1. the cell shown in the diagram has been magnified 3000 times. the diagram is 21 mm wide. what is the actual diameter of the cell?
The actual diameter of the cell based on the question above is 21/3000 mm or 0,007 mm. Setelah diperbesar sebanyak 3000 kali dan didapati ukuran diameter dari sell tersebut adalah 21 mm maka untuk menegtahui ukuran sebenarnya dari sell tersebut adalah dengan membagi ukuran setelah diperbesar dengan jumlah kali perbesaran. Oleh karena itu, didapati ukuranyya adalah 0,007 mm.
Pembahasan:
Sel adalah kumpulan dari materi yang paling sederhana yang hidup dan bagian penyusun makhluk hidup. Sel dapat melakukan aktivitas kehidupan dan reaksi kimia dalam mempertahankan kehidupan di dalam sellnya. struktur sel antara stuktur sel hewan dan tumbuhan berbeda beda. Struktur sel terdapat dua jenis yaitu struktur sel prokariot dan sel wukariot. Struktur sel prokariot adalah struktur sell yang tidak memiliki neukleus.sedangkan sel eukariot adalah struktur sel yang memiliki neukleus.Semua sel makhluk hidup memiliki membran plasma atau membran sel. Membran sel adalah lapisan paling luar yang melapisi dan menjaga komponen sel yang ada di dalamnya.Dinding sel adalah bagian sel yang hanya dimiliki oleh tumbuhan dan jamur. Pitoplasma memiliki 3 bagian utama yaitu: neukleus atau inti sel, sitoplasma, dan sitoskeleton.Pelajari lalebih lanjut

2. The actual distance between Town P and Town Q is 120 km whereas the distance on a man is 15 cm . Calculate the actual length , in km . of a river measuring 7 cm on a map .
Penjelasan dengan langkah-langkah:
skala = jarak peta : jarak sebenarnya
= 15 cm : 120 km
= 15 cm : 120000
= 1 : 8000
jarak sungai dalam peta = 7 cm
maka
jarak sesungguhnya = 7 x skala
= 7 x 8000
= 56000 cm
= 56 km
3. Calculate the concentration in mol/dm3
1. 500 cm³ = 0,5 dm³
= 1 mol/0,5 dm³ = 2 mol/dm³
2. 1000 cm³ = 1 dm³
= 0,2 mol/ 1 dm³ = 0,2 mol/dm³
3. 100 cm³ = 0,1 dm³
= 0,1 mol/0,1 dm³ = 1 mol/dm³
4. Mr NaOH: 40
mol NaOH: 0,8 gr/40 = 0,02 mol

9. The scale on a map is 1 : 20 000. The area of a lake on the map is 1.6 square centimeters. Calculate the actual area of the lake. Give your answer in square metres.
Scale = area on the map/ actual area
1/20.000 = 1,6 / actual area
Actual area = 1,6 × 20.000 = 32.000 square centimeters
= 3,2 square meters.actual area= scale × area on the map
= 20.000 × 1.6 cm2
=20.000 × 16/10
20.000 ÷ 10 × 16
= 32.000 cm2
= 3.2 meter2

12. calculate the surface area,in cm²,of the wood
aku jawab pake bahasa indonesia aja ya
cari sisi miring dulu
= √15² + 8²
=√289
= 17 cm
luas permukaan
= 2x luas alas + keliling . Tinggi prisma
= ( 2 . 1/2 . 15 . 8) +[(15 + 8 + 17) . 20]
= 120 + 800
= 920 cm2
Hypotenuse = √15² + 8²
= √225 + 64
= √289
= 17 cm
surface area :
circumference of the base x tall + 2 x broad base
= (17 + 15 + 8) x 20 + 2 x (15 x 8 x 1/2)
= 40 x 20 + 2 x (15 x 4)
= 800 + 2 x 60
= 800 + 120
= 920 cm²

18. A glass house is in the shape as shown in the figure . calculate total area of glass needed and calculate the volume of the glass house
Jawab:
Total Luas seluruh bangunan = L prisma segitiga + L balok
= 248 m² + 292 m² = 540 m²
Total Volume seluruh bangunan = V prisma segitiga + V balok
= 60 m³ + 336 m³ = 396 m³
Penjelasan dengan langkah-langkah:
Bangunan ini adalah gabungan dari prisma segitiga dan balok.
Diketahui :
Prisma segitiga : alas = 5 m
tinggi alas = 6 m
tinggi prisma = 11 m - 7 m = 4 m
Ditanya : L = ?
V = ?
L = 2 X Luas alas + Keliling alas + tinggi
= 2 X (1/2 X 5X6) + (5+5+6) x 4
= 2 x (15 + 16 x 4)
= 2 x 124 = 248 m²
Volume = Luas alas X tinggi
= (1/2 X 5X6) X 4
= 60 m³
Sekarang kita hitung balok.
Diketahui : p = 8 m
l = 6 m
t = 7 m
Ditanya : L = ?
V = ?
L balok = 2 (pl + pt + lt)
= 2 (8X6 + 8X7 + 6X7)
= 2 (48+56+42)
= 2 x 146 = 292 m²
Volume balok = pxlxt
= 8 X 6 X 7
= 336 m³
Total Luas seluruh bangunan = L prisma segitiga + L balok
= 248 m² + 292 m² = 540 m²
Total Volume seluruh bangunan = V prisma segitiga + V balok
= 60 m³ + 336 m³ = 396 m³
