The correct answer is 20.7 inches of snow
Explanation:
The chart registers the total of snowfall at the school, in this, you can observe the total of snow in December was 3.4 inches, while in January the total was 12.3 and in February it was 8.4. Additionally, if you want to know the total during January and February combined the correct process is to add the two numbers. This means 12.3 inches (January) + 8.4 inches (February) = 20. 7 inches (Total in January and February.) Thus, the answer is 20.7 inches of snow.
Answer:
W=4 l=16
Step-by-step explanation:
Let w = width
Let l = length
Since the length is 4 times the width, l=4w
Perimeter of rectangle = 2l + 2w
= 2(4w)+2w
=10w
The perimeter of the rectangle =40, so
40=10w and w=4
Plug w into the length equation : l=4w=4(4)=16
The simple formula for velocity is v=d/t. Velocity equals distance divided by time. 360 miles divided by 180 minutes. 360/180=2. The car travels at 2 miles per MINUTE.
Now, to change to miles per HOUR. There are 60 minutes in an hour, so 2*60=120 miles per hour.
Answer: 120 mph
