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.

2.50c+6a=6344.50 <br> Find each variable
Ksju [112]

Answer:

c=2.4a+2537.8

a=-2.5/6c+1057.4

Step-by-step explanation:

solve for c:

2.50c+6a=6344.50

          -6a         -6a

2.50c=-6a+6344.50

/2.50       /2.50      /2.50

c=2.4a+2537.8

solve for a:

2.50c+6a=6344.50

-2.5c                -2.5c

6a=-2.5c+6344.50

/6       /6       /6

a=-2.5/6c+1057.4

Step-by-step explanation:

for such regular figures the volume is always

ground area × height.

the volume of the green box (bar on a rectangle) at the bottom is therefore

16×7×3 = 336 in³

the volume of the red object on top (based on a right-angled triangle) we get

5×3/2 × 6 = 5×3×3 = 45 in³

so, the total volume is the sum of both sub-volumes :

336 + 45 = 381 in³
