In 1980 , the population of an island was 1.800.000. In 2008 , the population was 1.600.000 . Find the percent decrease in population !
1. In 1980 , the population of an island was 1.800.000. In 2008 , the population was 1.600.000 . Find the percent decrease in population !
1.800.000 - 1.600.000 = 200.000
x/100 × 1.800.000 = 200.000
X × 1.800.000 = 200.000 × 100
X × 1.800.000 = 200.000.000
X = 200.000.000 ÷ 1.800.000
x = +/- 11%
2. The population of a city was 2 million in 2017 and 2.1 million in 2018. Assuming the growth rate of the population remains the same per year, estimate the population in a) 2019
Jawab:
Penjelasan dengan langkah-langkah:
If the growth rate of the population remains the same per year, we can use the formula:
P = P0 * (1 + r)^n
where P is the population after n years, P0 is the initial population, r is the growth rate, and n is the number of years.
We can find the growth rate by dividing the increase in population between 2017 and 2018 by the initial population in 2017:
r = (2.1 million - 2 million) / 2 million = 0.05
So, the formula becomes:
P = 2 million * (1 + 0.05)^n
For 2019:
n = 2 (2018 is the second year)
P = 2 million * (1 + 0.05)^2 = 2 million * 1.1025 = 2.205 million
Therefore, the estimated population in 2019 is 2.205 million

Penjelasan dengan langkah-langkahMateri
Perbandingan adalah membandingkan dua nilai atau lebih dari besaran yang sejenis dan ditunjukkan dengan nilai yang paling sederhana.
Perbandingan yang dapat terjadi pada data populasi adalah perbandingan persentase populasi penduduk di suatu wilayah dari wilayah keseluruhan atau daerah yang melingkupi.
Diketahui
Banyak populasi masyarakat Banten = 25 persen dari populasi penduduk pulau Jawa.Penduduk pulau Jawa menempati 15 persen dari populasi di Indonesia.Ditanya
Berapa persenpenduduk pulau Jawa di Indonesia?
Jawab
Berikut bentuk matematis permasalahan di atas.
Misalkan,
B = Jumlah Penduduk Banten
J = Jumlah penduduk pulau Jawa
I = Jumlah penduduk Indonesia
Maka,
B = 25% dari J
J = 15% dari I
[tex]\frac{B}{J} = \frac{25}{100}[/tex]
[tex]\frac{B}{I} = \frac{15}{100}[/tex]
Untuk mendapatkan persentase penduduk pulau Jawa di Indonesia, maka ditentukan perbandingan [tex]\frac{J}{I}[/tex].
[tex]\frac{B}{J} \times \frac{I}{B} = \frac{25}{100} \times \frac{100}{15}[/tex]
[tex]\frac{I}{J} = \frac{25}{15}[/tex]
[tex]\frac{J}{I} = \frac{15}{25}[/tex]
[tex]\frac{J}{I} = \frac{15 \times 4}{25 \times 4}[/tex]
[tex]\frac{J}{I} = \frac{60}{100}[/tex]
[tex]\frac{J}{I} = 60[/tex]%
Dengan demikian, penduduk yang tinggal di pulau Jawa adalah 60% dari seluruh penduduk di wilayah Indonesia.

PembahasanUn+2 - Un = m un-1
u2015 - u2013 = m u2014
41 - 20 = m u2014
m u2014 = 21
u2014 - u2012 = m u2013
[tex]\frac{21}{m}[/tex] - 13 = 20m
21 - 13m = 20[tex]m^{2}[/tex]
20[tex]m^{2}[/tex] + 13m - 21 = 0
(4m - 3)(5m + 7) = 0
m = [tex]\frac{3}{4}[/tex]

11. The present population of a certain city is 66,550. If 3 years ago, the population of the city was 50,000, find the annual population growth rate.
Jawaban:
To find the annual population growth rate, we need to determine the difference in population between the current population and the population 3 years ago, and divide that number by the number of years that have passed. Then, we need to divide that number by the initial population and multiply by 100% to express the result as a percentage.
The difference in population between the current population and the population 3 years ago is 66,550 - 50,000 = 16,550.
The annual population growth rate is (16,550 / 3) / 50,000 * 100% = 5.5%. This means that the population of the city is increasing by 5.5% per year.

14. Every year, the value of an antique vase appreciates by 20% of its value in the previous year. If the value of the vase was $180 000 in 2012, find its value 2010.
Jawab:
$125.000
Penjelasan dengan langkah-langkah:
harganya naik setiap tahun, jadi kalau tahunnya berkurang harganya turun/lebih rendah. the price decreased.
in 2012 = $180.000, interest 20%
so in 2010 =
price 2012 = (1 + interest)² x price 2010 -> 2 because it was 2 years apart
$180.000 = (1 + 0,2)²x price 2010
$180.000 = 1,2² x price 2010
price 2010 = $125.000
