Answer:
12
Step-by-step explanation:
To find perimeter, add the lengths of each side. 5 + 4 + 3 = 12
9 times 4.25 = 38.25 inches area of a rectangle is length times width
How long is the line between the two cities on the map? I see that you wrote 15/8 inches. That can't be right. If it is then the correct answer is not one of the choices. If it's really 15/8 inches then their average speed would be 48 miles per hour.
The probability of the 2 events are multiplied to get the result 10/91
so we have the relation 5/14 * x = 10/91
where x is the probability of drawing the second black
so x = 10/91 * 14/5 = 4/13 answer
