Answer:
200 minutes ; 3 hours and 20 minutes.
Step-by-step explanation:
If you write a proportion in the form
miles/minutes = miles/minutes
you would get 3/50 = 12/x
from there you cross multiply to get
3x=600, and solve that to get 200 minutes.
another way was to see that 12 is 3*4, and multiply 50 by 4 to get the same answer.
To convert a fraction to a percentage you multiply by 100.
(9 / 25) * 100
= 9 * 100/25
= 9 * 4
= 36% answer
Answer:
it would be C
Step-by-step explanation:
A trapiziod equals 360 degrees in total, so 110+110+70 is 290.
the total degrees 360-290 would give you 70 degrees, so C is correct.
