Julio's dad owns a restaurant. he bought 9 dozen potatoes to make french fries. he needs 7 potatoes for a large order of fries. how many large orders of fires will he be able to make?
i multiplied 9x12=108
then divided 108/7
i got 15 with 3 left over. is this right?

  yes, your math is correct

  15 large orders of fries can be made

Step-by-step explanation:

There are two questions here: one in the question you're trying to answer, and one that you have asked about your math. Hence, there are two answers here.

__

9 dozen divided by 7 is ...

  9·12/7 = 15 3/7

Julio's dad will be able to make 15 large orders of fries.

Your math is correct, but you need to be sure you answer the question asked, preferably in at least one complete sentence. Pay attention to the question wording.

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.
