There are 85 seats in each section. 2125 divided by 25 is 85.
Answer:
27 I think just divide 81 by 3
1) 2a = 9b ⇒ 2:9
2) a + b = 3b ⇒ a = 2b ⇒ 1:2
Answers: 2:9 and 1:2
Answer:
Option (B)
Step-by-step explanation:
By the theorem of the inscribed angle,
"An angle inscribed in a circle measures half of the central angle subtended by the same arc."
Since m(arc XY) = 52°
Angle subtended by the the arc at the center (Central angle) = m∠XWY = 52°
Measure of inscribed angle = m∠XZY
By theorem, m∠XZY = 
m∠XZY = 
= 26°
Therefore, Option (B) will be the answer.
estimate = (40 * 50) / (4 * 5)
= 2000 / 20 = 100 (answer)
