Answer:
6) x=9.75
10) Triangle OMN ~ Triangle ODK; SSS ~
11) SSS ~ theorem
12) SSS ~ theorem
Step-by-step explanation:
For #6, since the polygons are similar, then it must mean AD is congruent to JM and CD is congruent to LM. Now we can set up the proportion 39/20=x/5 and solve. Solving for x gets us x=9.75, so C is the correct choice
For #10, there's no information about angles whatsoever in the diagram, so B and C must be wrong. D must be wrong as well because if the triangles weren't similar, then why is OJ ~ JM and OK ~ KN? So thus, the triangles are similar by SSS.
For #11, this is sort of a no-brainer because there's no mention of angles, so D must be correct.
For #12, same concept, no mention of angles, all sides are similar to their respective sides of the different triangles, so A is correct.
The order from least to greatest is "forty percent, 0.5, eight-ninths, six-fifths".
<h3>What is a fraction?</h3>
A fraction is a part of the whole represented by a/b, where a and b are any integers.
The given numbers are,
six fifths = 6/5 = 1.2
eight ninths = 8/9 = 0.9
0.5
40% = 0.4
Therefore, the order from least to greatest is "forty percent, 0.5, eight-ninths, six-fifths".
