Marris decides to bake his parents a cookie in the shape of a regular dodecagon (12‑gon) for their 12-day anniversary. A.)If the edge of the dodecagon is 6 cm, what is the area of the top of the cookie? B) His parents decides to divide the cookie into 12 congruent pieces. After nine of the pieces have been eaten, what area of the cookie is left?

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

b

step-by-step explanation:

50- 250 is correct i did that one too

step-by-step explanation:

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363
