The fraction 1/3 means 1 out of 3 equally divided parts, so 12 needs to be equally divided into 3 groups. Have students divide the 12 stars into 3 equal groups. Each of the 3 equally divided groups is 1/3 of the total. Thus, 1/3 of 12 is the number in 1group, or 4.
C)66 because the whole angle is 176
Answer:
Unit rate by which the runner completed the marathon is 0.13 miles per minute.
Step-by-step explanation:
A runner competed a marathon of 26.2 miles in 210 minutes.
we can get unit rate by unitary method.
∵ In 210 minutes a runner completes the distance = 26.2 miles
∴ In 1 minute runner will complete the distance = 
= 0.125 miles per minute
≈ 0.13 miles per minute
Therefore, unit rate by which the runner completed the marathon is 0.13 miles per minute.
So, the right option is 1. so if my ans was helpful u can follow me.
In the equation

divide both sides by
to get

Take the base-3/2 logarithm of both sides:

Alternatively, you can divide both sides by
:

Then take the base-2/3 logarith of both sides to get

(Both answers are equivalent)
