300; Since EF is the only segment not included in FHE, just subtract the 60 degrees there from 360 to get the sum of the rest of the circle

360-60 = 300

Hopefully this is right, i'm a little rusty on geometry

What is the average amount of milk used for an order of pancakes? Enter your answer as a fraction or mixed number in simplest form.

1/2c, 1/4c, 1/2c, 3/4c, 1/2c, 3/4c, 1/2c, 1/4c, 1/2c, 1/2c

Answer:

1/2c

Step-by-step explanation:

Taking the sum :

1/2c + 1/4c + 1/2c + 3/4c + 1/2c + 3/4c + 1/2c + 1/4c + 1/2c + 1/2c = 6/2c + 2/4c + 6/4c

6/2c + 2/4c + 6/4c

3/1 + 1/2 + 3/2 = (6 + 1 + 3) / 2 = 10 /2

= 5

Total number of orders = 10

Average = 5 / 10 = 1 /2 c
