So let’s say your doing a problem like mine for instance: Shelly buys 3 cabinets worth 40.89$
and a chair for 27.98$
But you do all the work in your head
And you come out with something like 50.089 now in cents you can’t have anything beyond three numbers after the decimal so what would you do in this instance?

Round

Step-by-step explanation:

Round to the nearest cent (in this case 50 dollars and 9 cents)

150.65 is the answer

Step-by-step explanation:

You multiply 40.89 x 3 (122.67) then add 27.98.

And maybe do it on a paper

answer: true

step-by-step explanation:

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
