8.A: What two perfect squares is 28 between?
8.B: Use your knowledge of perfect squares to approximate √28.
8.C: What two perfect squares is 80 between?
8.D: Use your knowledge of perfect squares to approximate √80.
8.A: 28 is between 25 and 36, which are the perfect squares of 5 and 6, respectively.
8.B: √28 is between √25 and √36, which are 5 and 6, respectively. So, we can approximate √28 as 5.29 (since 28 is closer to 25 than 36).
8.C: 80 is between 64 and 81, which are the perfect squares of 8 and 9, respectively.
8.D: √80 is between √64 and √81, which are 8 and 9, respectively. So, we can approximate √80 as 8.94 (since 80 is closer to 81 than 64).
thank you but do you think you can round the answers from 8b and 8d.
Sure! Rounded to the nearest hundredth, the answers for 8b and 8d would be:
8.B: √28 ≈ 5.29
8.D: √80 ≈ 8.94
round to the nearest whole
Sure! Rounded to the nearest whole number, the answers for 8b and 8d would be:
8.B: √28 ≈ 5
8.D: √80 ≈ 9
To find the perfect squares that a given number is between, you can start by finding the square root of that number. The square root will give you the value between which the number lies.
For question 8.A, to find the two perfect squares that 28 is between, we need to find the square root of 28. Let's approximate it:
√28 is approximately 5.29 (rounded to two decimal places).
So, 28 is between the perfect squares of 5^2 (25) and 6^2 (36). Therefore, it is between 25 and 36.
Now, for question 8.B, to approximate the square root of 28, we can use our knowledge of perfect squares that we just found. Since 28 is between 25 and 36, we know that the square root of 28 is approximately between 5 and 6.
For question 8.C, to find the two perfect squares that 80 is between, we need to find the square root of 80. Let's approximate it:
√80 is approximately 8.94 (rounded to two decimal places).
So, 80 is between the perfect squares of 8^2 (64) and 9^2 (81). Therefore, it is between 64 and 81.
Finally, for question 8.D, to approximate the square root of 80, we can use our knowledge of perfect squares that we just found. Since 80 is between 64 and 81, we know that the square root of 80 is approximately between 8 and 9.
