Answer:
Step-by-step explanation:
15/3= 5
Orrrr
15/-3=-5
111=100(1.0153)^x
Solve for x
X=log(111÷100)÷log(1.0153)
X=6.9years round the answer
X=7 years
So in what year
2000+7=2007
In the year 2007
Answer: 0.6 in 10 % ; 0.4 in 15 %
Step-by-step explanation:
1. (x*10%) + (y*15%)/ x+y=12%
2. x+y = 1 x= 1-y
(0.1x + 0.15y/ x+y= 12/100) * 100
(10x + 15y/x+y = 12)*(x+y)
10x+15y= 12x + 12y
-2x=-3y
2x = 3y 2(1 - y)= 3y
2-2y=3y 2= 5y
y= 0.4
x= 0.6
