The answer is 5 feet.
1/4 = 1.25/x
x = 4•1.25
x = 5
Answer:
For the 7th term we have 3 decimals of approximation but our value is 0.000198 higher than the error required, so we can use the 8th term and we have that 
and with this we have 4 decimals of approximation so if we add the first 8 terms we have a good approximation for the series with an error bound lower than 0.0001.
Step-by-step explanation:
Assuming the following series:
We want to approximate the value for the series with less than 0.0001 of error.
First we need to ensure that the series converges. If we have a series 
where 
[/tex] or 
where 
for all n if we satisfy the two conditions given:
1) 
2) {
} is a decreasing sequence
Then is convergent. For this case we have that:
And 
because 
and 
So then we satisfy both conditions and then the series converges. Now in order to find the approximation with the error required we can write the first terms for the series like this:
For the 7th term we have 3 decimals of approximation but our value is 0.000198 higher than the error required, so we can use the 8th term and we have that and with this we have 4 decimals of approximation so if we add the first 8 terms we have a good approximation for the series with an error bound lower than 0.0001.
To avoid confusion, remember PEMDAS. This is the order of operation.

21 ÷ 7 + 20 * 102 * 2 - 3
No parenthesis and no exponents, proceed to multiplication.
20 * 102 * 2 = 4,080
Then, perform division
21÷7 = 3
Then, do addition
3 + 4080 = 4083
Lastly, do subtraction
4,083 - 3 = 4,080
So, 21 ÷ 7 + 20 * 102 * 2 - 3 = 4,080
THEREFORE THE ANSWER IS 4,080
D. Multiply because you don’t have parentheses or exponents so you would multiply
Answer:
b=2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
