I see, thank you for your time! :)

ask your mom 

4/12  = 1/3

So

(1/3) (1/3) (1/3)   =  1/27  ≈ 0.037037037037037

or its 1/27 

Bakar's Distance divided by his rate  = his total time   =  6km / [ 4km/h ]  =  3/2 hr

And Ali's Distance  divided by his unknown rate , R,  rate  = his total time  = 6km / [ R km / h ]

And Bakar's time  plus 1/2 hr   =   Ali's time .......so

(3 / 2)   + (1/ 2)  = 6 / R   simplify

[ 6 + 2] / 4=   6 / R

[ 8 / 4]   = 6 / R

2 = 6 / R     and we can write

1/2 =  R / 6    multiply both sides by 6

3  = R      and Ali's rate  = 3 km / hr

0.037037037037037

\(\text{Slant height}=\dfrac{\frac{6}{2}}{\sin45^{\circ}}=3\sqrt2\\ \text{Surface area} = 6^2 + 4\times \dfrac{1}{2}\times 6\times 3\sqrt2\times \sin45^{\circ}\\ \qquad\qquad\;\;\;\;\;\!\;\;\!\!=36 + 36 \\\qquad\qquad\;\;\;\;\;\!\;\;\!\!=72\)

Area of any triangle: a and b are 2 side lengths of the triangle and C is the included angle of a and b, then area = \(\dfrac{ab\sin C}{2}\).

Good job for giving "Your daily help and support"!!

But actually, what does it mean? Can you explain further?

Quadratic formula?

For any \(ax^2 + bx + c =0\), the solutions for x is \(\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}\)

Its prime factors are: 180 = 2^2 * 3^2 * 5

\(\dfrac{14\not\text{m}}{20\not\text{m}}=\dfrac{14}{20}=\dfrac{7}{10}\)

-2 < 3 - 5x < 18

-5 < -5x < 15

-3 < x < 1

Using calculator, 9.6*7.8-0.53*86/4.95 = 65.67191919.......

Therefore the number correct to 1 sig. fig.(I'm so lazy to type XD) is 70 because the "6" in 65.67191919....... is a significant figure.

3 x 4 <--- Think about adding 3 for 4 times.

= 3 + 3 + 3 + 3

= 12 

Just an hour or two is okay I think.

Your bf/gf have their own life, maybe he/she have to go to eat dinner, so if you don't let him/her go, he/she may miss dinner... So that's not good. <--- Personally thinks this also means you don't care for him/her.

Agree.

Besides basic stuff, nothing can be used outside school.

Calculus is one of the example.

Differentiation and integration have no use outside school, except you're an engineer.

Especially in Hong Kong, we have to learn ancient Chinese!! <---- what the h*ll

Btw ABCDE

your mind use subconscious all this you know for this reason 2 people react different in the same situation

Nope. The special constant pi have infinitely many digits.

well i want detells 

\(\dfrac{36}{90}\\ =\dfrac{2}{5}\times 100\%\\ =40\%\)

First step: Simplify fraction and times 100%<-- because 100% just equals 1.

Second step: Multiply 2/5 to 100.

Hmm

Rational number?

What you listed are divisors of 1,700.

Its unique factors are 1,700 = 2^2 * 5^2 * 17

1.5 * 10⁶   *   1.2 * 10⁶

= 1.8 * 10⁶ * 10⁶

= 1.8 * 10¹²

= 1.8 trillion,     or 1 trillion 800 billion

yup anytime
