Choose one or more conversion factors that can best be used to convert 50 (km)/(myr)(kilometers per million years) to (cm)/(yr) (centimeters per year).
(100 cm)/(1 m)
(1 myr)/(1yr)
(1000 m)/(1 km)
(1 km)/(1000 m)
(1min)/(60sec)
(60 min)/(1 hr)
(1hr)/(60 min)

now convert 50 (km)/(myr)to )/(yr). (cm)/(yr)

50 km/Myr= 5 cm/yr

Step-by-step explanation:

We know that 1 km = 1000 m

And 1m = 100 cm

Therefore, 1 km = 100,000 m

Also, 1 million = 1,000,000

Therefore, 1 km/ Myr=

Hence, 50 km/ Myr = 5 cm/yr

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
