A chemist has a beaker with 4 fluid ounces of a solution. The chemist needs 500 milliliters for an experiment. About how many more milliliters does the chemist need?Use 1 fluid ounce = 29.6 milliliters

381.6 milliliters are still needed.

Step-by-step explanation:

1 fluid ounce = 29.6 mL

29.6 mL * 4 = 118.4 mL

4 ounces = 118.4 milliliters

500 mL - 118.4 mL = 381.6 mL

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
