HAPPPY BIRTHDAY ROSALA!

Heyyyy it's been so long. I'm in contact with Rosala still through Instagram I'll let her know to come back and check out the website. This is an insane coincidence that I decided to check out the website around her birthday, it's almost like fate. I just saw TitaniumRome online and wanted to check. Ahh, it feels so good and nostalgic to be back here. I hope everyone's doing well :))

3/4 of $600 = $450 

(1-0.2=0.8)

80% of $450 = $360 (the lemons she sold at a loss)

1/4 of 600 = 150

(1+0.2=1.2)

120% of 150=$180 (the lemons she sold at a gain)

180+360=540

540/600= 90% 

100-90= 10% 

She lost 10% in the whole transaction.

I hope this is right or this will be awkward :)

It is correct.

(15,8) is the distance from centre to circumference aka the radius.

Create a right angle triangle around the points and work out the radius,

a^2+b^2=c^2

15^2+8^2=289

sqrt(289)=17

x^2+y^2=17

sorry went brain blank a second

I honestly haven't been on in a while, a couple of years in fact. The people here remained kind and friendly but the things that were immediately noticeable after 2-3yrs was the quality of questions on the website, it's not fair. Also, this site definitely has the potential to grow bigger and expand to help more people but I don't know what's up with the direction it's taking...

I think he's asking for the proof of pi or why it exists.

So,

Area= 180ft

Perimeter= 54ft

Simply meaning, two numbers that multiply to give 180 and add (x2 due to 4 sides) to give 54.

EG

$\\X ⋅ Y\\ \\X+X+Y+Y\\ $

Factors of 180:

1,2,3,4,5,6,9,10,12,15,18,20,30,36,45,60,90,180

Numbers have to be below 54 itself to add up to it

1,2,3,4,5,6,9,10,12,15,18,20,30,36,45,

Find two factors that multiply to 180 that add to 54 (all 4 sides)

12 and 15

12*15= 180

12+12+15+15=54

Length must be 15ft

By diagonal, I assume you mean a diagonal line intersecting through the rectangle (unless you only mean the length of the patio itself).

$\\12^2+15^2=369\\ \\\sqrt{369}=19.2ft\\$

When squared that would be 369ft.

ab+aaan=

ab+a^3n

(Lol, i don't even know why...)

I haven't got a lot of experience in trigonometry but...

Cosine=Cos

Cos = The adjacent side / hypotenuse

7 * 7 = 49                         

Hi!  :D

pi = 3.14 (Approx

3.14*10 = 31.4 (Approx

pi = 3.14 (Approx

3.14*10 = 31.4 (Approx

It's in it's simplest form. 

You can't solve it it's an expression not equation. 

1/2 divided by 1/3

=  

2/1 multiply by  1/3

= 

2/3

Not in everyone's eyes.

Try and you'll see.

Yes you can that'll give you 65a,

but you wouldn't be able to add it.

As they are not 'like terms' so if you were to add them it would stay the same.
