Answer:

The wheels have to rotate 500 times

Step-by-step explanation:

The wheel is 1 meter in diameter so we need to find the circumference.

C = 2 $\pi$ r

C = 2 $\pi$ 1

C= 2 $\pi$

2meters = .002kilometers

1000meters = 1kilometer

1000/2 = 500

Find the greatest common factor of 36 and 54

8090 [49]

Hey there!

To find the greatest common factor you will need to find all the factors of 36 and 54. (A factor is a number that can be divided into another number).

54 - 1, 2, 3, 6, 9, 18, 27.

36 - 1, 2, 3, 4, 6, 9, 12, 18.

As you can see here, the factor that is the greatest is 18. Therefore, that is your answer.

Hope this helps! :)

What is the simplified form of x+2/x^2-3x-10 * x-3/x^2+x-12

Vinvika [58]

I mean based on your possible answers, the third one is correct,but you can go further that that, in the steps i will note when you've came to the "answer"

$\frac{x + 2}{ {x}^{2} - 3x - 10 } \times \frac{x - 3}{ {x}^{2} + x - 12 }$
$\frac{x + 2}{ {x}^{2} + 2x - 5x - 10 } \times \frac{x - 3}{ {x}^{2} + 4x - 3x - 12 }$
$\frac{x + 2}{x(x + 2) - 5(x + 2)} \times \frac{x - 3}{x(x + 4) - 3(x + 4)}$
$\frac{x + 2}{(x + 2) \times (x - 5)} \times \frac{x - 3}{(x + 4) \times (x - 3)}$
$\frac{1}{(x + 4) \times (x + 5)}$
and basically that's the "answer", but you can simplify more.

$\frac{1}{ {x}^{2} + 4x - 5x - 20}$
$\frac{1}{ {x}^{2} - x - 20 }$
Hope that's helpful
