A regular decagon is rotated in degrees about its center carrying the decagon onto itself. the value of n could be

Step-by-step explanation:

Given:

Required

Determine the value of n

For a decagon:

First, we need to determine the angle of each rotation.

This is calculated by dividing the complete rotation with number of sides

Next, we calculate the possible value of n.

Since there is no option, the general rule is that the possible value of n must be a multiple of angle of each rotation i.e. 36

Hence, n could be either of the following:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!
