Answer:

Age ≥ 8

Step-by-step explanation:

On the number line there will be a solid circle on +8 with the arrow pointing right.

If people want to be very accurate, the line should end with an open circle on 18 because at that age, you are considered an adult.

The equation would look like 8≤ Age<18

Find the arc length of ABC .

Salsk061 [2.6K]

Answer:

Step-by-step explanation:

Since the radius of the circle is 12 units, we can calculate the circumference.

2 * pi * r = 2 * pi * 12 = 24 * pi = 24pi.

The arc angle is 240 degrees, and the whole circle would be 360 degrees. So, we can set up an equation.

$\frac{24\pi }{360} =\frac{x}{240}$

$\frac{24\pi }{6} =\frac{x}{4}$

$\frac{4\pi }{1} =\frac{x}{4}$

1 * x = 4 * 4 * pi

x = 16pi

So, your answer is C.

Hope this helps!
