Employee has available sick time 4.21 but she used 3.30 so what the the balance left?

She has .91 left.

4.21 minus 3.30 equals .91.

Check work:

4.21

3.30

0.91

(1 minus 0 is 1, 2 gets turned into 12-3 and the 4 got turned to a 3. 12-3 is 9, and 3-3 is zero. Then you just carry down the decimal)

Hope this helps! :)

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
