Also know that he always spend 1 GO per month.

Sorry, I change the finding-y part to: 

y # ?, know that: \(\dfrac{\sqrt{\left(200000000-44424621\right)\sqrt{3}}\times y^2}{\sqrt{2}\times y}=\dfrac{\sqrt[4]{12\times y^2}\times y}{2}\)

# only works with positive numbers

(This is an exercise I thought by myself, so I hope you will understand my mistakes.)

The number of large clips that weigh the same as 12 small clips is:

       12 x 2/3 = 8(large clips)

The number of tacks weigh the same amount as 12 small clips is:

       8 x 2 = 16(tacks)

Each hour, Alex and Benito make the amount of pies is:

        880 : 8 = 110(pies)

The number of pies made by Alex in 1 hour is:

        (110 + 10) : 2 = 60(pies)

Ali's smallest number is:

          5 - 1 = 4

The total of Ben's numbers is:

         128 - {[4 + (4 + 4)] x 5 : 2} = 98

Ben's largest number is:

        98 : 7 + 3 =  17

After transferred, each box has:

      48 : 3 = 16(apples)

The original number of apples in container A  is:

      16 + 9 = 25( apples)

My answer is (B) \(\pi\)

If Leith buys 8 kilograms of apples from this greengrocer, he will pay:

       $6 x 3 + ($6 x 20%) x (8 - 3) = $24

 The maximum percent error when 24 cm is measured is:

       1 : 24 \(\approx\) 4.2%

Sorry, I change the phrase "born to the South" to "born Nam"

Because Zagan only has purple and blue pens, so the value of x is:

            10 : 2 = 5

The number of women is: 100 - 59 = 41(women)

The number of  men were right- handed is: 59 - 3 = 56(men)

The number of women were right-handed is: 89 - 56 = 33(women)

The number of women were lefties is: 41 - 33 = 8(women)

The ratio of the women were lefties is: 8 : 100 = 8%

Two days after tommorow is 23rd

The 100th number is: 10 + 11 x 99 = 1099

The first number between 10 and 3000 is multiple by 7 is 14.

The last number between 10 and 3000 is multiple by 7 is 2996.

The number of numbers that are multiple by 7 between 10 and 3000 is:

       (2996 - 14) : 7 + 1 = 427

The volume of the rectangular prism is:

      5 x 7 x 3 = 105(cm²)

Tỉ lệ phần trăm của diện tích tam giác mới với tam giác ban đầu là:

\(\dfrac{\dfrac{110\%\times a\times120\%\times h}{2}}{\dfrac{100\%\times a\times100\%\times h}{2}}\)

= 132%
