sorry if it's wrong, hope it helps^^
Jawaban:
4,55 + 6,90 = 11,45
Penjelasan:
total mass of the two bags of fruits is 11,45 kg
2. 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
3. A kitten and a basket has a mass of 3 kg. A hanster and a similar basket has a mass of 1.4 kg. 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?
hamster = x
kitten =y
basket=z
y=5x
x + z = 1,4
y+ z = 3. (+)
x-y = -1,6
x-5x=-1,6
6x = 1,6. x =0,267
y = 5x=5×0,267=1,335

5. 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
6. 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

10. Soo Ching has a mass of 20.8 kg more than Simon Their totalmass is 94.6 kg. Find Simon's mass.
Answer:
73,8 kg
Explanation:
total = Soo Ching's mass + Simon's mass
94,6 = 20,8 + x
x = 94,6 - 20,8
= 73,8 kg
11. A Box with 4 simiral books has a mass of 6.26kg. The mass of the box is 0.5 kg. Find the mass of one book and express your answer in kilograms and grams. HELP
Jawab:
1.44 kg = 1440 grams
Penjelasan dengan langkah-langkah:
The mass of 4 similar books = 6.26 kg - 0.5 kg = 5.76 kg.
The mass of each book = 5.76 kg : 4 = 1.44 kg = 1440 grams

13. 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

14. Mina always brings her own shopping bags to buy fruits. A bag with 62 lemons in it has a mass of 4.55 kg. The same bag with 36 lemons in it has a mass of 2.86 kg. Find the mass of the bag when it is empty in grams
Jawaban:
ish rumit bet dahshjdj
Penjelasan dengan langkah-langkah:
palalalalallalalal
Jawaban:
520 grams
Penjelasan dengan langkah-langkah:
(4.55 - 2.86) : (62 - 36)
= 1.69 : 26
=0.065 (mass of a lemon im kilogram)
0.065 x 62 = 4.03 (total mass of the lemon in kilogram)
4.55 - 4.03 = 0.52 kilogram (bag's weight)
=520 grams

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

17. The bars of chocolate in a box have total mass of 15/16 kg. Each bar of chocolate has a mass of 5/32 kg. How many bars of chocolate are there in the box?
15/16:5/32=15/16x32/5=480/80=6barstotal mass = 15/16 kg
each bar = 5/32
many bar = total mass ÷ each bar
=15/16 ÷ 5/32
= 15/16 × 32/5
= 480/80
= 6
chocolate are there in the box have 6 bars
18. When a box contains 100 identical balls, it has a mass of 27.8 kg. The empty box has a mass of 800 gram. Find the mass of a ball in kilograms. * a. 0.17 Kg b. 0.27 Kg c. 0.37 Kg d. 0.47 Kgplease bantuu batas waktu jam 14.00segera tolong kakak cantik bangett aku doain yg jawab makin cantik dan pintar
Jawab:
B. 0,27 kg
Penjelasan dengan langkah-langkah:
27,8 kg = 27.800 gram
Empity Box = 800 gram
100 Balls = 27.000 gram
1 Ball = 270 gram = 0,27 kg
19. 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

20. calculate the molar mass of a compound if 0.372 mol of it has a mass of 152g
Jawaban:
Massa molar suatu senyawa yang memiliki 0,372 mol dan massa 152g adalah 408.6g/mol
MENGHITUNG MASSA MOLAR :
Massa molar suatu zat dapat dihitung dengan membagi massa zat dengan jumlah molnya . Itu adalah;
Massa molar (g/mol) = massa (g) no. mol ( mol)
Berdasarkan pertanyaan ini, suatu senyawa memiliki 0,372 mol dan massa 152g, maka massa molar senyawa tersebut adalah sebagai berikut:
Massa molar = 152g 0,372mol
Massa molar = 408.6g/mol
Jadi, massa molar suatu senyawa yang memiliki 0,372 mol dan massa 152g adalah 408,6 g/mol.
