Answer:
Percent decrease in population = 12%
Step-by-step explanation:
Given that:
Population of city = 160,000
Population of city after several years = 140,800
Difference= 160000 - 140800 = 19200
Percent decrease =
Percent decrease =
Percent decrease = 0.12 * 100
Percent decrease = 12%
Hence,
Percent decrease in population = 12%
Radius = 5 units
Height = 10 units
Volume = 785.4 units
It would be the first one because if you do 4^2+4^2 it does NOT equal 32 it equals a even greater number. So the first one is not a right triangle
Answer:
29 feet above sea level
Step-by-step explanation:
One floor is 9 feet high, so the top of the first floor will be 9 feet above the ground.
The ground is also 20 feet above sea level, so add 9 to this to find how many feet above sea level the top of the first floor is:
20 + 9
= 29 feet above sea level
