2. Sara went to the store to buy 3 apples, 1 cabbage and four, 2-Liter of sodas. She has $15.47 with her. The apples are 89 cents each and the cabbage is $1.99 each. The 2-liter of soda is $2.99 each but on sale
for 99 cents each if you purchase 4 at one time. Sales tax is $2.24 if the total is below $10.00 and $4.24 if
the total is above $11.00. How much is the total cost of the food?
$9.43
$10.86
none of these
$14.24

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

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.
