Dont let the sample of 500 teachers fool you the 500 teachers opinion is on their students standardized testing experience. In this case the students are the test subjects(population).
Distance covered in 1 rotation = circumference of the wheel
= 2r
= 2 x x 14
= 2 x 22 x 2
= 88 inches
Distance covered in 10 rotations = 88 x 10 = 880 inches
Therefore, the bike covers 880 inches after 10 rotations.
Since bc = 6, that makes db = 3 and cd = 3rad3
cd (2) = ac. so ac = 6rad3
so to get ad, you square ac which = 108, square cd which = 3rad3 which equals 27. 108 - 27 = 81. the sqaure root of 81 is 9. ad = 9
Answer: c) x = 5
