123 + 359  =    ???   =  the original height above the ground

It is a confusing question but this is my interpretation

5+2430 = 2435

Yes Kit, guest has a valid point....

I will give a hint:

\(0.025\% = \frac{0.025}{100}\)

Multiply top and bottom by 1000  by moving the point 3 places in the direction to make the number bigger.

Whole numbers really do have a point, it is at the end and it is invisable.

Now that you have 2 whole numbers, top and bottom, simplify.

1.continuous 

I have assumed that the answer will be the same where ever P is put.   (P is on the incircle of course)

The easiest place to put P is on the midpoint of one of the sides.

Now all the distances are really easy to find.  

I will leave that to you though. 

U are def in my AoPS class

You didn’t give a hint. You just restated part of the instruction.

Yep, Melody was wrong.     

Since 7x8= 56 and 7x9= 63 the answer would be 8 since 63 is 2 higher than 61 or if you do this 7x8=56    
61-56= 5, so the bottom number is supposed to be equal to or less than, so if you go to do 61-63=

you can't do it.So that means the answer is definitely 8

Thx this helps a lot 

Same thing as hihihi and KSW said... but more detailed (i think)

\(2n+5=15\:\:\)

\(\mathrm{Subtract\:}5\mathrm{\:from\:both\:sides}\)

\(2n+5-5=15-5\)

\(\mathrm{Simplify}\)

\(2n=10\)

\(\mathrm{Divide\:both\:sides\:by\:}2\)

\(\frac{2n}{2}=\frac{10}{2}\)

\(\mathrm{Simplify}\)

\(n=5\)

By integration by parts, $\int_0^{10} xg''(x) dx = 18$.

Thank you

If two-thirds of a number is 10, we can write it out as 2/3x=10.

Multiply both sides by 3 to get 2x=30.

Simplifying we get x=15.

Checking our work 15*2/3=10

Vivek, I believe we have the same answer, but anyways, Guest could you specify where you think I got the problem wrong?

I forgot this but I remember the website I used to learn it.

Here it is: https://web.williams.edu/Mathematics/sjmiller/public_html/OSUClasses/487/ArithMeanGeoMean.pdf

It's a great notes sheet.

I'm getting 4//5 < t <= 5/2, so in interval notation the solution is \((4/5,5/2]\)

this is an aops prealgebra 2 problem (I'm taking the course rn and it was the first problem in week 1.) so I'll give @Choff a hint instead of the answer. 

try writing 0.025% as a fraction. What do you get? 

btw, @Melody is wrong...

To add on to @Guests's, the question is asking for what A-B is. so A-B=4-2=2

start by converting 12 1/2% (0.125) as a common fraction -> 1/8 

2000*1/8=250

this was posted twice but here is the answer

61/7=8 5/7 so the answer is 8

1-0.4=0.6

then it becomes the equation 0.6x=16

divide both sides by 0.6 to get $26.67

363 minutes actually...but 364 is also fine
