Mrs chapman made vests for a cast members of the school play she used 3/4 yards of martial for each vest she used 6 yeards in all how many vest did she make vest

8 vests

Step-by-step explanation:

Mrs Chapman used 3/4 yards of martial for 1 vest.

When she used 6 yards, we are told to calculate the number of vest she made.

3/4 yards = 1vest

6 yards = y

We represent the number of vest made with y.

(3/4) / 6 = 1 / y

0.75/6 = 1/y

Cross multiply

0.75y = 6

Divide both side by 0.75

0.75y/0.75 = 6/0.75

y = 8

She will make 8 vests from 6 yards.

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.
