Answer:
Step-by-step explanation:
We know that:
- The initial conditions are -7 meters at 0 minutes.
- Then, after 6 minutes, he was 16 meters below the ground.
According to these two simple facts we can found the linear function that describes this problem. First, the problem says that Mr. Mole is descending at a constant rate, which is the slope of the function. Now, to calculate the slope we need to points, which are 
and 
, where <em>t-values </em>are minutes, and <em>y-values </em>are meters. You can see, that the first point is the initial condition and the second point is 6 minutes later.
So, we calculate the slope:
From the slope we can see that Mr. Mole is descending, because it has a negative sign. Also, the point is on the <em>y-axis</em>, because <em>t</em> is null, so -7 is part of the function. Therefore the function that describes this problem is:
Answer: The correct answer is option B: 19%
Step-by-step explanation: The bar graph according to the question has the following set of data;
Cereal ----------34
Eggs and Bacon ----------21
Pastries ----------39
Bagels ----------48
Waffles ----------38
The total from this set of data is 180 (that is the summation of all the observed data). The portion taken up by cereals can be derived as follows;
Cereal = (34/180) x 360
Cereal = 68 degrees
Note that we have used degrees as the unit since the data would be transferred to a pie chart. Hence on the pie chart it occupies 68 degrees of the entire 360 degrees.
In order to find out what percentage this represents we can now express 68 degrees as a percentage as follows;
Cereal = (68/360) x 100
Cereal = 18.8888888
Cereal ≈ 19
Therefore cereal occupies 19 percent of the pie chart.
