Answer:
(B) 7.1 is the estimated square root of 50
Step-by-step explanation:
A. √50 = √2 √25
= 5√2.
Jaclyn did not take the square root of 2.
B. We estimate the square root of 2.
Trial and improvement:
It must lie between 1 and 2 so we try 1.5:
1.5 * 1.5 = 2.25
Its < 1.5 so try 1.4
1.4 * 1.4 = 1.96.
So it is a little above 1.4.
Try 1.45:
1.45 * 1.45
1.45
* 1.45
-------
725
5800
14500
2.1025
= 2.1025.
- this is above 2 so the answer is between 1.40 and 1.45 but closer to 1.4.
A good estimate is 1.42
So the square root of 50 is about 5*1.42 = 7.1
I got 5. If you divide 210 by 3, you get 40 miles an hour. You then divide 200(miles) by 40(how fast your going) to get 5.
