a car gets 27 miles per gallon in the city and 35 miles per gallon on the highway. what range of miles can the car travel on 3 g
Verdich [7]
The answer is 81 < < 105

Explanation: Since the car gets 27 mpg in the city and gets 35 mpg on the highway, you can set it up in the inequality 27 < < 35 and this represents the range a car can drive for 1 gallon, so to find the range for 3 gallons, you multiply this inequality by 3.

27(3)<<35(3)
27(3)=81
35(3)=105

Then you can insert the numbers into the inequality to get 81<<105.

What is the exact volume of the cone
Travka [436]

Answer:

V = \frac{400}{3}\pi

Step-by-step explanation:

Volume of a cone is:

V = \pi r^{2} \frac{h}{3}

Substitute values given:

V = \pi (5^{2} )(\frac{16}{3})

V = \pi (25)(\frac{16}{3} )

V = \pi \frac{400}{3}

V = \frac{400}{3}\pi
