Set up the proportion. That's what similar gives you the right to do.
(12 + 3) / 4x = 12 / (3x + 1) Cross multiply
15 * (3x + 1) = 12 * 4x Remove the brackets
45x + 15 = 48x Subtract 45x from both sides.
15 = 48x - 45x
15 = 3x
x = 5
Answer:
Step-by-step explanation:
The probability that the point is chosen in the circle is equal to the area of the circle divided by the area of the square.
Formulas used:
- Area of a square with side length is given by
- Area of a circle with radius is given by
The segment marked as 1 represents not only the radius of the circle, but also half the side length of the square. Therefore, the side length of the square is 2, and we have:
Area of square:
Area of circle:
Therefore, the probability that the point will be inside the circle is:
