Answer:
Nolan correctly identified the square numbers before and after 18.
The square roots of them are 4 and 5.
Clearly, square root of 18 should lie between 4 and 5 only.
He, then carefully squared 4.1, 4.2, 4.3 etc. and identified that 4.3 squared is nearer to 18.
Since, Nolan is finding estimated square root, his steps are cool and he didn't make any error.
Answer:
1. Minor arc
2. 152
3. major arc
4. 298
Step-by-step explanation:
Start with $30.25.
Subtract $14.00 to isolate the amount of money spent on admission.
30.25-14.00= 16.25. As a group $16.25 was spent on admission.
Admission is 3.25 per person. Divide 16.25 by 3.25.
16.25/3.25=5.
5 friends went ice skating.
General Idea:
The relationship between rate(R), distance(D) and time(T) given below:

Applying the concept:
We need to make use of the formula to find Kelly's walking rate before and after her snack

Option A isn't correct because before snack Kelly walking rate is not 4/14 miles per hour.
Option B is <u>Correct,</u> Kelly walking rate after snack is 2 2/3 miles per hour.
Option C isn't correct because it doesn't took Kelly 2 hours longer to walk 1/6 mile than it did for her to walk 1/4 mile. It took 1/112 hour longer.

Option D isn't correct because 2 2/3 miles per hour is slower than 3 1/2 miles per hour.
Conclusion:
Option B is <u>Correct,</u> Kelly walking rate after snack is 2 2/3 miles per hour.
