2. An alloy of silver and gold weight 15 ounces in air and 14 ounces in water. Assumming that silver loses 1/10 of its weight in water and that gold loses 1/19 of its weight, how many ounces of each metal are in the alloy?
Jawab:
the weight of each metal is
gold = 10 ⁵ / ₉ounce
silver = 4 ⁴ / ₉ ounce
Penjelasan soal:
Soal tersebut menjelaskan bahwa
Terdapat campuran emas dan logamJika di udara 15 ons di air 14 onsJika di air emas kehilangan ¹/₁₉ beratnya dan perak kehilangan ¹/₁₀ beratnyaPembahasan soal:
karena berat asli campuran logam tersebut adalah 15 ons, maka dapat ditulis dengan
[tex]\boxed {emas \ + \ perak \ = \ 15 \ ons}[/tex]
Lalu saya misalkan,
emas = a
perak = b
[tex]\boxed { a+b = 15 }[/tex]
di sini saya akan menggunakan metode eliminasi
a+b = 15
lalu kita masukkan persamaan tersebut menjadi
[tex]\frac{19-1}{19} a + \frac{10-1}{10} = 14\\\\\ \frac{18}{19}a + \frac{9}{10}b = 14 ---> (\times 190) \\\\\frac{18 \times 190}{19} a + \frac{9 \times 190}{10} b = 14 \times 190\\\\\ 180a+171b = 2660[/tex]
lalu kita samakan vaiabel a agar dapat di eliminasi
a+b = 15 ---> ( ×180)
180a + 180b = 2700
Maka,
180a + 180b = 2700
180a + 171b = 2660
_________________ -
9b = 40
b = 40/9
b = 4 ⁴/₉ ons
a = 15 - 4 ⁴/₉
a = 10 ⁵/₉ gram

6. how many ounces of pure silver must be added to 36 oz kf 60% pure silver to make an alloy that is 76% pure silver?
36 ounce → 60% pure
x → 76% pure
x = 36 x 76 / 60 = 45,6 ounce
You need to add 45,6 - 36 = 9,6 ounce of pure silver.
7. a car can travel 288 miles on 18gallons of gasoline. how can it travel on 24 gallons
Jawaban:
Can.
Penjelasan dengan langkah-langkah:
that problem can be solve with;
comparisons that have the same value ( perbandingan senilai )
288mil = 18 gallons of gasoline
........mil = 24 gallons of gasoline
The formula of same value comparisons is
a1/b2=b1/b2
= 288/b2=18/24
(18×b=288×24)
18b = 6912
b = 6912/18
= 384 miles
So, the car can cover 384 miles on 24 gallons of gasoline.
I hope this can help you..

11. 30ton=...ouncesbeserta caranya
Jawaban:
30 ton = 30 x 1000 = 30.000 kg
30.000 kg = 30.000 x 10 = 300.000 ons
atau
1 ton = 1.000 kg
1 kg = 10 ons
maka 1 ton = 1.000 x 10 = 10.000
jadi 30 ton = 30 x 10.000 = 300.000 ons

Jika perak kehilangan 1/10 beratnya di air, dan emas 1/19 dari beratnya, berapa ons masing-masing logam di campuran tersebut?
Jawab:
Penjelasan dengan langkah-langkah:
Let original length = x and
Original breadth = y
Original area = xy
New lenght = ˣ/₂
New breadth = 3y
New area = (ˣ/₂ × 3y) = ³/₂ xy
∴ Increate % = ¹/₂ xy × 1/xy × 100
= 50%

20. A house painting company has 8 1/4 gallons of paint available to paint available to paint a house. the paint will be divided equally among 3 painters. how many gallons of paint will each painter receive?.....
I think so..
8 1/4 : 3
= 33/4 :3
= 2.75 atau 2 3/4
so, Many gallons of paint will each painter receive is 2 3/4 ..
8 * 1/4 = 8/4 = 2 gallons There are 3 painters so each painter will get 1/3*2 gallons = 2/3 of a gallon per painter... So, 2/3 of gallon per painter... Thank you :D
