A patrolman gives a driver a speeding ticket if the driver’s speed is greater than 15% over the posted speed limit. If the speed limit is 40 miles per hour, what is the highest speed that a driver can go without receiving a ticket?

No faster than 46 mph

Step-by-step explanation:

40*.15=6

6+40=46

(This is assuming they can go 15% over the speed limit and not that the car needs to be below 15% over the soeed limit)

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
