Answer:
Step-by-step explanation:
If the length of a bridge on a map is 1 cm,then the actual length = 40,000
If the length of a bridge on a map is 1.5 cm,then the actual length= 1.5 * 40000
= 60000.0 = 60,000 m
Density of population = total population / area of the township
Emerson township:
Population of Emerson = 6720 * (1/4)
= 1680
Density of population = 1680 /344
= 5 per square miles
Franco township:
30% of 1680 = 0.3 * 1680 = 504
Population = 1680 + 504
= 2184
Density = 2184/512
= 4 per square mile
Answer:
Step-by-step explanation:
1.you have to set up a proportion(x/120 = 20%/100%
2.you have to cross multiply
3.you have to divide 100x by the number you get
4.you got your answer.

helping me terror to hi how are u
Answer:
A = 22.5 m²
Step-by-step explanation:
longest side length
b = √((-7 + 4)² + (-1 - 8)²) = √90
other sides
a = √((-1 + 7)² + (2 + 1)²) = √45
height
h = √((√45)² - (½√90)²) = √22.5
Area of triangle
A = ½bh = ½√90√22.5 = 22.5 m²
a little math shows that this triangle is a tilted half of a square with sides √45
