A line adds up to equal 180 degrees. And adjacent angles also add to equal 180 since they share a side on a line. So add them together and make them equal 180
9x - 7 + 8.5x + 4 = 180
17.5x - 3 = 180
17.5x = 183
x = 10.5
Answer:
25 degrees
Step-by-step explanation:
40 + 50 = 90
2 x 25 = 5
Given:
circular merry-go-round that has a diameter of 15 feet.
Find: How much trim does he need to buy to put around the edge of the merry-go-round?
We need to find the circumference of the merry-go-round to get the measurement of the trim needed.
Circumference = π d
π = 3.14
d = diameter = 15 feet
Circumference = 3.14 * 15 feet
Circumference = 47.10 feet.
Mr. Osterhout needs to buy 47.10 feet of trim to put around the circular merry-go-round.
Based on your question that ask where each situation and the sampling frame doesn't match the population, resulting in under coverage. The possible answer to your question is , under coverage in a random sampling where the result that you get is still just a partial of the whole but it could be done in anytime as long as the number of people are still there. It means that the sampling result do not just base in one session of sampling.
