10°c
Explanation:
Given parameter;
Lower fixed point = 30mm
Upper fixed point = 180mm
Reading = 45mm
Unknown:
The degree celcuis temperature at 45mm = ?
Solution:
To solve this problem we simply compare the mm- scale to the celcius - scale that we know.
The upper fixed point is the boiling point of water
Lower fixed point is the freezing point of water
This shows that both the upper and lower fixed point of both thermometers are the same;
mm-scale °c scale
180mm 100°c
45mm x
30mm 0°c
Solving;

x (150) = 100 x 15
x = 10°c

I do not know if it is correct but I think it is between B or C
A quadratic equation is a parabola and a linear equation is a straight line.
- Quadratic Equation is an equation in which the power of variable mostly x is two.
- Standard quadratic equation is

- Any linear equation have form like

- The moon has no atmosphere, no weather and no oceans of water. Its surface is in a perpetual vacuum.
- Because the moon's gravity is only one-sixth that of the Earth's gravity, Apollo astronauts had to risk of stumbling or falling.
- Astronauts on the moon were protected from the extreme temperatures by their spacesuits. The suits had several layers of insulating material covered by a highly reflective outer layer.

Answer:
The formula for calculating weight is F = m × 9.8 m/s2, where F is the object's weight in Newtons (N) and m is the object's mass in kilograms.
