Which of the following pairs of ratios are equivalent? 1) 38 : 133 and 16 : 56 , 2) 15 : 20 and 28 : 56

38 : 133 and 16 : 56 are equivalent

Step-by-step explanation:

Given

1) and

2) and

Required

Determine which is equivalent

1) and

Divide by 19

--- can't be further simplified

Divide by 8

Hence:

and are equivalent

2) and

Divide by 5

Divide by 28

Hence, both are not equivalent.

answer: 59

step-by-step explanation:

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.
