Answer:
200 in the x-direction by -346 in the y-direction
Step-by-step explanation:
This vector lies in Quadrant IV.
The horiz. component is 400 cos (-60°) = 400(0.5) = 200, and
the vertical comp. is 400 sin (-60°) = 400(-0.866) = -346
The combination form is 200 in the x-direction by -346 in the y-direction, or (as a vector) <200, -346>
Answer:
$75
Step-by-step explanation:
let the original price be x
then,
80% of x = 60
80/100 of x = 60
therefore x = 75
Originally, you would get 6.56666 repeating as your answer. When you end up rounding, or estimating it, it then becomes just simply 7.
