Answer:
35.3 years
Step-by-step explanation:
Given :
In 1980 the median age of a resident of the united state was 30 years.
By 2000 the median age had increased 5.3 years.
Solution :
The median age the median age of a resident of the united state = 30 years
Since the median age had increased 5.3 years in 2000
Thus , the median age of a resident of the United States in year 2000 = 30+5.3 = 35.3 years
Hence the median age of a resident of the United States in year 2000=35.3 years
2/3 or 0.6 repeating is the answer
The wingspan is 36 m.
Using a proportion to solve this, we write the scale factor as a ratio first: 19/38, since 19 is the size of the model's length and 38 is the real length. For the second ratio, we have 18 for the size of the model wingspan and x for the real wingspan:
19/38 = 18/x
Cross multiply:
19*x = 38*18
19x = 684
Divide both sides by 19:
19x/19 = 684/19
x = 36 m
