Answer:

23 × 23

Reasoning:

A prefect square is a number times itself

The product of the perfect square can therefore be a sqaure root

23 × 23= 529

Then if we square root 529 it would always be a whole number (23)

A rectangle has an area of 24 square inches. The rectangle is reduced by a scale factor of 1/2 . What is the area of the new rectangle?

Answers

Considering the scale factor of the reduction, it is found that the area of the new rectangle is of 6 square inches.

What is the area of a rectangle?


The area of a rectangle of length l and width w is given by:

[tex]A = lw[/tex]

In this problem, the rectangle is reduced by a scale factor of 1/2, hence:

[tex]l \rightarrow \frac{l}{2}, w \rightarrow \frac{w}{2}[/tex]

Then, the area is given by:

[tex]A = lw = \frac{l}{2} \times \frac{w}{2} = \frac{lw}{4}[/tex]

A rectangle has an area of 24 square inches, hence:

[tex]lw = 24[/tex]

Thus:

[tex]A = \frac{lw}{4} = \frac{24}{4} = 6[/tex]

The area of the new rectangle is of 6 square inches.

Answers

Answer:

In common scientific notation, any nonzero quantity can be expressed in two parts: sufficient whose absolute value is greater than or equal to 1 but less than 10, and a power of 10 by which the coefficient is multiplied. In some writings, the coefficients are closer to zero by one order of magnitude. In this scheme, any nonzero quantity is expressed in two parts: a coefficient whose absolute value is greater than or equal to 0.1 but less than 1, and a power of 10 by which the coefficient is multiplied. The quantity zero is denoted as 0 unless precision is demanded, in which case the requisite number of significant digits are written out
