The lock is numbered from 0 to 49. Each combination uses three numbers in a right, left, right pattern. Find the total number of possible combinations for the lock.

Answers

The correct answer is:

125,000.

Explanation:

For the first turn, there are 50 numbers to choose from.

On each turn of a lock, the numbers can be repeated; this means on the second turn, there are 50 numbers to choose from, and on the third turn, there are 50 numbers to choose from. This gives us:

50³ = 50×50×50 = 125,000.

Ali says if two lines share a point they cannot be parallel do you agree explain

Answers

Yes, parallel lines do not touch each other ever.

How are parallel straight lines related?

Parallellines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.

Since the given parallel line has equation y = 2x + 2, thus its slope is 2 and thus, the slope of the needed line is 2 too.

We are given that Ali says if two lines share a point they cannot be parallel .

Horizontal refers to something that goes parallel to ground level. Of course it depends on from where you see that thing.

When you slice an object horizontally, you cut it parallel to ground.

We know that parallel linesdo not touch each other ever.

so that's make ali statement correct.
