Answer:
5.33
Step-by-step explanation:
move the 4 out of the summation because just a constant multiplier
4 *sum from 1 to 10 for (1/4)^(n-1) [sorry i don't know how to write sums using latex)
The formula for the geometric sum is :
First term*(1-multiplier^n)/(1-multiplier), formally 
Here multiplier is 1/4
First term is (1/4)^(1-1) = 1
Thus the value of sum is
which equals 
We factored out 4 so its
which is 
This equals 5.333328247 which is 5.33 to the nearest hundredth
Answer:
The 5 is in the thousandths place.
825/1000
Step-by-step explanation:
Simplified this would be 33/40
825/1000 Divide the top and bottom by 25
It is the bottom right one because the amount he walked has to be greater than 200
Multiply both sides by 7. w=<span>105</span>
38,956 in expanded form is (3 x 10,000)+(8 x 1,000)+(9 x 100)+(5 x 10)+(6 x 1).
