1. A car was bought in 2009 for $120 000. In 2010,its value decreased by 20%. In 2011, its valuedecreased by 10% of its value in 2010. Find thevalue of the car at the end of 2011.
Jawaban:
The value of the car at the end 2010 was:
(100% -20%)x $120 000

The value of the car at the end 2011 was:
(100%- 10%) x $96 000
= $86 400
2. The area of the floor is 138 m2. Work out the value of x.English in MathPlease help me to solve it
divide the floor into 2 rectangles. you'll get:
1. 8 . x
2. (15 - x) . 11
8 . x + 11(15 - x) = 138

5. When the value of a number is given, the significant figures provide an indication of theuncertainty in the value; for example, a value of 2.7 indicates that the number lies between2.65 and 2.75. Give ranges within which each of the following values lie.
design ......... ........
6. find the value of the unknown in each of the following figures
b). Besarnya sudut segitiga sama kaki 180°
maka,
<a + <b + <c = 180°
68° + 64° + 2b° = 180°
132° + 2b° = 180°
2b = 180° - 132°
2b = 48°
b = 24°
d). <ABC = 180°
maka,
<a + <b + <c = 180°
3d° + 4d° + d° = 180°
8d° = 180°
d = 180° / 8°
d = 22,5°
f).<ABC = 180°
maka,
<a + <b + <c = 180°
f° + f° + f° = 180°
3f° = 180°
f = 180°/3°
f = 60°

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
15. Find the value of x of absolute value in the following equation: | 4 - 3x | = | -4 |
|4 - 3x| = |-4| |4 - 3x| = 4 , , 4 - 3x = 4 -3x = 4 - 4 -3x = 0 x = 0 . . 4 - 3x = -4 -3x = - 4 - 4 -3x = -8 x = 8/3
16. find the value of b in the figure

20. Boleh bantu?? nnti ak bakal kasih 20 poin. Jawab ngasal? report. Every year, the value of a condominium in Singapore appreciates by 15% of its value in the previous year . If the value of the condominium was $899 300 in 2020, find its value in 2018.
Jawab:
in 2012 Condominium = $899300;
Rate, R = 15%
n = 2 because we have to calculate the value before 2 year from 2012 i.e. 2010;
By using the formula of n year ago value of principle;
;
= ;
By solving this we get the value of condominium in year 2010 is $ = 680000
