Answer:
It would take him 60 minutes to run 20 laps.
Step-by-step explanation:
We can solve using proportions.
![\frac{9 \: laps}{27 \: minutes} = \frac{20 \: laps}{x} \\ \\ \frac{540}{9} = \frac{9x}{9} \\ \\ 60 = x](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%20%5C%3A%20laps%7D%7B27%20%5C%3A%20minutes%7D%20%20%3D%20%20%20%5Cfrac%7B20%20%5C%3A%20laps%7D%7Bx%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Cfrac%7B540%7D%7B9%7D%20%20%3D%20%20%5Cfrac%7B9x%7D%7B9%7D%20%20%5C%5C%20%20%5C%5C%2060%20%3D%20x)
It would take him 60 minutes.
Angl 6 measures out to be 62° as its corresponding with angle 8
There are 3 numbers as such.
First lets list all the factors of 12
1,2,3,4,6,12
now lets see which are multiples of 3
3,6 and 12 are multiples of 3
therefore we are left with
1,2 and 4
