If a marble is randomly chosen from a bag that contains exaclty 8 red marbles, 6 blue marbles and 6 white marbles, what is the probability that the marks will not be white?

14/20 or simplified as 7/10

Step-by-step explanation:

You add all of the numbers together to get the denominator.You add them together because it is like a 100% of the bag. The numerator is the percent out of the bag(except as a fraction). Then you count all of the marbles that aren't white. Then that will be the numerator.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
