Jawabannya: gak tau6. sarah has 17 sweets. Alia has 3 less sweets than sarah. How many sweets does Alia have?
Jawab:
14
Penjelasan dengan langkah-langkah:
Sarah = 17
Alia has 3 less sweets than Sarah :
Alia = Sarah - 3
Alia = 17 - 3
Alia = 14
7. Let U = {positive square numbers less than 30} and A = {all even numbers} . Find the complement of A.
Jawab:
A complement = {1, 9,25}
Penjelasan dengan langkah-langkah:
U = {positive square numbers less than 30}
berarti,
U = {bilangan kuadrat positif kurang dari 30}
U = {1, 4, 9, 16, 25)
A = {all even numbers}
A = {semua bilangan genap}
A = {2,4,6,8,10,12,dst sampai tak hingga}
A complement berarti, semua bilangan yang tidak ada di himpunan A, yaitu :
A complement = {1, 9,25}

9. how many positive integers less than 1000 are not divisible by a 1 digit prime
I will use 1 digit prime as = 2,3 and 5.
Instead of figuring out how many are not divisible by 2, 3 and 5, let’s figure out how many ARE divisible by those values.
How many numbers are divisible by 2?1000 ÷ 2 = 500 → ADD 500
→ {2, 4, 6, 8, 10, 12, 14, 16, 18, 20 … 996, 998, 1000}How many are divisible by 3?
1000 ÷ 3 = 333 → ADD 333
→ {3, 6, 9, 12, 15, 18, 21, 24, 27, 30 … 993, 996, 999}How many are divisible by 5?
1000 ÷ 5 = 200 → ADD 200
→ {5, 10, 15, 20, 25, 30, 35, 40 … 990, 995, 1000}
BUT 500+333+200 = 1033, more numbers than we started with.We have counted the multiples of 6 twice, so we have to subtract the overlap.
How many numbers are multiples of 6?
1000 ÷ 6 = 166 → SUBTRACT 166
→ {6, 12, 18, 24, 30, 36, 42, 48 … 984, 990, 996}We have counted the multiples of 10 twice, so we have to subtract the overlap
How many numbers are multiples of 10?
1000 ÷ 10 = 100 → SUBTRACT 100
→ {10, 20, 30, 40, 50, 60, 70 … 980, 990, 1000}We have counted the multiples of 15 twice, so we have to subtract the overlap
How many numbers are multiples of 15?
1000 ÷ 15 = 66 → SUBTRACT 66
→ {15, 30, 45, 60, 75, 90, 105, 120 … 960, 975, 990}
BUT we are not done yet: 1033 - 166 - 100 - 66 = 701
We subtracted the multiples of 30 three times, when we should have only subtracted them twice, so we need to add the triple overlap back to our sum.
How many numbers are multiple of 30?
1000 ÷ 30 = 33 → ADD + 33
→ {30, 60, 90, 120, 150, 180, 210 … 930, 960, 990}
We now have 701 + 33 = 734 numbers that are multiples of 2, 3 or 5.
How many numbers between 1 and 1000 are not multiples of these three numbers? Subtract that sum from 1000 and what do you get?
Here they are:

16. Find how many different odd four digit numbers greater than 4000 can be formed using the digits 1,2,3,4,5,6,7
Jawab:
320 macam
Penjelasan dengan langkah-langkah:
karena satuan harus ganjil, maka :
{1,3,5,7} ada 4 satuan
Karena harus lebih dari 4000, maka :
{4,5,6,7} ada 4 satuan
untuk angka ratusan :
{1,2,3,4,6} (ceritanya sudah diambil 2) ada 5 satuan
untuk angka puluhan :
{1,2,3,4} ada 4 satuan
Kalikan semuanya
4 x 4 x 5 x 4 = 320 macam
Transformasi bahasa :
odd = ganjil
different = berbeda
greater = lebih besar
formed = dibentuk

20. Consider all pairs of counting number whose sum is less than 11. The two numbers of a pair could be either the same as each other or different. How many different products are possible if the two numbers are multiplied?
Pertidaksamaan linear dua variabel adalah salah satu jenis dari pertidaksamaan dengan pangkat tertinggi dari variabel adalah dua. Consider all pairs of counting number whose sum is less than 11. The two numbers of a pair could be either the same as each other or different. The different products are possible if the two numbers are multiplied are x + y < 11 and [tex]xy[/tex] = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

Consider all pairs of counting number whose sum is less than 11. The two numbers of a pair could be either the same as each other or different.
Ditanyakan:
How many different products are possible if the two numbers are multiplied?
Jawab:
Misalnya x = 1 maka:
[tex]x+y=1+y < 1+10 < 11[/tex] dan [tex]x.y=1.y=y[/tex]
Misalnya y = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 maka x + y < 11 and [tex]xy[/tex] = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
