Answer:370mm^3
Step-by-step explanation:
You would first find the area of the whole rectangle without the hole, so (15)(30)=450
Next find the area of the hole, (8)(10)=80
To find the area you must subtract the area of the hole from the rectangle.
450-80=370
Answer:
12 cm = 21.62 miles
6 cm = 11.04 miles
Step-by-step explanation:
To find the distance, set up a proportion. A proportion is two equal ratios set equal to each other. We form the ratios by using corresponding values. We write a ratio of
and simplify.
We know
. We know the distance on the map is 12 cm and 6 cm whish converts to 4.7 inches and 2.4 inches. We can write
and
We set them equal.
and
To solve each proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

and
