Do you mean 'circumference' instead of 'circumstance'?
circumference = 22m
radius = circumference divided by 2 pi. =\(\dfrac{22}{2\pi} =\dfrac{11}{\pi}\)
\(1.29167\\ =1 + 0.29167\\ =1+\dfrac{29167}{100000}\\ =\dfrac{129167}{100000}\)
If you mean k is a variable......
\((\sqrt{216k})^4\\ =(216k)^2\\ =46656k^2\)
I have proved that the answer to the question must have large numbers. LOL
.7272727272727272.............=8/11
Thanks Guest#2, I didn't know that!! :)
10(w - 4) = 4(w + 4) + 4w
10w - 40 = 4w + 16 + 4w
10w - 40 = 8w + 16
10w - 8w = 16 + 40
2w = 56
w = 28
Well, it is quite obvious!. Just multiply the monthly payment of 21.57 pounds by the number of months, or 42. So, 21.57 x 42 =905.94 pounds, of which 650 pounds is principal and 255.94 pounds is the interest.
Inside the {}, it contains the parameters for LaTeX commands!!
e.g. \frac{2}{5} will appear as \(\frac{2}{5}\)
e.g.(2) \sqrt{2x} will appear as \(\sqrt{2x}\)
\(5\times[3\times(-2)-10]\\ =5\times(-6-10)\\ =5\times(-16)\\ = -80\)
P(2 of 25 sections) (if the sections are same in shape and area) = 2/25.
Simple question.
Thank you for appreciating the calculator on the site :)
I am not a staff though but I appreciate the calculator too.
It can do large number stuff, it could do number theory but now not for some reasons, it can work out modulus, trig and inverse trig, matrices..... stuff!! :D
Notes: When will 1 + 1 not equals 2?
When does 1 + 1 = -2: 1 minutes before 1 minutes before is 2 minutes before.
When does 1 + 1 = 1: Mentioned above.
When does 1 + 1 = 10: Binary system.
:)
I asked this question not long ago, too. And my dad, who is likely to faint when doing maths, answered my question.
Me:'Why is 1+1 = 2?'
Dad:'NOOOO! 1+1 = 1!!'
This is just a habit of human beings from ancient times that 1 item plus 1 item is 2 items.
Why 1 + 1 = 1......
1 grain of sand plus 1 grain of sand is still 1 larger grain of sand!! :)
What do you mean by that long thing after 'John wants to buy a stereo for £650'?
That means the total amount = £650
ahhhhhh bright future XD
The Guest doesn't mean 0.72 he means \(0.\bar{7}\bar{2}\) for repeating decimals.
0.7272727272727272727......... divide by 100 = 0.00727272727...........
Let x = 0.727272727272727272727..........
x - (1/100) x = 0.72
(99/100)x = 0.72
99x = 72
x = 72/99 = 8/11.
1. A ceiling fan can rotate 150.5 times per minute. The fan rotated a total of 2,426.06 times. Which of the following is true?
\(t = Z/n\)
\(t = \frac{2426.06}{150.5min^{-1} } \) \(\times \frac{60s}{min}\)
\(t=967.2s \)
\(The \ fan \ was \ 967.2 \ seconds \ in \ operation. \ This \ is \ true!\)
There are infinite multiples of 60!! Do you mean factors?
First few multiples of 60: 60, 120, 180, 240, 300, 360, 420, 480, 540, 600, 660..........
Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60.
I will try to give all true statements...... LOL just a try......
1) 2426.06/150.5 = 16.12 <--- The fan have rotated for 16.12 minutes.
2) 150.5/60 = 2 61/120 <----- The fan can rotate 2 61/120 times for 1 second.
You have 1 cookie (YAY i love cookies) and someone gave you 1 more cookie, then you have 2 cookies!! :D
I would prefer multiply by 4 on each side......:
\(\dfrac{x-1}{2}+1=\dfrac{x+1}{4}\\ 2(x-1) + 4 = x+ 1\\ 2x - 2 + 4 = x + 1\\ 2x + 2 = x + 1\\ 2x - x = 1-2\\ x = -1\)
I got the same answer as asinus did!! That means hopefully we are both correct! :)
This is a fun question that 9'1's times 9'1's is 12,345,678,987,654,321. :D
LOL Guest #1, you need not do that to me in question #1.
\(\dfrac{(x^{-1}-y^{-1})}{(\pi x-\pi y)(x^2+9\sqrt{\pi}xy+8\pi y^2)}\\ =\dfrac{\frac{y-x}{xy}}{\pi(x-y)(x+\sqrt{\pi}y)(x+8\sqrt{\pi}y)}\\ =-\dfrac{\frac{1}{xy}}{\pi (x+\sqrt{\pi}y)(x+8\sqrt{\pi}y)}\\ = -\dfrac{1}{\pi xy (x+\sqrt{\pi}y)(x+8\sqrt{\pi}y)}\)
You are complexifying that question(Yeah you never heard that word..... I made it up!! :) )
