1. 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

14. To reduce 16 ounces of a 25% solution of antiseptic to a 10% antiseptic solution, how much distilled water should a nurse add? 36 oz 12 oz 24 oz
Jawaban:
Let x = amt of distilled water
:
A simple equation
.25(16) = .10(x+16)
4 = .10x + 1.6
4 - 1.6 = .1x
2.4 = .1x
x = 2.4/0.1
x = 24 oz of distilled water
:
:
Prove this by seeing the amt of antiseptic is the same (only the % changes)
.25(16) = .10(24+16)
4 = .1(40)

19. 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

You need to add 45,6 - 36 = 9,6 ounce of pure silver.
20. 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
