The batting wang xiu ying uses to fill quilts has a thermal conductivity rate of 0.03 watts (w) per meter(m) per degree celsius. what is the batting thermal conductivity when w/cm•c

We are given

a thermal conductivity rate of 0.03 watts (W) per meter(m) per degree celsius

so, thermal conductivity is

while we want the batting thermal conductivity in  w/cm•c

The only difference is that metre and cm

so, we need to change metre into centimeter

we know

1m =100cm

so, we can write thermal conductivity as

we can replace 1m as 100cm

now, we can simplify it

so, thermal conductivity is

................Answer

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
