In a sale, the selling price of a printer is reduced by 20%. Find the sale price of the printer, given that its normal selling price is 3600.

Step-by-step explanation:

1 - 0.2 = 0.8

0.8*3600= 2880

3600-2880= 720

Hope this helped!

ps. if the price had been increased you have to do 1+0.2= 1.2 then times this by 3600.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
