What is the closest perfect square greater than 54
Anna35 [415]

Answer:

64

Step-by-step explanation:

Perfect squares are integers multiplied by themselves.

  • 2 times 2  = 4
  • 3 times 3  = 9
  • 4 times 4  = 15

The closest perfect squares to 54 are 49 (7^2) and 64 (8^2).

49 is less than 54, so that's ruled out.

Therefore, the closest perfect square to 54 that is greater than it is 64.

Find the length of each arc. Round to the nearest tenth.
avanturin [10]

Answer:

arc ≈ 5.5 units

Step-by-step explanation:

The arc of the circle is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × \frac{\frac{\pi }{2} }{2\pi } ( r is the radius )

    = 2π × 3.5 × \frac{1}{4}

    = \frac{7\pi }{4}

    ≈ 5.5 ( to the nearest tenth )

There are 17 camels I want to divide 3 person if the first one belongs 1/2 The second one belongs 1/3 and the third one belongs
Sergio039 [100]

Answer:

  1. 9 camels
  2. 6 camels
  3. 2 camels

Step-by-step explanation:

If I add 1 camel to the herd, the first person can get (1/2)×18 = 9 camels.

The second person gets (1/3)×18 = 6 camels.

The third person gets (1/9)×18 = 2 camels.

The total number of camels distributed is 9+6+2 = 17 camels.

The one remaining is returned to me.

  • 1st person: 9 camels
  • 2nd person: 6 camels
  • 3rd person: 2 camels

_____

<em>Comment on the question</em>

This is a trick question, a joke, a riddle. 17 camels cannot be divided in the given proportions without dividing a camel. The total of camels distributed should be 1/2 +1/3 +1/9 = 17/18 of the herd. Each person actually gets 18/17 of their allotment.
