Answer:
900
Step-by-step explanation:
Answer:
The radius is always half of the diameter.
Step-by-step explanation:
2 lines parallel, and 2 triangles have a common angle
So the smaller Δ is similar to the bigger Δ (AA Similarity)
9:(4x-2)+9=12:(3x+2)+12
9:4x+7=12:3x+14
9(3x+14)=12(4x+7)
27x+126=48x+84
21x=42
x=2
So the answer is x=2
No 12.14 is not bigger than 12.44
12.14 < 12.44
100 + 48=148 so that means she got 48 dollars for babysitting
