2. A pot contained twice as much water as a bottle. The total amount of water in both the pot and the bottle was 5 l. What was the amount of the water in the bottle?
Jawaban:
5/3litersofwater
Penjelasan dengan langkah-langkah:
pot = 2 × bottle
pot + bottle = 5 liters
substitute pot with x and bottle with y.
x = 2y
x + y = 5
substitute x with 2y into the equation.
x + y = 5
2y + y = 5
3y = 5
y = 5/3liters
theamountofwaterinsidethebottlewas5/3liters.
x = 2y
x = 2(5/3)
x = 10/3
theamountofwaterinsidethepotwas10/3liters.

5. 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

13. A flask contained 4 times as much water as a jug at first. After 1.05 l ofwater were poured from the flask into the jug, both containers had thesame amount of water. How many litres of water are there in the jug now?
Jawab:
The water there in the jug now are 1,75 L.
Penjelasan dengan langkah-langkah:
Imagine:
Flask = F
Jug = J
F = 4J
F - 1,05 = J + 1,05
Substitution:
F - 1,05 = J + 1,05
4J - 1,05 = J + 1,05
4J - J = 1,05 + 1,05
3J = 2,10
J = [tex]\frac{2,10}{3}[/tex]
J = 0,70 L
F = 4J
F = 4 X 0,7
F = 2,80 L
Jug now:
0,70 L + 1,05 L = 1,75 L

15. 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

20. A container consists of a cylinder of diameter 1.4 m and an inverted cone. The height of the container is 3.6 m and it contains water to a depth of 3 m, as shown below. Given that the volume of the water in the container is 2464 litres, find the height of the cylinder. (Take π 22/7)
Diketahui :
r = 0,7 m = 7 dm
tinggi tangki = 3,6 m = 36 dm
Diasumsikan :
tₖ = tinggi kerucut
tₜ = tinggi tabung
tinggi tangki = tinggi kerucut + tinggi tabung
36 = tₖ + tₜ --> ( i )
Volume air pada kerucut = ⅓πr²tₖ
Volume air pada tabung = πr²tₜ
Volume air = 2.464 liter
Volume air pada kerucut + volume air pada tabung = volume air
⅓πr²tₖ + πr²tₜ = 2.464
πr².( ⅓tₖ + tₜ ) = 2.464
(22/7).(7)².( ⅓tₖ + [30 - tₖ] ) = 2.464
154.( -⅔tₖ + 30 ) = 2.464
( -⅔tₖ + 30 ) = 2.464 ÷ 154
-⅔tₖ + 30 = 16
-⅔tₖ = 16 - 30
-⅔tₖ = -14
tₖ = -14 ÷ [-⅔]
tₖ = 21
Masukkan nilai tₖ pada ( i ) :
36 = tₖ + tₜ
tₜ = 36 - tₖ
tₜ = 36 - 21
tₜ = 15
Maka, tinggi tabung adalah 15 dm = 1,5 m
