Step-by-step explanation:
Answer:
1st statement is true
Step-by-step explanation:
The 1st statement is true since .25 is 25/100
The 2nd statement is false since 20 / 10 = 2 not .20 which is 2/10
The 3rd statement is false since 2/3 = .6666667 not .23
The 4th statement is false since .4 = 4/10 not 1/4 which is .25

Answer:
45
Step-by-step explanation:
Use the geometric sum formula for in infinite sum. 20 terms of this basic formula is close enough The 20th term is 8.6 * 10^-10 which means this goes out to a number with 9 zeros after the decimal and before the 8.
Put another way, the tenth number of this series is the only one affected.
When you use a spreadsheet, it seems to know that the answer is 3/2 as the solution to the sum.
Solution.
Sum = a / (1 - r)
a = 1
r = 1/3
Sum = 1 / (1 - 1/3)
Sum = 1 // 2/3
sum = 3/2
Now you can worry about the 30.
30 * sum(1/3)^n = 30* 3/2 = 45
