Explanation:

If the amount of change due to rounding is the same for both numbers, the original difference and the difference of rounded values will be the same. This will always be the case if the hundredths digits are the same to start with.

<u>Example</u>:

A = 0.56 ⇒ C = 0.6

B = 0.66 ⇒ D = 0.7

B - A = 0.66 -0.56 = 0.10

D - C = 0.7 -0.6 = 0.10 . . . . . same as B - A, ∴ Dominic is incorrect.

A photo collage consists of seven equal-sized square photos arranged in a row to form a rectangle. If the total area of the coll

andrezito [222]

Given:

Seven equal-sized square photos arranged in a row to form a rectangle.

Total area of the collage is 567 square inches.

To find:

The length of the collage.

Solution:

Let the side of each square be x inches.

Seven equal-sized square photos arranged in a row to form a rectangle.

So, length of rectangle is 7x and width is x.

Area of rectangle is

$Area=Length\times width$

$567=7x\times x$

$567=7x^2$

$\dfrac{567}{7}=x^2$

$81=x^2$

Taking square root on both sides, we get

$x=\pm \sqrt{81}$

$x=\pm 9$

Side cannot be negative. So, x=9 inches.

Now,

Width = 9 inches

Length = 7(9) = 63 inches

Therefore, the length of the rectangle is 63 inches.
