Answer:

There are 151,200 different ways.

Step-by-step explanation:

For solving this question, we need  the concept of permutation, the permutation gives as the number of ordered arrangement that can be made chosen k elements from a group of n elements. it is calculated as:

\frac{n!}{(n-k)!}

So, in this case, we need to find the number of ways in which 6 top participants from the 10 participants can cross the finish line.

Now, we can replace n by 10 and k by 6 and calculate the number of permutations as:

\frac{10!}{(10-6)!}=151,200

Finally, there are 151,200 different ways in which the top 6 cars can cross the finish line.

Two parallel lines are _____ coplanar.
dimulka [17.4K]

Answer:

1. always

2. sometimes

Step-by-step explanation:

Two lines are coplanar if they lie in the same plane or in parallel planes. There is  ALWAYS a plane which contains two parallel lines (see first attached image for details).

Two lines that lie in parallel planes are sometimes parallel. For example, see at second image. Planes \alpha and \beta are parallel. Consider pair of lines a and a_1 - they are parallel, but if you consider the pair of lines a and b_1, you can see they are not parallel.
