In the first part of your answer, why did you not include: 4+0, OR 0+4??.

3.09 x 10^5

309,000 in scientific notation is \({\color{blue}3.09\times 10^{5}}\)   !

FYI: If a number is divisible by 9, the sum of all its digit is divisible by 9

        If a number is divisible by 4, the last 2 digits is divisible by 4

************************************************************************************************************

Because 56 is divisible by 4, 12ab56 must be divisible by 4 no matter what a and b is.

1 + 2 + a + b + 5 + 6 = 9x

14 + a + b = 9x

9x may be 18 or 27.

Let's first consider the case of 9x = 18.

14 + a + b = 18

a + b = 4  <---- This is easy maths.

a = 1 or b = 3

OR

a = 2 or b = 2

OR 

a = 3 or b = 1

3 possibilities of a + b. Then we add them up:

3(a + b)

= 3(4) <---- because each pair of a + b in this consideration adds up to 4.

= 12. 

Now consider the case of 9x = 27

14 + a + b = 27

a + b = 13 <----- This is still easy maths.

a = 4 or b = 9

OR

a = 5 or b = 8

OR

a = 6 or b = 7

OR

a = 7 or b = 6

OR

a = 8 or b = 5

OR

a = 9 or b = 4

6 possibilities of a + b. Then add them up again:

6(a + b)

= 6(13)

= 78

Now we add up the number we got in last part and we get in this part.

12 + 78 = 90. Final answer.

\(|-X+Y|\geq 4\\ Y-X \geq 4 \text{ or }X - Y \geq 4\)

\(\boxed{\text{The opposite side of an angle: The only side in a triangle that isn't adjacent to it.}}\)

\(\boxed{\text{hypotenuse: the longest side in a right angled triangle.}}\)

x is an angle, then sin x (that's the usual abbrieviation for sine)means \(\dfrac{\text{opposite side of x}}{\text{hypotenuse}}\)

7 x 71 - 13.7 = 483.3

Hmmmmm....is there another answer?   When I take footSTEPS, I leave footPRINTS behind....not footsteps.

I have some questions for you Allycat.

Who let you out of your cage?

Do you still have your claws?

What brand of thorizine do you take?

Thank you so much, Melody. This answer is perfect. I forgot to mention the altitude remains constant and dx/dt is in fact -600km/h, but you safely assumed those.

1/2 x 1/2 x 1/2 x 1/2 x 1/2 x 1/2 =  1/64

This is basically the PV of an ordinary annuity with a couple minor adjustments:

1) Since his payments are adjusted for inflation of 3% per year and the interest he earned is 6% per annum, we have to find the net of the two rates as follows:

1.06 / 1.03 =2.91262%. We also have adjust his first payment by 3% inflation rate as follows:

$50,000 / 1.03 =$48,543.69.

Now we can use the ordinary annuity formula to find the PV of all his 25 payments as follows:

PV=P{(1 + R)^N - 1]*[1 + R]^-N * R^-1}=PV OF $1 PER PERIOD.

PV=48,543.69{[(1 +0.0291262) ^25 - 1] * [1 + 0.0291262]^-25 * 0.0291262^-1}

=$853,587.68. This is PV of his annuity.

2)-

We can also sum up all his future payments, using summation formula, on any good calculator such as Wlofram/ Alpha engine as follows:

∑[50000*1.03^n / 1.06^(n+1)], n=0 to 24 =$853,587.68. And here is the link to W/A:

175000(1+10.1)^11

175,000 x (1.101)^11

175,000 x 2.881778

=$504,311.14

555.55555.Only know that because I used a calculator.

68–72–76–80-84.No offense but I'm a little suprised you don't know that.

If you are 2, then how can you type?

12ab56 is a multiple of 36. Find the sum of all possible values of a+b.

Since the sum of the given digits =1+2+5+6=14, therefore the sum of the 2 missing digits + 14 must be divisible by 9 and 4, since 36=2^2 * 3^2. The 2 digits that will meet that condition are:

1+3 =4, or 3 +1 =4

2+2=4

4+0, or 0+4=4

4+9, or 9+4 =13

5+8, or 8+5 =13

6+7,or 7+6 =13

So, in total you 11 intrchangeable pairs of numbers that will meet the condition specified.

200 000 000 000 000 000 000 000 / 7,400,000,000 =~27,027,027,027,027 stars per person.

P.S. Tell your teacher that the size of Universe just grew by a factor of 10 or even 20!!!.
