2. Find the equivalent fractions.⅔ = ….. = …..⅕ = ….. = …..Which one is the greater fraction?¾ or ⅙ The greater is …..⅖ or ½ The greater is …..Which one is the smaller fraction?⅔ or ⅚ The smaller is …..3/7 or ½ The smaller is …..
Jawab:
Penjelasan dengan langkah-langkah:
⅔ = 4/6 = 8/12
⅕ = 2/10 = 4/20
3/4 = 3 : 4 = 0,75
1/6 = 1 : 6 = 0,16
So , 3/4 is the greatest.
2/5 = 2 : 5 = 0,4
1/2 = 1 : 2 = 0,5
So, 1/2 is the greatest.
2/3 = 2 : 3 = 0,66
5/6 = 5 : 6 = 0,83
So, 2/3 is the smallest.
3/7 = 0,42
1/2 = 0,5
3/7 is the smaller
3. A basket with 65 sweets has a mass of 3200 g The same basket with40 sweets has a mass of 2125 g Each sweet has the same massWhat is the mass of the basket?tolong
Jawaban:
405 g
Penjelasan:
If the mass of each sweet is M and the mass of the basket is B, then you have two equations in two unknowns that can be solved as linear equations.
65M + B = 3200
40M + B = 2125
Subtract the second equation from the first one to get:
25M = 1075
M = 1075 / 25
M = 43
Substitute the value of M into the first equation to get:
65M + B = 3200
65(43) + B = 3200
2795 + B = 3200
B = 405
Check by putting both values into the second equation:
40(43) + 405 = 2125
1720 + 405 = 2125?
2125 = 2125
Correct

4. Which is greater?17¹⁷ or 33¹⁶
Answer:
17¹⁷=8,2724…×10²⁰
33¹⁶=4,3046…×10²³
----------------------------------------
Because 10²⁰ is smaller than 10²³ so the conclusion is 33¹⁶ is greater than 17¹⁷

5. A bag contains 15 potatoes which have a mean mass of 136 g,The farmer puts 3 potatoes which have a mean mass of 130 g into the bag.Calculate the mean mass of all the potatoes in the bag.
x = n1x1 + n2x2 / n1+ n2
= 15.136 + 3.130 / 15+3

9. A bag of grapes has a mass of 4.55 kg. A bag of mangoes has a mass of16.90 kg. What is the total mass of the two bags of fruits?
Jawaban:
total mass = grapes mass + mangoes mass
total mass = 4.55 kg + 6.90 kg
total mass = 11.45 kg
10. When a box contains 50 identical balls, it has a mass of 13.9 kg. The empty box has a mass of 400 g. Find the mass of each ball in kilograms.
mass of 50 balls = 13.9kg - 400g
= 13.9kg - 0,4kg
= 13.5kg
mass of each ball = 13.5kg/50
= 0.27kgKetika sebuah kotak berisi 50 bola yang sama, beratnya 13,9 kg. Kotak kosong itu beratnya 400 g. Temukan berat dari masing-masing bola dlam kg.
Dik:
Jumlah bola 50 bola
Berat total 13,9 kg
Berat kotak kosong 400 g = 0,4 kg
Berat bola keseluruhan = berat total - berat kotak kosong
= 13,9 kg - 0,4 kg = 13,5 kg
Berat masing-masing bola = berat bola keseluruhan : jumlah bola
= 13,5 kg : 50 bola = 0,27 kg/bola
Jadi berat masing-masing bola = 0,27 kg/bola
Translatenya:
Clue,
Numbers of balls = 50 balls
Total mass = 13,9 kg
Mass of empty box = 400 g = 0,4 kg
Total mass of balls = total mass - mass of empty box
= 13,9 kg - 0,4 kg
Mass of each ball = total mass of balls : numbers of balls
= 13,5 kg : 50 balls = 0,27 kg/balls
So the mass of each ball = 0,27 kg/balls

15. Ethanamide is a solid at room temperature. 1-Aminobutane, which has about the same molecular mass, is a liquid. Explain.
Kelas: XI
Mata Pelajaran: Kimia
Materi: Titik Didih Senyawa
Kata Kunci: Etanamida, 1-Aminobutane
Jawaban pendek:
Etanamida padat pada suhu kamar 1-Aminobutane, yang memiliki massa molekul yang sama, adalah cairan.
Hal ini karena polaritas Etanamida yang lebih besar, akibat adanya gugus =O yang bermjatan negatif dan gugus -NH₂ yang bermuatan positif di strukturnya, sehingga tarikan antar molekulnya lebih besar dan perlu lebih banyak energi kalor untuk memecah ikatan ini dan membuatnya menjadi cair. Sementara 1-Aminobutane tidak memiliki gugus =O ini.
Jawaban panjang:
Etanamida atau asetamida (CH₃CONH₂) memiliki struktur:
O
||
CH₃ – C – NH₂
Titik leleh Etanamida tinggi untuk ukuran molekulnya yang relatif kecil, sebesar 79 hingga 81 °C, dan berbentuk padat pada suhu ruang (sekitar 25 °C).
Hal ini karena Etanamida memiliki tarikan polar antara molekulnya. Atom hidrogen dalam gugus -NH2 dalam asetamida cukup positif untuk membentuk ikatan hidrogen dengan pasangan tunggal pada atom oksigen di gugus =O, dari molekul asetamida lain.
Semakin besar tarikan antara molekulnya, akan membuat perlu lebih banyak energi kalor untuk memecah ikatan ini dan membuatnya mengalami perubahan fase (meleleh atau menguap), yang menyebabkan tingginya titik leleh Etanamida.
1-Aminobutane (CH₃(CH₂)₃NH₂) memiliki struktur:
CH₃ – CH2 – CH2 – CH2 – NH₂
Di sini terlihat bahwa 1-Aminobutane tidak memiliki gugus =O yang ada dalam Etanamida. Akibatnya, tidak ada daya tarik yang antara molekul 1-Aminobutane, dan akibatnya titik didihnya juga rendah. Titik didih 1-Aminobutane adalah sebesar -50 °C, dan berbentuk cair pada suhu ruang.
16. a kitten and a basket has a mass of 3 kg . A hamster and a similar basket has a mass of 1.4kg . the mass of the kitten is 5 times the mass of the hamster .a. what is the mass of the hamster ? , b. what is the mass of the kitten ?
kitten = x ,hamster = y and baskest = z
x+z = 3 kg
y+z = 1,4 kg
z = x- y = 3 kg - 1,4 kg = 1,6 kg
x+y = 4,4 kg - 1,6 kg = 2, 8 kg
x = 5y
5y +y = 2,8 kg
6y = 2,8 kg
y = 2,8 kg /6
y = 0,47 kg
x = 5y
= 5 * 0,47 kg
= 2,35 kg
a. mass off hamster = 0,47 kg
b. mas off kitten = 2,35 kg
bonus...mass of basket = 1,6 kg
thank's
17. A basket with 42 watermelons has a mass of 81950 g.The same basket with 31 watermelon has a mass of 61105 g.If each watermelon has the same mass, what is the mass of the basket ?
42 watermelons + basket = 81.950 g
31 watermelons + basket = 61.105 g -
-----------------------------------------------
11 watermelons = 20.845 g
watermelon = 1.895 g
then,
31 x 1.895 + basket = 61.105 g
58.745 + basket = 61.105 g
basket = 2.360 g
18. the higher an object is from the ground, the greater the amount of _______ potential energy it has.
Jawaban:
gravitational potential energyThe amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.

19. The mean mass of five boys is 62 kg. When the mass of a boy is excluded, the mean mass of the remaining four boys becomes 64 kg. Find the mass of the boy that has been excluded.
Penjelasan dengan langkah-langkah:
Let the mass of the excluded boy be "x".
The mean mass of the five boys is 62 kg, so the total mass of the five boys can be expressed as 5 * 62 = 310 kg.
And, the mean mass of the remaining four boys after excluding the one boy is 64 kg, so the total mass of the remaining four boys can be expressed as 4 * 64 = 256 kg.
So, we have the equation: 310 - x = 256 + x,
Solving for x: x = (310 - 256)/2 = 27 kg.
So, the mass of the excluded boy is 27 kg.
Jawaban:
the answer is 54 kg, sorry for messy handwriting
