An art teacher has 47 1/3 pounds of clay. he wants to give each student in his class 2 1/2 pounds of clay. The teacher estimates that he has enough clay for 9 students. Is this the best estimates explain

47 1/3 = 142 / 3      total clay

2 1/2 = 5 / 2      clay required for each student

If we divide total clay by clay per student

(142 / 3) / (5 / 2) = 284 / 15 = 18.9

So he should have enough clay for 18 students

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.
