One meter is equal to 100cm. So if you convert 2 meters into centimetres, it would be equal to 200cm. Now since you have a 200cm pipe and you want to see how many sections of 10cm you can cut, you can just divide. It’d be 200 divided by 10 which would be 20. Therefore, the pipe can be cut into 20 pieces.

Hope this helped!

What are the solutions to x^2-5x+3=0?
Viktor [21]

Answer:

Step-by-step explanation:

You need to use the quadratic equation

x =  \frac{-b +/- \sqrt{b^2 - 4ac} }{2a}

Givens

  • a = 1
  • b = - 5
  • c = 3

x = \frac{5 +/- \sqrt{5^2 - 4a*1*3} }{2} \\

x =( 5 +/- sqrt(25 - 12) ) / 2

x = (5 +/- sqrt(13) )/2

x = (5 + sqrt(13) / 2

x = 4.303  rounded

x = (5 - sqrt(13) ) /2

x = .6972
