Let l and w be the length and width of the rectangle. We know that 
The formula for the perimeter is 
Using our substitution, it becomes
We know that the perimeter is 34, so we have
The length is 4 less than twice the width, so we have
Answer:
14
Step-by-step explanation:
We can see that the spinner is spun 50 times if we add all the "times spun" up.
7 + 8 + 7 + 8 + 11 + 9 = 50
So if we multiply this by 2, we should get the theoretical probability that 1 will be spun if the spinner was spun 100 times.
1 was spun 7 times when we spun the spinner 50 times, so we can predict that 1 will be spun 14 times if we spin the spinner 100 times.
You are looking for a speed in miles per hour, so start by converting 90 minutes into hours.
90/60 = 1.5
90 minutes = 1.5 hours
speed = distance/time = (105 miles)/(1.5 hours) = 70 mph
Answer:
36/16
