Answer:
Option B
Step-by-step explanation:
Question 7
1). √14 + 6.2 < 3π - 8.2
Since, 14 is the nearest whole square number to 16
√14 ≈ √16 ≈ 4
Similarly, π ≈ 3.14 ≈ 3
By substituting these approximate values in the inequality,
4 + 6.2 < 3(3) - 8.2
10.2 < 9 - 8.2
10.2 < 0.8
False.
2). [tex]\frac{17}{5}+\sqrt{64}>8+\pi[/tex]
[tex]\frac{17}{5}+8>8+\pi[/tex]
3.4 + 8 > 8 + 3.14
11.4 > 11.14
True.
3). 35 - √40 > 6π
[Since, nearest whole square integer to 40 is 36 and π ≈ 3]
35 - √36 > 6(3)
35 - 6 > 18
29 > 18
True.
Therefore, Option B is the correct option.
