A book is marked down by 28 percent from an original price of $19.50. What is the new price?

$14.04

Step-by-step explanation:

100 percent minus 28 percent is 72 percent.

Use the cross multiply format so it looks something like this: 72/100 = ?/19.50

Multiply 19.50 by 72.  You should get 1404

Divide by 100 to get 14.04. :)

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

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 !
