Answer:
here's your answer - the angle of elevation
Answer:
50 minutes
Explanation:
We can set this up as a rate * time = distance problem. We can set the rate at which Amanda travels to work to be x, since that quantity is unknown. The time it takes is given to be 60 minutes. This means that the total distance she travels to get to work is 60x. On the other hand, the way back home has more unknown quantities. The exact rate is unknown, but we do know that it is 20% more than the rate at which Amanda travels to work. This means that the rate is x + .20x, or 1.2x. We can set the time to be y, which means the total distance she travels to get back home is 1.2xy. We are told that Amanda uses the same route to get to and from work, which means 60x = 1.2xy. All we have to do now is solve this equation:

If we divide through by x and then isolate y, we get that it takes Amanda 50 minutes to get home

i got it right on edge ma dudes
Answer:
Fuel 1 changed phase because the energy drawn from it dropped its temperature below the transitional temperature that causes a phase change, fuel 2 still has its temperature well above the transitional temperature required to change phase.
Explanation:
For a substance to change phase, a transitional temperature has to be reached. This is because, the temperature of substances generally indicates the average kinetic energy of its molecules. An increase in energy input to the system will result in a change to a more mobile phase like from solid to a liquid state or from a liquid state to a gaseous state state, while taking energy from the system will cause a transition to a less mobile phase like gas to liquid or liquid to solid state.
