Answer:

First choice: 58 seconds.

Step-by-step explanation:

27.8 is approximately 28 seconds, because 8 ≥ 5, so the number rounds up.

30.12 is approximately 30 seconds, since 1 < 5.

So, 28 + 30 is 58. Therefore, 27.8 + 30.12 ≈ 58.

Answer:

  a=\sqrt{33}

Step-by-step explanation:

The Pythagorean theorem tells you that the area of the square with side 'a' is the difference of the areas of the other two squares.

  a² = 7² -4²

  a² = 49 -16 = 33

  a = √33
