step explanation:
720x30=21600
21600/100=216
216=markdown (as a number instead of a percentage)
Now subtract that like this
720-216=504
504= sale price
Then do this
504-420=84
Therefore it is $84

Answer: 7/8
Step-by-step explanation:
If the ratio is vanilla to chocolate, it would be
42:48
Dividing by 2
= 21:24
Dividing by 3
= 7:8
