The Pythagorean Theorem states that a^2+b^2=c^2
We already have:
A^2+6^2=117
All we need to do is find the missing A by subtract b from c.
117-36=81
Now the square root of 81, 9.
So, x is 9 cm.

Answer:

There are 604,800 possible permutations.

Step-by-step explanation:

The order in which the digits are chosen is important, which means that the permutations formula is used to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

In this question:

7 digits from a set of 10(10 digits to 0-9). So

$P_{(10,7)} = \frac{10!}{(10-7)!} = 604800$

There are 604,800 possible permutations.

Kiran wrote the expression x-10 for this number puzzle: "Pick a number, add -2, and multiply by 5."

ioda

Answer:

If you pick the number 2, you will get (2) - 10 = 8

But the way he said it, it would be: (2) - 2 * 5 = 0

The correct way would be to write the expression: (x - 3) * 5
