Answer:
82 in^3
Step-by-step explanation:
3 x 2 x 7 + 2 x 2 x 10 = 82 in^3
Opposite
additive inverse
H=(√3)*a/2 = 41.2
So, a=2*41.2/√3=47.6
The scale model of a building 3 inches tall if the building is 90 feet tall is 2:5
<h3>Scaling of measurement</h3>
Scaling is the way of enlarging or reducing the image of an object.
Given scale model of a building is 3 inches, if the building is 90feet tall, to write the scale;
Convert both measures to same units
Since 1 feet. = 12 in
90 feet = 90/12 in = 7.5 in
Take the ratio
3 : 7.5 = 30: 75
Reduce to lowest term
30: 75 = 2 : 5
Hence the scale model of a building 3 inches tall if the building is 90 feet tall is 2:5
