Answer:
- 100 square miles
- 900 square miles
- 9 times as great
Step-by-step explanation:
It seems rather obvious that ...
(1 cm)^2 ⇒ (10 mi)^2 = 100 mi^2 . . . on the first drawing
(1 cm)^2 ⇒ (30 mi)^2 = 900 mi^2 . . . on the second drawing
The area on the second drawing is 900/100 = 9 times as great.
_____
These are the areas represented by 1 square cm on the scale drawing. If the drawing is larger, then the represented area is correspondingly larger. The ratio of represented areas is still 9 times for drawings of the same size.
Answer:
Step-by-step explanation:
We have to write the rule to simplify fractions with negative exponents in the denominator and numerator.
If we have positive exponents, the simplification takes place as following:
The powers of the same base of numerator and denominator are subtracted.
In case of negative exponents, the simplification takes place in the following manner:
The powers of the same base of denominator and numerator are subtracted.
