Answer: 318 2/3
OR
318 R 2
Answer:
16
Step-by-step explanation:
We can see that Ar is the perpendicular bisector of chord BD. Since A is the center of the circle, AR is the radius of the circle, which is 10 (6+4)
Next, we can see that when we connect point A to point D, it is also a radius. Thus, AD is also equal to 10 as the radius of the circle remains the same.
Using Pythagoras theorem, a^2 + b^2 = c^2, we can make a right angled triangle of ACD.
AC = 6 = a
CD = ? = b
AD = 10 = c
10^2 = 6^2 + b^2
b^2 = 10^2 - 6^2 = 64
b = CD = 8
Now, since Ar is the perpendicular bisector of chord BD, BD = CD x 2
BD = 8 x 2 = <u>16</u>
Looking at the info that is given it gives you the answer. If you were trying to find how much more he needs you need to know,
1: How much the music player is.
2: How much you already have.
3:How much you get each week.
So the answer would be C.
26+28=54 they are two consecutive even numbers? Hope this helps, sum is the addition of two numbers.
