One brand of canned salmon is sold in four different sizes. size a the 7 1 5 -ounce can costs $3.49. size b the 16 1 2 -ounce can costs $6.49. size c the 24 3 4 -ounce can costs $8.49. size d the 30 2 3 -ounce can costs $10.99. what is the unit rate for each size to the nearest cent? if the cost is less than a dollar, put a zero to the left of the decimal point. size unit rate a $ b $ c $ d $ which size is the best buy? explain how you know.

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.

step-by-step explanation:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
