John buys a pizza that has an 8-inch diameter and is cut into 12 congruent slices. What is the length of the outer edge of any one slice of pizza, in inches?

D. 2/3π inch

Step-by-step explanation:

360°/12=30° each slice of pizza is 30°.since they are all congruent:

c= 2πr*30°/360°

c=2(4)π* 1/12

c=8π/12

c=2/3π inch

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
