Answer:
7.3 to the nearest tenth.
Step-by-step explanation:
The square root is between 7 and 8.
The closest whole number is 7.
Divide 53 by 7:
= 7.57
Average of 7 and 7.57 = 7.29
Divide 53 by 7.29 = 7.27.
Average of 7.27 and 7.29 = 7.28.
Therefore the square root is 7.3 to the nearest tenth.
Answer:
53 lies between 7.2 and 7.3
Step-by-step explanation:
1. Identify perfect squares: 72 = 49 and 82 = 64
2. Estimate between two whole numbers: between 7 and 8
3. Determine the closer whole number: closer to 7 because 53 is closer to 49 than to 64
4. Find the squares of tenths: 7.12= 50.41
7.22= 51.84
7.32= 53.29
7.42= 54.76
