The first composite shape we would need to find is the rectangle. We would use the formula length multiplied by width. The second composite shape is a hemisphere. The area of a hemisphere is Pi multiplied by the radius squared and then divide it by 2. To find the area of both of these figures, add up the area for each one and then you will get the
area of both.
An easy way is to work out their speed. Speed = distance/time.
First part: Speed = 330/5.5 = 60 mph
Finally, the second part: time = distance / speed
So time = 720/60 = 12 hours
40=10+2x where x is the number of dogs.
30=2x
x=15
Therefore she must walk 15 dogs
Hope this helps :)
The answer is “the cost for every 1 lawn mowed”. This is because the graph is showing an increase in price every time another lawn is mowed.
