after:
a: stickers of ann at the end
b: stickers of james at the end
a+b=117 (If they had a total of 117 stickers)
b=2*a (james has twice as ann stickers)
[input]solve( a+b=117, b=2*a )[/input]
{a=39, b=78}

or solve by hand: a+(2*a)=117 => 3a=117 => a=117/3=39 , b=2*a => b=2*39=78

before:
aa: stickers of ann at the beginning
bb: stickers of james at the beginning

aa*0.75=a (ann gave jamES 25% of her stickers)
aa=a/0.75=39/0.75= 52
bb=117-52= 65

let's check:
(52*0.75)+(65+52*0.25)= 117

how long would it take to double your principle at an annual rate of 7% compounded continuously?

nice question.

(1+0.07)^x = 2
[input]log(2, 1.07)[/input]

rule of thumb:
70 / percent ≈ number in years to double

i Cant figure out how to do this on the web calculator, its 1 whole then 3/5 so its like big 1 then 3 over 5, sorry cant explain it well

Hi, we have included a new fraction detection rule:

now you can enter fractions by using this syntax:

1 3/5

1_3/5

1+3/5

the equation goes like this .2 x 6.00=? and that's ur anwser for nickles.

1 3/5 , Type it into the calculator ; and it will automatically turn it into a fraction. or there's the fraction button ; it looks like an "N" Over a "D" ; push that button ; and enter in the values. (:

5000% = 50*100%= 50
so you have to find 1/50th of 2500
which equals 50

idk how the part under the / is called in english, but you have to take the smallest they have in common,
A) 6/10 + 7/10 = 13/10
B)5/4 + 2/4 = 7/4

1.79/(1-0.69)=5.77

if you mean they only payd 31% and saved out 69% of the original price

GuestFeb 6, 2012

Type into calculator entry bar: plot(sin(x),x=-180..180, -1.0..1.0)
or cos instead of sin or change domain by adjusting 180 to smaller or larger degrees;
adjust range by making -1 to 1 smaller or larger;
adjust to radians by selecting radian button at base of calculator and then adjust domain to suit

Hope that helps
