Suppose a railroad rail is 2 kilometers and it expands on a hot day by 19 centimeters in length. approximately how many meters would the center of the rail rise above the ground?

rail rise approximately 0.19 m above the ground

Step-by-step explanation:

as we know that

1m=100cm

and 1cm= m

similarly

19cm=m

19cm=0.19m

rail rise approximately 0.19 m above the ground

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
