Jawaban:
What is the median mass of the 8 children?
The middle value of the masses of the 8 children is 61 kg
Penjelasan:
51 kg. 52 kg, 58 kg, 60 kg, 62 kg, 64 kg, 64 kg, 68 kg
60 + 62 = 122/2 = 61 kg
2. 2/3 of the mass of a lobster is equal to 3/8 of the mass of a king crab. the difference in their masses is 7/10 kg. what is the mass of the king crab?
Jawab:
1.6 kg
Penjelasan dengan langkah-langkah:
Let : Mass of a lobster = L
Mass of a king crab = K
So :
[tex]\frac{2}{3} L = \frac{3}{8} K\\\\L = \frac{3}{8} K \ x \ \frac{3}{2} = \frac{9}{16} K\\\\K > L, so\\\\K - L = \frac{7}{10} \\\\K - \frac{9}{16} K = \frac{7}{10}\\\\\frac{7}{16} K = \frac{7}{10}\\\\K = 1.6 kg[/tex]

Nyatakan jawaban Anda sebagai bilangan campuran dalam bentuk paling sederhana.
Jawab:
[tex]1\frac{3}{5} kg[/tex]
Penjelasan dengan langkah-langkah:
[tex]l[/tex] = mass of lobster
[tex]k[/tex] = mass of a king crab
2/3 of the mass of a lobster is equal to 3/8 of the mass of a king crab
[tex]\frac{2}{3}l=\frac{3}{8}k\\\frac{l}{k}=\frac{3}{8}\times \frac{3}{2}\\\frac{l}{k}=\frac{9}{16}\\l:k=9:16[/tex]

[tex]l=9x\\k=16x[/tex]
difference in their masses is 7/10 kg
[tex]k-l=\frac{7}{10}\\16x-9x=\frac{7}{10}\\7x=\frac{7}{10}\\\\x=\frac{7}{10}\times \frac{1}{7}\\x=\frac{1}{10}[/tex]

12. yg bisa bantuin yakk.. the sum of the three angles of triangle is 180degree. the sum of the angle is equal to the third angle and the difference of the two angles is equal to 2/3 the third angle. find the angles of this triangle
Misalkan sudut A,B,C
A=B
A+B=⅔C
A+B+C=180
1:1:3=180
maka
2A+3A=180
5A=180
A=180/5
A=36
A+B+C=180
36+36+C=180
C=180-72
C=108
Jadi sudut A=36, B=36 dan C=108

14. the sum of three angles of triangle of 180 deg. the sum of two of the angles is equal to the third angle and the difference of the two angles is equal to 2/3 the third angles find the angles of this triangle?
suppose that :
x = first angle
y = second angle
z = third angle
The sum of three angles of triangle of 180°
So :
x + y + z = 180
The sum of two of the angles is equal to the third angle
So :
x + y = z
The difference of the two angles is equal to 2/3 the third angles
So :
x - y = (2/3) z
subtitute x + y = z
x + y + z = 180
z + z = 180
2z = 180
z = 180/2
z = 90
x + y = z
x + y = 90
x - y = (2/3) z
x - y = (2/3) (90)
x - y = 60 >>> x = 60 + y
subtitute x = 60 + y
x + y = 90
60 + y + y = 90
60 + 2y = 90
2y = 90 - 60
2y = 30
y = 30/2
y = 15
x = 60 + y
x = 60 + 15
x = 75
We got :
x = 75
y = 15
z = 90
So, the angles are 75°, 15°, and 90°

16. The mass of Bag A is ¾ kg. Bag A is the heaviest. The difference between the masses of Bag A and Bag B is 7/12 kg. Bag B is the lightest.The difference between the masses of Bag B and Bag C is 1/6 kg.What is the mass of Bag C? Express n explanation your answer in its simplest form.
Jawaban:
1/3 kg
Penjelasan dengan langkah-langkah:
berat A=3/4 kg
Berat A- berat B= 7/12 kg
3/4- berat b=7/12
berat b= 3/4-7/12=2/12=1/6 kg
Berat c- berat b= 1/6 kg
berat c -1/6=1/6
berat c= 1/3 kg
Diketahui:
[tex]A = \frac{3}{4} = \frac{9}{12}[/tex]
[tex]A - B = \frac{7}{12}[/tex]
[tex]C - B = \frac{1}{6} = \frac{2}{12}[/tex]
Ditanya: C ?
Jawab:
[tex]A - B = \frac{7}{12}\\ \\ B = \frac{9}{12} - \frac{7}{12} = \frac{2}{12}[/tex]
substitusikan nilai B ke persamaan C-B
[tex]C - B = \frac{2}{12}\\ \\ C = \frac{2}{12} + \frac{2}{12} \\ \\C = \frac{4}{12} = \frac{1}{3}[/tex]
jadi massa dari tas C adalah [tex]\frac{1}{3}[/tex] kg
