H= .6.5

V=<span>πr^2h

h=  v/</span>πr^2 = 2940.5/<span>π*12^2 = 6.49993 = 6.5</span>

Answer:

4,151,347,200

Step-by-step explanation:

To find how many ways the train can be made up we use the permutation formula and the values given.

n = 16

k = 9

_{n}P_{k}=\dfrac{n!}{(n-k)!}

_{16}P_{9}=\dfrac{16!}{(16-9)!}

_{16}P_{9}=\dfrac{16!}{7!}

_{16}P_{9}=4,151,347,200

So there will be 4,151,347,200 different ways that the train can be made.

Answer:

The value that will create an equation with no solutions is 5x.

Step-by-step explanation:

No solution would mean that there is no answer to the equation. It is impossible for the equation to be  true no matter what value we assign to the variable.

To create a no solution equation, we can need to create a mathematical statement that is always false.  To do this, we need the variables on both sides of the equation to cancel each other out and have the remaining  values to not be equal.

Use distributive property on the left side first.

3(x - 4) = [blank] - 2x +7\\\\3x-12=5x - 2x +7\\\\3x-12=3x+7\\\\3x-12+12=3x+7+12\\\\3x=3x+19\\\\3x-3x=3x+19-3x\\\\0=19

Notice that we combined like terms first and then eliminated the variable from one side. When that  happened, the variable on the other side was eliminated as well, giving us a false result.

Since zero does not equal nineteen, we know we have an equation with no solution.
