Which expression correctly represents “six more than the product of five and a number, decreased by one
a.6+5n-1
b.6+5+n-1
c.6+5(n-1)
d.(6+5)n-1

Step-by-step explanation:

six more than the product of five and a number, decreased by one

Let the unknown number is 'n'

to get product we multiply

the product of five and a number is 5n

six more than the product of five and a number,

Decrease the final expression by one

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
