Answer: large pizza
Work:
1) You can determine the arc of a slice that is 1/12 of the whole pizza using the diameter.
2) First, calculate the total circumference of each pizza.
Formula for the circumference: 2π×radius
radius = diameter / 2
medium pizza: 2π (12 / 2) = 12π ≈ 37.70 in
large pizza: 2π (16/2) = 16π ≈ 50.27 in
3) arc of a 1/12 sector
arc of a 1/12 sector = circumferece × 1/12
medium pizza: 37.70 in / 12 = 3.14 in
large pizza: 50.27 in / 12 = 4.19 ↔ this is pretty close to 4.25
So, at the end we have found that the sector of 4.25 in left belongs to a large pizza.

Answer:
13 1/8
Step-by-step explanation:
3/2* 7/2*5/2
= 105/8
= 13 1/8

See below
Step-by-step explanation:
She could have each student in the class write his or her name on a slip of paper and put it in a bowl. Then, she could shake the bowl and pull out any slip of paper with a student's name on it. After 3 times, the random sample would be over, and Mrs. Purdue would have her 3 representatives.
Ok she can buy 1 ten and 25 ones, 2 tens 15 ones, 3 tens 5 ones, and 35 ones. (Pretty sure)
