One year, the population of a city was 160,000. Several years later it was 140,800. Find the percent decrease.

LekaFEV [45]

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 = $\frac{Difference}{Population} * 100$

Percent decrease = $\frac{19200}{160000}*100$

Percent decrease = 0.12 * 100

Percent decrease = 12%

Hence,

Percent decrease in population = 12%

Consider a rectangle whose length, L, is 4 more than twice its width, w. a. Write an expression for L in terms of w. b. Show tha

liq [111]

Answer:

Step-by-step explanation:

a)L=2w+4

b)P=2L+2w

sub L=2w+4,

P=2(2w+4)+2w

P=4w+8+2w

P=6w+8

c) 20=6w+8

12=6w

2=w

L=2(2)+4

Hence,

L=8 and w=2
