This is actually called a mapping diagram but the answer is C.
Because the right circle represents the x variable and the left circle is the y variable. So you just follow the arrows. -3 is pointing to 4 so that's a pair or (-3,4)
20x-18x=6+8
2x=14
X=7
Answer
Answer:
≈ 78.55 cm
Step-by-step explanation:
Using the ratio of arc (AB) to circumference (C) is equal to the ratio of angle subtended at centre by arc AB to 360°, that is
= , that is
= ( cross- multiply )
110C = 8640 ( divide both sides by 110 )
C = ≈ 78.55 cm ( to 2 dec. places )
