Can somebody help me?​

Mathematics
1 answer:
Mashcka [7]2 years ago
6 0

Answer:

6/7

Step-by-step explanation:

because there are 28 properties in all

4 of them are railroads

but we're not looking for the probability of selecting a railroad, which would be 4/28 or 1/7, but for not selecting a railroad

and 24 of them are not railroads

So the probability of not selecting a railroad is 24/28, which simplified/reduced is 6/7

What is the volume of the cylinder if the height is 2x+7 and the radius is x-3
shusha [124]

Answer:

Therefore the volume of the cylinder=\pi(2x^3-5x^2-24x+63)  cubic units

Step-by-step explanation:

Given height of a cylinder is (h) =2x+7

and radius  (r)= x-3

Volume of the cylinder = \pi r^2 h

                                  =\pi (x-3)^2(2x+7)

                                  =\pi (x^2-6x+9)(2x+7)

                                  =\pi (2x^3-12x^2+18x+7x^2-42x+63)

                                  =\pi(2x^3-5x^2-24x+63)  cubic units

Therefore the volume of the cylinder=\pi(2x^3-5x^2-24x+63)  cubic units
