jane is making a suit which requires 2 5⁄8 yards for the jacket and 1 3⁄4 yards for the skirt. what's the total amount of material she needs?

4 3/8 yards of material

Step-by-step explanation:

1. Convert both to same demonimators

    1 3/4 = 1 6/8

2. Add the fractions together: 2 5/8 + 1 6/8 = 3 11/8

3. Convert the improper fraction to mixed number and add to the whole number (3).

4. 1 3/8 + 3 = 4 3/8

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.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
