3. the mass of a watermelon is 7/1 kg. the mass of a apples is 2/5 kg less than the mass of the watermelona. what is the mass of the applesb.what is the total mass of the apples and watermelon
Diketahui:
Berat semangka = 7/1 kg
Berat apel = 2/5 kg kurang dari semangka
Maka:
a. Berat apel = 7/1 - 2/5
= 35/5 - 2/5
= 33/5 = 6 3/5
b. Berat apel dan semangka = 7/1 + 6 3/5
= 35/5 + 33/5
= 68/5 = 13 3/5

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

14. 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
