Percent:

Fraction:

Percent: to the nearest percent 56% or 55.5555555556%

Step-by-step explanation:

There are nine total parts and 5 of those parts are shaded

You would divide 5 by 9 to get the percent then multiply it by 100

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

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.
