AM is a vertical radius. AB, AC are two chords representing two smooth rods in the circle where AC > AB. Two beads slide from rest point A such that one bead on the chord AB to reach B after time t1, and the other bead on the chord AC to reach C after time t2. Find the value of the ratio t1 : t2

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
