A copy machine was used to produce two smaller versions of a rectangular picture. Each dimension of the original picture was reduced by 20% to produce the first smaller version , and then each dimension of the first smaller version was reduced by 15% to produce the second smaller version. Each dimension of the second smaller version was what percent of the corresponding dimension of the original picture?

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
