find the value of each of the following 0.8% of 4.5m​

1. find the value of each of the following 0.8% of 4.5m​

Jawab:

we can use the formula:

percentage/100 x value = result

So, for this case:

0.8/100 x 4,500,000 = 36,000

Therefore, 0.8% of 4.5 million is equal to 36,000.

3. find the hcf of each of the following 15,60 dan 75​

Jawaban:

The prime factorisation of 60 and 75 are :60 = 2 × 2 × 3 × 575 = 3 × 5 × 5So, HCF = 3 × 5 = 15LCM = 2×2×3×5×5 = 300Now, we will calculate HCF by Euclid's Division algorithm.75 = 60 × 1 + 1560 = 15 × 4 + 0Since the last divisor is 15, hence HCF75,60 = 15LCM75,60 = 60 × 75HCF75,60 = 60 × 7515 = 300

5. For each of the following figures, find the area of the blue region(s).​

c. 45 cm²

d. 150,96 cm²

Penjelasan dengan langkah-langkah:

c. L = L.trapesium - L.segitiga

= 1/2 x (9+17) x 12 - 1/2 x 17 x 6

= 1/2 x 16 x 12 - 51

= 96 - 51

= 45 cm²

d. L = L.jajaran genjang - L.lingkaran

= 12 x 22 - 3,14 x 6 x 6

= 264 - 113,04

= 150,96 cm²

6. Find the value of the unknown in each of the following figure

180 = 8a
22,5 = a
2a = 45
3a = 67,5

A = 45
B = 67,5
C = 67,5

7. For each of the following figure, find the value of c

Penjelasan dengan langkah-langkah:

16 c = 180°

c = 180°/16

c = 11,25°

16c° = 180°

c° = 180° ÷ 16

= 11,25°

11. The circular portions of the following figures are semicircles. Find the perimeter and area of each of the following figures. ​

Penjelasan dengan langkah-langkah:

(a)

Luas = 3x5/2 + 3,14 x 2²/2 = 7,5 + 6,28 = 13,78 m²

Keliling = 3+5 + 3,14x2 = 8 + 6,28 = 14,28 m

(b) Luas = 3,14 x 9/2 + 3,14 x 4,5

= 3,14 x 9 = 28,26 cm²

Keliling = 3,14 x 18/2 + 3,14 x 9

= 3,14 x 18

= 56,52 cm

Penjelasan dengan langkah-langkah:

a.

Luas = 3 × 5/2 + 3,14 × 2²/2 = 7,5 + 6,28 = 13,78 m²

keliling = 3 + 5 + 3,14 × 2 = 8 + 6,28 = 14,28 m

b.

Luas = 3,14 × 9/2 + 3,14 × 4,5 = 3,14 × 9 = 28,26 m²

keliling = 3,14 × 18/2 + 3,14 × 9 = 3,14 × 18 = 56,52 cm

12. find the value of the unknown in each of the following figures. plis help part b.​

Jawab:

sudut A = 108°

Sudut B = 144°

Penjelasan dengan langkah-langkah:

Rumus menghitung Jumlah derajat dari sudut bangunan

(n-2) x 180°

dengan n = jumlah sisi

diketahui gambar tersebut merupakan heksagon (6 sisi)

berarti jumlah sudutnya adalah (6-2) x 180 = 4 x 180 = 720°

122 + 128 + 114 + 104 + 3b + 4b = 720

468 + 7b = 720

7b = 252

b = 36

maka sudut A = 3 x (36) = 108°

sudut B = 4 x (36) = 144°

16. Given that o is the centre of each of the followingcircles, find the values of the unknowns.​

Penjelasan dengan langkah-langkah:

C² = 17²-13²

= 289 -169

17. find the value of x and y in each of the following​

a + x = 360°

a = 360° – x

 ‏‏‎ 

a + 31° + 31° = 180°

(360° – x) + 62° = 180°

360° + 62° – 180° = x

242° = x

x = 242°

 ‏‏‎ 

68° + (y + 31°) + (y + 31°) = 180°

2(y + 31°) = 180° – 62° = 118°

[tex]y + 3 {1}^{0} = \frac{11 {8}^{0} }{2} = 5 {6}^{0} [/tex]

y = 56° – 31°

y = 25°

18. Find the perimeter and the area of each of the following shaded regions!

Jawab:

Penjelasan dengan langkah-langkah:

Perimeter : keliling

a.

P =60/360 x 2πR

=60/360 x 2x22/7x42

= 44 cm

Area = 60/360 x πR²

        = 60/360 x 22/7 x 42²

        = 924 cm²

b.

P1 =  1/4x2πR1  + 1/4x2πR2 + 2x(R1-R2)

    = 1/4x2π( R1+R2) +  2x(R1-R2)

    = 1/2x22/7x(18-12) + 2(18-12)

    =44/7 + 8

    = 44/7 + 56/7

    = 100/7

    = 14,3 cm

Area  = 1/4xπ( R1²- R2²)

         = 1/4x22/7x(18²-12²)

         = 22/28 x (324-144)

         = 22/28 x 180

         = 141,4 cm²

20. 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,
