Answer:

  • The given number is irrational.

Step-by-step explanation:

It is known that \sqrt{2} is irrational.

Given number can be converted as:

  • 5\sqrt{32} =
  • 5\sqrt{16*2} =
  • 5\sqrt{16}*\sqrt{2}  =
  • 5*4*\sqrt{2}  =
  • 20\sqrt{2}

Since \sqrt{2} is irrational, 20\sqrt{2} is also irrational (<em>the product of an irrational number and a rational number is irrational</em>), so the given number is irrational.

Vinil7 [7]

Answer  

Find out the  percent error in Annie's estimate .

To prove

Formula

Percentage\ error = \frac{error\times 100}{exact\ value}

As  error = approx value -  exact value

As given

Annie estimates that the height of a bookcase is 78.25 in.

The actual height is 75.50 in.

approx value = 78.25 in.

actual value = 75.50 in.

error = 78 .25 - 75 .50

        = 2.75

put in the formula

Percentage\ error = \frac{2.75\times 100}{75.50}

Percentage\ error = \frac{27500}{7550}

Percentage error = 3.64 % (approx)

Therefore the Percentage error be 3.64 % (approx).
