Answer:
50.40
Step-by-step explanation:
7 hours and 20 minutes times 7= 50 hours and 40 minutes
And then you have to change it into a mixed number and it is 50.40
see the attached figure to better understand the problem
we know that
The volume of the cone is equal to

in this problem

Substitute the values in the formula above

therefore
the answer is
The volume of the nose cone is 
Answer: 23.8 to three s.f
The range of a function is representative of the values on the y-axis. In this case, the graph will contain distance on the y-axis at is the dependent variable, while the independent variable is time.
We know that the minimum value of the distance will be 0, given that there can be no negative distance. Moreover, the maximum value is 26.2 miles, since the marathon will then be over. Therefore, a good range for the situation will be 0-27 miles.
Vertex form 1/2(0), where 0 replaces x as a number the variable x is.
The vertex is (0,0).
