60 minutes. Take how far it is above ground (20 m) and add it to the absolute value of how far it is below ground (340 m) to get 360 meters, which you divide by the rate of descent (6 m/min) to get 60 minutes.
In order to prove that two lines are parallel to each other, you need to show that they have the same slope.
Line 1 is perpendicular to a line that has slope m, thus it has a slope of -1/m.
Line 2 is perpendicular to the same line with slope m, thus it has a slope of -1/m.
Line 1 and Line 2 have the same slope so they are parallel.
The possible outcomes where the red die shows a 3 are: (red, blue) = (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6).

Step-by-step explanation:
Answer:
552
Step-by-step explanation:
This is a problem of permutation which can be solved by rule of fundamental counting principle.
This principle states that if there "m" ways of doing one thing and "n" ways of doing other. Then no. of ways in which both the things can be done together is "m*n". This can be extended for m, n, p,r, s things and so on.
example: if there are 5 shirts and 3 trousers then number of ways in which the shirts and trousers can be worn is 5*3 = 15 ways.

The given problem is on similar concepts.
here 6 short stories, 4 novels, and 23 poems have to be assigned to his class.
Thus it can be done in 6*4*23 = 552 ways.
