Jeff hiked for 2 hours and traveled 5 miles. If he continues at the same pace, which equation will show the relationship between
the time, t, in hours he hikes to distance, d, in miles? Will the graph be continuous or discrete?
2 answers:
Answer: The relationship between distance and time is and the graph is continuous.
Step-by-step explanation:
Since we have given that
Number of hours he hiked = 2 hours
Distance covered = 5 miles
Speed would be
Let the distance be 'd'.
Let the time be 't'.
so, the relation between distance and time would be
The graph is continuous because it is not based on counts and the points are connected with a continuous line without any break.
Hence, the relationship between distance and time is and the graph is continuous.

We will traduce the sentences into equations.
Let x be the number of hours in the first job, and y be the number of hours in the second job.
Then the equations are:
The above system has many solution, we can select for example:
x = 1, y = 16. So we can work one hour at the first job and 16 hour at the second job.
Let x be the number of hours in the first job, and y be the number of hours in the second job.
Then the equations are:

x = 1, y = 16. So we can work one hour at the first job and 16 hour at the second job.
Answer:
They encircle the planet times.
Step-by-step explanation:
Consider the provided information.
We have 2.5 mole of dust particles and the Avogadro's number is
Thus, the number of dust particles is:
Diameter of a dust particles is 10μm and the circumference of earth is 40,076 km.
Convert the measurement in meters.
Diameter:
If we line up the particles the distance they could cover is:
Circumference in meters:
Therefore,
Hence, they encircle the planet times.
