1/3 of 30 is 10 because you dividing it by 3 and you would get 10.
Now 2/3 of 10 :
10/3=3.3 (2/3 so we have to multiply by 2) 3.3•2=6.6
6.6 has to be estimated because you can't have 6.6 people.
Your answer would be 6. Before I said 7 but you said I was incorrect so the only possibility left is 6.
Hoped I helped!
"c" is the hypotenuse of the largest triangle, and "a" is that triangle's shortest side. Thus the ratio is
... (longest side)/(shortest side)
Since all the triangles in the figure are similar, to complete the proportion, you need to recognize the triangle that "a" is the longest side of, then find the shortest side of that triangle.
"a" is the longest side (hypotenuse) of the smallest triangle. The shortest side of that triangle is "r". So, your proportion is ...
... c/a = a/r
The appropriate choice is the 2nd one, ...
... r
I think it’s q12 or C hope this helped
You didn’t post an image of the graph..
C because you factor it out
