Abigail plans to save 2/5 of her earnings each week for 12 weeks. She earns approximately 180 per week about how much will Abigail have saved from earnings at the end 12 weeks

864

Step-by-step explanation:

Each week she will save 2/5, so 2/5 of 180 = (2/5)*180 = 72. Then, she is saving for 12 weeks and each week she saves 72 so at the end of 12 weeks: 72*12 = 864.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
