The area of a square floor on a scale drawing is 81 square centimeters, and the scale drawing is 1 centimeter:2 ft.
so the original area is
A = 81 sq cm ( 2 ft / 1 cm)^2a = 324 sq ft
so the ratio of the ratio the area in the drawing to the actual area is:
r = 81 sq cm / 324 sq ftr = 1 sq cm / 4 sq ft1 sq cm : 4 sq ft

Use a graphic organizer to compare and contrast similar and congruent figures
Anika [276]
Similar figures are figures of the same shape but different (or same) size.
Thus, they look the same, but one is bigger than the other by a scale factor.

Congruent figures are figures of the same shape AND same size.
They can be mapped onto each other using any type of transformation (besides dilations).

Similar figures can be dilated.

Write $\frac{99}{100}\cdot(0.\overline{4})$ as a fully simplified fraction.
Oksi-84 [34.3K]

Answer:

  • \frac{11}{25}

Explanation:

The expression that must be rewritten as a fully simplified fraction is:

  • \frac{99}{100}\cdot(0.\overline{4})

You must, first, convert     0.\overline{4}    as a fraction.

The line over the decimal 4 means that the digit 4 repeats indefinetly.

To find the fraction that represents this number you follow this procedure:

F=0.\overline 4\\ \\ 10F=4.\overline 4\\ \\ 10F-F=4\\ \\ 9F=4\\ \\ F=4/9

Now, you can mutiply both fractions:

\frac{99}{100}.\frac{4}{9}=\frac{99\times 4}{100\times9}=\frac{11}{25}
