Equation - x = -3/10 + (10-1)
The original number is 9.3 because
x = -3/10 + (10-1)
x = -3/10 + 9
x = 9.3
Answer:
Step-by-step explanation:
When the interest compounds continuously, our formula is

If we start with 10000 and are looking for how long, t, it takes to double, we are looking for how long it will take for our account to have 2 times 10000. That's 20000. Therefore, our equation is

Divide both sides by 10000 to get

Take the natural log of both sides to "undo" that e:

Again, since ln and e undo each other what we have now is
ln(2) = .11t and
so
t = 6.3 years
Answer:
Step-by-step explanation:
As given Total Guavas = 40 ,
3 daughters,
Let share of Sharon = x
then by given condition ,
Naomi share = x+3 (3 more then Sharon
Also Kassie share = x+3+10 =x+13 (10 more then Naomi
Now
total shared = total
Naomi + Sharon + Kassie = 40
(x+3) +(x) +(x+13) =40
adding like terms with like we get ,
3x+16=40
3x=40-16
3x=24
x= 24/3
x= 8
hence Sharon share = x =8
Naomi share = x+3 =8+3 =11
Kassie share = x+13 = 8+13 = 21
