Answer:
Step-by-step explanation:
the percentage error: P
Approximate value=a 1.41
Exact = e(1.41421356 or √2)
p=[(e-a)/e]×100
p=[√2-1.41)/√2]×100
p=0.29794385 ≅0.30 or 30 percent when rounded to the nearest hundredth
b: p=[(π-3.14)/π]×100=0.05069573≅0.05 =5 percent when rounded to the nearest hundredth. in the pi case the percentage of error is small 5 % but in the case of square roots the percentage id higher(30%). in this case it is better to round the answer at the end of calculation( math problem)
c) sometimes when rounding square roots or irrational number like pi it is useful to use decimal approximate, in the case of pi the percentage rate was 5 percent which is very low comparing to the square root which is 30 %.
<u><em>Answer:</em></u>
Elena's running speed is 5 miles/hour
<u><em>Explanation:</em></u>
The speed is defined as the covered distance per unit time
<u>In the problem, we have:</u>
The distance covered is the length (circumference) of the circular track which is given as
of a mile.
We are also given that she completes each lap (she completes
of a mile) in
of an hour
To get her speed, we will divide the distance covered by the time taken to cover this distance
<u>This is done as follows:</u>
speed =
miles/hour
<u>This means that:</u>
Elena can run 5 miles each hour
Hope this helps :)
