Alexa can blow 15 balloons in 20 minutes. Sara can blow 18 balloons in 25 minutes, Shirley can blow 16 balloons in 21
minutes and Sam can blow 12 balloons in 23 minutes.

Assuming that all balloons are blown to the same size, who can blow
balloons at the fastest rate?

rate of blowing balloons of Alexa = 15/20 = 0.75

rate of blowing balloons of Sara = 18/25 = 0.72

rate of blowing balloons of Shirley= 16/21 = 0.76

rate of blowing balloons of Sam = 12/23 = 0.52

from above calculation we concluded Shirley can blow balloons at the fastest rate!

answer: 140

step-by-step explanation:

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people

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.
