DIA [1.3K]

Answer:

Step-by-step explanation:

Angle  BCA is inscribed in that circle.  The rule is that the inscribed angle is half the measure of the arc it intercepts.  The arc it intercepts is arc AB which measures 96 degrees.  That means that

4x+4=\frac{1}{2}(96) and

4x + 4 = 48 and

4x = 44 so

x = 11

Choice A is the one you want.

A website charges $3 for each movie you download. They also charge a one-time sign-up fee of $14.99.
Igoryamba
I am sorry, but nobody can help until you put the question. Assuming it is Algebra, I can write this as function which would be y = 3x + 14.99 . Also, x has to be greather than zero because you cannot undownload a movie. y can also be something like f (m). m means the movies you downloaded. So it could also be f = 3m + 14.99 . If you want to graph it, I could do it for you.

Charra [1.4K]
Since we know the person in the problem has been working for 24 years, and 1/2 of his life, we can conclude that the man is 48 years old. This is because if half of the mans life was 24 years, we have to multiply the number by 2. The correct answer is 48.
