Answer:
Option (2)
Step-by-step explanation:
Volume of a prism A (preimage) = 27 cubic units
Factor of dilation of the sides of this prism (image) = 
Volume scale factor of these prisms = 
Since, Volume scale factor = (Scale factor of dilation of the sides)³
= 
= 
Now from the formula of volume scale factor,


Volume of the image prism =
= 3 cubic units
Therefore, Option (2) will be the answer.
Given:
The symbols
.
To find:
The correct name for the given group of symbols.
Solution:
We know that,
Equality symbols is
.
Inequalities symbols are
.
Operational signs are
.
Radical signs is
.
It means, the symbols
are called inequalities symbols.
Therefore, the correct option is B.
I think it would be b as 12x3=36 and then 36/3=12 I might be wrong tho
The area of the triangle is (1/2)(DE)^2*tan(60°) = (1/2)*2*√3 = √3.
Selection C is appropriate.
