Answer:

25

Step-by-step explanation:

The angle of an arc is the same as the central angle. MarcCD is the same as the central angle COD which is given as 130o.

That means there are 50 degrees left for COA and DOA and because the chord and the diameter are equal, COA = DOA

That means that COA is 1/2 what is left over from 180 when 130 is subtracted from it.

1/2 * 50 = 25

The answer is A 25.

Find the power of 3/8^3
GREYUIT [131]

(3/8)³ = (3/8)(3/8)(3/8)

Multiply across:

(3/8) x (3/8) = 9/64

Simplify:

(9/64)(3/8) = 27/512

27/512 is your fraction answer (cannot be reduced).

To find the decimal answer, divide:

27/512 = 0.05

0.05 (rounded) is your decimal answer

hope this helps
