Answer:
16 seconds or 4/15 minutes
Step-by-step explanation:
first you would want to find how many seconds per hour by dividing 120 (the amount of seconds in two minutes) by 15 (the amount of hours)
120/15 =8 seconds per hour
Next, multiply 8 by the number of minutes which is two in this case and you will get 16 seconds. converted into minutes this is 4/15
c??
70%
there are 20 total marbles and only 14 are not blue so 14/20 = 7/10 = 70%
r(14) = 29
r(x) = 3/2x+8
r(14) = 3/2*14+8 = 21+8 = 29
