Answer:
72°
Step-by-step explanation:
Given that the radius(r) of the circle is 10 units and the length of arc ABC is 16π
The length of arc ABC = 
Where θ is the central angle in degrees.
Since the length of arc ABC is 16π,
The angle in a circle = 360°, therefore:
Central angle for arc AB (θ) = 360 - Central angle for arc ABC = 360 - 288 = 72°
Therefore the arc measure of arc AB is 72°

Answer:
17/12 or 1 and 5/12.
Step-by-step explanation:
3/4 and 2/3 needs to have the same denomenator. So, what number does both 4 and 3 go into? 12. So, 4x3=12, so we multiply the numerator by 3 too, to get 9 --> 9/12. Then, we see that 4x3=12 for 3 too so we multiply 2 by 4 which gets us 8 --> 8/12. So, now we add 9/12 + 8/12 to get 17/12, which then we make into a mixed number to get 1 and 5/12.
Answer: 52 people per bus
Step-by-step explanation:
The rescue organization saved 472 people.
Of this 472, 4 were saved by being air-lifted.
The rest went into buses.
The people in buses were:
= 472 - 4
= 468
They fit into 9 buses so the total per bus was:
= 468/9
= 52 people per bus
Since the difference between the numbers is 1.3 you just subtract 30.2-1.3 and get 28.9
