5. The area of a rhombus is 90 cm2 . If the length of a diagonal is 18 cm, calculate the length of the other diagonal.
a = 1/2 x d1 x d2
90 cm2 = 1/2 x 18 cm x d2
90 cm2 = 9 cm x d2
90 cm2/9 cm = d2
d2 = 10 cm
Diketahui : Luas = 90cm^2 dan d1 = 18 cm
Luas Belah ketupat = (d1 x d2) / 2
90 = (18 x d2) / 2
90 = 9 x d2
10 = d2
Jadi, panjang digonal lainnya adalah 10 cm

7. A steel bar has length of 3 × 10² m, heated from 20°C to 120°C. If the length coefficient expansion is 1,2 × 10^-5 / °C and the length of steel to be affected by the first length, temperature changing and length linear coefficient expansion. Calculate the length of the end of the steel!
Materi: Pemuaian <<<<<<<<<Lo = 3 x 10² m
Δt = 120°C - 20°C = 100°C
α = 1,2 x 10⁻⁵/°C
Lt = ... ?
Problem solving:
Lt = Lo (1 + α x Δt)
Lt = 3 x 10² (1 + 1,2 x 10⁻⁵ x 100)
Lt = 3 x 10² (1 + 1,2 x 10⁻³)
Lt = 3 x 10² (1 + 0,0012)
Lt = (3 x 10²)(1,0012)
Lt = 300,36 m
8. The area of a square is 49 cm2. The area a rectangle is 19.9 cm2 greater than that of the square and its length is 12 cm. Find the breadth of the rectangle in cm,correct to 2 decimal places
[tex]A_{square} = 49 \ cm^2 \\ A_{rectangle} = (A_{square} + 19.9) \ cm^2 \\ A_{rectangle} = 68.9 \ cm^2 \\ L_{rectangle} = 12 \ cm \\ \\ A_{rectangle} = L_{rectangle} \times W_{rectangle} \\ W_{rectangle} = \frac{A_{rectangle}}{L_{rectangle}} \\ W_{rectangle} = \frac{68.9}{12} \\ W_{rectangle} = 5.74 \ cm[/tex]

11. Tony has a number with two decimal places . When it is rounded to the nearest tenth, the value is 8.5. Write down the smallest possible value of Tony’s number
When a number is rounded to the nearest tenth, it means that the number must be between the multiple of 0.1 before and after the number being rounded. In this case, 8.5 is the number that is rounded, and it is the multiple of 0.1. The smallest possible value of Tony's number is 8.45, which is 0.05 less than 8.5.

14. Calculate the length of metal in 60o C. if the length at 10o C is 5m! (CTE = 0,00006/o C)
SUHU DAN KALOR
▶ Pemuaian Panjang
L₀ = 5 m
α = 0,00006/°C
∆T = 60°C - 10°C = 50°C
Lₜ = __ ?
The length of metal in 60°C
Lₜ = L₀(1 + α ∆T)
Lₜ = 5(1 + 0,00006 × 50)
Lₜ = 5,003 m ✔

16. Correct your answer to2 decimal places.22 : 7 = ?
jawaban :
22 : 7 = 3,1429
penjelasan :• terlampir pada gambar ya
• 22 : 7 tidak habis dibagi
• pada gambar,saya menggunakan cara phytagoras
• ketika hasil pembagian tersebut panjang,anda bisa menyingkatnya
• kenapa pada jawaban ada 9 padahal dalam hasil tidak ada?karena di setelah 2 adalah 8 dan 8 adalah bilangan yang lebih dari lima,maka anda bisamenambahkan satu.

18. calculate the length of vector
Jawaban:
1. vektor a = 2i + 3j --- ( 2,3 )
• cari panjang vektor
|a| = √2² + 3²
|a| = √4 + 3
|a| = √13
panjang vektor a = √13
2. p = ( 1, -2 )
q = ( -2, 3 )
• Cari vektor pq
= q - p
= ( -2, 3 ) - ( 1 -2 )
= ( -3, 5 )
• panjang vektor
|pq| = √(-3)² + 5²
|pq| = √9 + 25
|pq| = √34
panjang pq = √34
19. calculate the time period of a simple pendulum of length 60 cm
A simple pendulum occurs when the angle between the deviation with vertical is small(θ ≈ 0 , sinθ ≈ θ , cosθ ≈ 1)
The period of pendulum
[tex]t = 2\pi \sqrt{ \frac{l}{g} } \\ \\ \: \: =2\pi \sqrt{\frac{ \frac{6}{10} }{10} } \\ \\ \: \: = 2\pi \sqrt{ \frac{6}{100} } \\ \\ \: \: = \frac{2\pi}{10} \sqrt{6} \\ \\ \: \: = \frac{\pi}{5} \sqrt{6} [/tex]
jika digunakan nilai π = 3,14... , maka :
