10. The average mass of 8 students is 35 kg. The average mass of 8 students and 1 teacher is 39 kg. What is the mass of the teacher? help<3
Average mass 8 student = 35kg
Average 8 student + 1 teacher = 39kg
Mass of the teacher?
Average 8 student formula :
(Summation mass of 8 student) ÷ 8 = 35
y ÷ 8 = 35
y = 35 x 8
y = 280
Average 8 student + 1 teacher formula :
(Summation mass of 8 student + mass teacher) ÷ 9 = 39
(280 + mass tecaher) = 39 x 9
280 + mass teacher = 351
mass teacher = 71
∴ mass of the teacher is 71 kg

Jawab:
[3] 34 kg
Penjelasan dengan langkah-langkah:
Given that (the)
Number of students (n) = 3
ma = 33 kg, mb = 29 kg, mc = 40 kg
Find the average weight (Avg.)

12. The average mass of 9 sheep is 35 kg. The average mass of 9 sheep and 1cow is 64 kg. What is the mass of the cow?
Jawaban:
The mass of the cow is 325kg
Penjelasan:
TobeKnown:
9 sheep = 35 kg
9 sheep + 1 cow = 64 kg
TobeAsked:
mass of the cow = . . . . ?
Solving:
as 9 sheep + 1 cow is 64 kg, so that the total average mass of those 10 animals = 64 kg
total average = [tex]\frac {(9 × 35) + (cow)}{10}[/tex] = 64
(315) + (cow) = 64 × 10
315 + cow = 640
cow = 640 - 315
cow = 325 kg

18. The average age of the members in a family of five is 28. The average age of the three children is 14. What is the average age of the two adults?
Jawab:
Penjelasan dengan langkah-langkah:
Suppose :
x = total age of all family members
y = total age of all children
z = total age of all adults
x/5 = 28
x = 28 (5)
x = 140
y/3 = 14
y = 14 (3)
y = 42
x = y + z
140 = 42 + z
z = 140 - 42
z = 98
The average age of the two adults = 98/2 = 49 years.

Jawab:
Penyelesaian dibawah
Penjelasan dengan langkah-langkah:
Ahmad memiliki berat badan 60 kg. Itu 10 kg lebih berat dari Ashsa. Selisih berat antara ahsan dan achmad adalah 2 kali Selisih berat antara ahsan dan ashsa. jadi, berat ahsan adalah.....kg
Ahmad = 60 kg
Ashsa = 50 kg

x - 60 kg = 2x - 100 kg
100 kg - 60 kg = 2x - x
40 kg = x
Berat badan Ahsan dalam soal tersebut adalah 40 kg.
