Step-by-step explanation:
used graphing calculator
Remark
The idea here is to take any two successive terms and divide one by the other. which is the divisor and which the dividend will be discussed below.
Step One
Set up the ratio for the common ratio between terms that come one after another.
Mathematically this is written as
r =

So just to see how this looks
t_(n + 1) = 3
t_n = 9
r =

r = 1/3
Does this work for other examples? Let's try a more complicated looking one.
t_(n) = 1/9
t_(n+1) = 1/27
r = t_(n + 1) / t_n
r =

r =

r = 1/3
To begin with, we have to multiply 16 by 5, to determine how many ounces are in the bags. we get 80, no? we then divide 1680 by 80 to receive 21. your answer is 21.
Answer:
0.85 Euros have the same amount as 1 U.S dollar.
Step-by-step explanation:
Given : The equation 
To find : Number of Euros which has same value as D U.S. dollar ?
Solution :
The equation 
Where, E= amount of Euros
D= amount of U.S dollar.
Now for 1 U.S dollar we put D=1,


Therefore, 0.85 Euros have the same amount as 1 U.S dollar.
Let the battery life = X
then 9.54% of X = 1.908
solve for X. <span>9.54% is very close to 1/10. So you can estimate which of the choices comes nearest to 1.908 by finding one tenth of each choice. Then check the choice by multiplying its value by 0.0954 to see if you get 1.908. Phone B which is 25.
