Mary and Will rent a tandem bike for $10/hr. Which value is the dependent variable? Which is the independent variable? Write an
equation to represent the relationship between the number of
hours, h, and the total cost, c.

Step-by-step explanation:

c = 10h

h is the independent variable.

c is the dependent variable.

the answer is d

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
