Here's how many digits of π I can memorise:

3.14159265358979323846264338327950288...

Now, separate those digits into groups of 10 digits:

3.141592653 | 5358979323 | 8462643383 | 27950288...

Now we have more than 30 digits of π.

The 32nd digit of π is 7.

Eww... Disgusting!

Correct Answer:

No matter how many ways of replacing 9 + 10, it will still equal 19.

9 + 10 = 5 + 5 + 3 + 3 + 3

= 8 + 8 + 3

= 16 + 3

= 19

9 + 10 = 9 + 9 + 1

= 18 + 1

= 19

9 + 10 = 10 + 9

= 19

9 ones

add 1 ten 0 ones

= 1 ten 9 ones

= 19

\(4k - 6 = -2k - 16 - 2 \\ 4k - 6 = -2k - 18 \quad | \, + 18 \\ 4k + 12 = -2k \quad | \, +2k \\ 6k + 12 = 0 \quad | \, -12 \\ 6k = -12 \quad | \, ÷ 6 \\ \therefore k = -2\)

Actually, you are multiplying by 100 %, not 100.

As 100 = 100 * 100 % = 10 000%

5*4*3*2*1 = 120

Thanks btw

20 ÷ 25 = 20 / 25

             = 4 / 5

            = 0.8
