A new car is purchased for 16900 dollars. The value of the car depreciates at 15% per year. What will the value of the car be, to the nearest cent, after 15 years ?

yes. we do proportions in probabilities.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

the answer is d

for problems like this theres an app, its photomath that explains the problem and gives the answer hope i

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
