2. What is the area of the triangle shown below
a = 5
b = 5
c = 8
Keliling
= a + b + c
= 5 + 5 + 8
= 18
s = 1/2 x keliling
s = 1/2 x 18
s = 9
Luas
= √(s(s - a)(s - b)(s - c))
= √(9(9 - 5)(9 - 5)(9 - 8))
= √(9 x 4 x 4 x 1)
= √144
= 12 satuan luas
3. what is the area of the rectangle shown below?
Jawab:
Penjelasan dengan langkah-langkah:
The area= luas yaa
okee berarti sangat gampang kpk!
Luas persegi panjang= lebar x panjang
maka panjang= 5 3/4 =23/4 cm dan lebar=3 cm
L= pxl
= 23/4 x 3
=69/4
=17 1/4 cm atau 17,25 cm
4. choose which one of the choice below is insert
Jawaban:
mohon maaf tidak ada pilihan lain

the correct equation if electrolyte ionization reaction in water is H2 + O2 = H2O.
9. What is the value of n in the equation 64 ÷ n = 8
Jawaban:
[tex]64 \div n = 8[/tex]
[tex] \frac{64}{n} = 8[/tex]
[tex]64 = 8n[/tex]
[tex]8n = 64[/tex]
[tex]8n \div 8 = 64 \div 8[/tex]
[tex]n = 8[/tex]

10. A figure is made up of a rectangle and a semicircle as shown in the diagram below. what is the area of the figure?
Jawab:
Area itu bahasa inggris dari Luas, maka
Area of square = S x S
= 7 x 7
= 49 cm²
Radius = Diameter / 2
= 7 / 2
= 3.5 cm
Area of [tex]\frac{1}{2}[/tex] circle = [tex]\frac{1}{2}[/tex] x [tex]\pi[/tex] x r²
= [tex]\frac{1}{2}[/tex] x [tex]\frac{22}{7}[/tex] x 3.5²
= 19.25 cm²
Are of the figure = 49 + 19.25 = 68.25 cm²
Penjelasan:
phi [tex](\pi )[/tex] untuk [tex]\frac{22}{7}[/tex] digunakan apabila jari-jari/radius berkelipatan 7, sedangkan
phi untuk 3.14 digunakan apabila jari-jari/radius tidak berkelipatan 7
11. 1) What is the y-intercept of the quadratic equation below? * y = x2 - 6x + 9
Penjelasan dengan langkah-langkah:
titik potong persamaan kuadrat
y = x² - 6x + 9
- titik potong terhadap sumbu y, x = 0
y = 0² + 6(0) + 9
y = 9
titik potongnya (0, 9)
- titik potong terhadap sumbu x, y = 0
x² - 6x + 9 = 0
(x - 3)(x - 3) = 0
x = 3
titik potongnya (3, 0)
12. What is the area of the right triangle shown below
ANSWER:
60.
Penjelasanya :
(theorema phytagoras) a=[tex]\sqrt{b^{2} -c^{2} }[/tex]
a= 17[tex]\sqrt{17^{2}-8^{2} } = \sqrt{289-64}[/tex]
a=[tex]\sqrt{225} =[/tex]15
(the area of the right triangle) :
1/2 x a x h
1/2 x 8 x 15
= 60
ur welcome:)
