1. Four muffins cost $12. Which model shows how to find the cost per muffin?​

answer is A

Step-by-step explanation:

12/4 is 3. 3 dollars per muffin

C.

Step-by-step explanation:

This is your answer because on the "dollars" row, there are 12 squares, just like there are $12 and on "muffins" there are four squares just like there are 4 muffins.

each side has a different length.  

step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
