Answer:
NA
a = 53
Step-by-step explanation:
A bisector creates two equal angles. Set them equal to each other.
5a - 160 = 2a - 1 ( subtract 2a from both sides)
3a = 159 (add 159 to both sides)
a = 53 (divide by 3)
Answer:
15.7 inches
Step-by-step explanation:
A clock is a circle . It tells us that the radius of the circle is 2.5 inches, and it is asking for the circumference. Therefore, we can use the equations for a circle to solve for the circumference.

Answer:
r = - 
Step-by-step explanation:
The n th term of a GP is
= a₁ 
where a₁ is the first term and r the common ratio
Here a₁ = 18 and a₆ = -
, then
18
= -
( divide both sides by 18 )
= -
( take the fifth root of both sides )
r =
= - 
Answer: P(not shaded sector) = 0.50
Step-by-step explanation:
Since we have given that
Number of shaded parts = 6
Number of unshaded parts = 6
Total parts = 6+6 = 12
So, Probability of getting not shaded sector is given by

Hence, P(not shaded sector) = 0.50
