Hi I need help with this question (see image ). Please show workings if necessary.

  63.4 °C

Explanation:

If we assume the "fixed points" are 0 °C and 100 °C, then the thermometer reading as a function of actual temperature can be described by a linear equation that must have (0, -0.5) and (100, 106) as solutions. We can use these points in the 2-point form of the equation for a line:

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (106 -(-0.5))/(100 -0)(x -0) -0.5

  y = 106.5x -0.5

Then, for x = 60, the thermometer reading is expected to be ...

  y = 106.5×60 -0.5 = 63.4 . . . °C

learn it on the intertant so you can solve

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
