2. 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
3. On a map the distance of 20 kilometers was represented by a length of 80 cm the scale of a map was 1 : n calculate the value of n
Jawaban:
20 km = 2.000.000 cm (multiply by 100.000)
MD = map distance
S = scale
AD = actual distance
[tex] \sf \: MD = S \times AD \\ \\ \sf \:80 = \frac{1}{n} \times 2.000.000 \\ \\ \sf \:80 = \frac{2.000.000}{n} \\ \\ \sf \:80n = 2.000.000 \\ \\ \sf \:n = \frac{2.000.000}{80} \\ \\ \sf \:n = 25.000[/tex]
The value of n is 25000

10. The radius of a bicycle wheel is 50 cm. If the bicycle rolls 10 complete turns, the bicycle travels ... m. (Take p=3.14 .)
Answer:
31,4 m
is known:
-> r = 50 cm
-> d = 2 × r = 2 × 50 = 100 cm
