A company has budgeted $21,200 to buy TV ads. A TV ad costs $6,575 per
minute. Estimate the number of minutes the company can purchase by rounding
each number to the nearest thousand.
minutes

about 300

21200 rounded is 21000 and 6575 rounded is 7000

Step-by-step explanation:

21000÷7000=300

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
