Christina estimated 188% of 91 by performing these steps. What did she do wrong? (90) (190 percent) = (90) (100 percent + 90 percent) = (90) (100 percent) + (90) (90 percent) = (90) (1.0) + (90) (0.9) = 90 + 18 = 108.
She rounded 188% up to 190%.
She rounded 91 down to 90.
She incorrectly broke 190% into 100 percent + 90 percent.
She incorrectly multiplied 90 and 0.9.

D) she incorrectly multiplyed 90 and 0.9.

hope this helps! i got 100 on the quiz on edge

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
