Two times the quantity of seven less than one-fourth of a number is equal to four more than one-third of the number. What is the number?

The number is 17

Step-by-step explanation:

Let the number be x;

2(7) - x = 4 + x

Simplifying gives,

14 - 0.25x = 4 + x

14 - 4 = x + x

10 = x

10 = x

x = 120 ÷ 7 = 17

answer:      

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 !
