Answer:
36
Step-by-step explanation:
Set up as proportion 40/100 = x/90
Cross multiply 3600 = 100x
DIvide by 100
x = 36
Answer:
x^2 + 4x - 5
Step-by-step explanation:
We need to simplify this
xx - 1 * x +5x - 5 * 1
Simplify further
x^2 + 4x - 5
Thus, we have our answer
We know that
scale factor=measure larger triangle/measure smaller triangle---->18/12
scale factor=1.5
so
measure larger triangle=scale factor*measure smaller triangle
for the leg in the smaller triangle equal to 5
measure larger triangle=1.5*5-----> 7.5
the answer is
7.5
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%
