Does a angle have infinite length?

An angle has no length at all. The angle is just the amount of opening between

the two lines where they meet. The length of the angle's sides is completely

irrelevant, and has no effect at all on the measure of the angle. They can be

any length from almost zero to infinite, and they don't even have to both be

the same length. It just doesn't matter. None of that changes the measure of

the angle.

What is 1.000015 as a fraction?

To express 1.000015 as a fraction, we first note that the decimal has six decimal places. To convert this decimal to a fraction, we can write it as 1 + 0.000015. This can be simplified to 1 + 15/1,000,000. Combining the whole number and the fraction, we get 1,000,015/1,000,000 as the fraction equivalent of 1.000015.

How do you convert 0.125 into a mixed fraction?

To convert 0.125 into a mixed fraction, you first need to express it as a fraction. Since 0.125 is equivalent to 125/1000, you can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 125. This simplifies to 1/8. Therefore, the mixed fraction form of 0.125 is 1 1/8.

What is the average speed of a sprinter who runs 100 meters in 10 seconds?

I think it may be 22.37 miles per hour if I have got my Maths correct. He does 36,000 metres in an hour which is 360 x 100. So you divide 36,000 x 1609 (metres in a mile) and you get 22.37. So it is 22.37 miles per hour.

Order of rotational symmetry on an oval?

Oh, dude, an oval has an infinite number of lines of symmetry, so technically it has infinite rotational symmetry. But like, who's really gonna sit there and rotate an oval forever just to prove a point, right? So, yeah, infinite rotational symmetry for the win!

The sum of two numbers is 28 and their product is 180. Find the numbers?

Oh, dude, let's break out the math skills for this one. So, we know the sum of the two numbers is 28 and their product is 180. Let's call the numbers x and y. We can set up a system of equations: x + y = 28 and xy = 180. By solving these equations simultaneously, we find the numbers are 18 and 10. Easy peasy, lemon squeezy!

What is expanded form of 3.2?

The expanded form of 3.2 is 3 + 0.2. This is because the digit 3 is in the tens place, and the digit 2 is in the tenths place. In expanded form, each digit is shown with its positional value, so 3 represents 3 tens and 0.2 represents 2 tenths.

What is the LCM of a3b2 and a2b5?

The answer is a^2b^2, because the smallest exponent of the a's is 2 and the same thing with the b's. Therefore, that's the LCM (or least common multiple), because it is the smallest value the two terms share with one another. **When writing an exponent on a computer, you use a carrot (^) to represent the exponent.
