An operation has a 20 percent scrap rate. as a result, 80 pieces per hour are produced. what is the potential labor productivity that could be achieved by eliminating the scrap?

25%

Explanation:

If there is 20% scrap, then

80% of (production + scrap) = 72 pcs/hr

Now,

The percent increase in labor productivity is, .

Or it can be written as  25% of  which would give 80 pieces per hour.                                            

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
