Question: The question is incomplete. The bicycle chain diagram wasn't attached to your question. Find attached of the diagram and the answer.
A bicycle chain is pulled tightly so that mn is a common tangent of the gears. Find the distance between the centers of the gears.
Answer: The distance between the centers of the gears is 17.8 in
Explanation:
From the attached file, using Pythagoras theorem to find the value of x, we have;
h = 4.3 - 1.8
= 2.5
x² = MN² + h²
x² = 17.6² +2.5²
x² = 309.76 + 6.25
x² = 316.01
x = √316.01
x = 17.8
Therefore, the distance between the centre of the gear is 17.8 in
Answer:
8
Explanation:
Gross domestic product is the market of all the goods and services produced and rendered during a specific period of time. GDP can be expressed in real value or nominal value .Real GDP does not include the inflation effect but the nominal GDP included the inflation effect on the value of product and services.
According to given data in the question
Real GDP per capita in 1950 = $6,000
Real GDP per capita in 2009 = $48,000
Increase in time = Real GDP per capita in 2009 / Real GDP per capita in 1950 = $48,000 / $6,000 = 8 times

answer
The decision to build the park or not would be based solely
on the cost – benefit relationship of this project. Since there is no other
factor considered in this problem, you only need to see if the benefit of
constructing the park would exceed its cost. In this problem, the cost to
construct the park is $20,000 while the marginal benefit would be $24,000
($8,000 x 3 families that can benefit from this project). Therefore, you can
say that the benefit has exceeded its cost. As a conclusion, the neighborhood
park should be built because it benefits the families living in that area more
than its cost.
