Answer:
Dilation.
Step-by-step explanation:
From the given picture , it can be seen that the size of trapezoid P'Q'R'S' is decreased from trapezoid PQRS .
Reflection , rotation and translation are rigid motions that produces congruent images and do not change the size of the shapes.
But dilation is not a rigid motion because it changes the size of the shape by using a scale factor.
Hence, the transformation maps trapezoid PQRS onto trapezoid P'Q'R'S' is "Dilation".
Answer:
x=2.11872822
Step-by-step explanation:
The area for one side is S^2 where S is the length of one side.
The area for one side = 1/2^2 = 1/4 square foot.
A cube has 6 sides. Total surface are = 1/4 x 6 = 1 1/2 square feet.
Volume of a cube is S^3
1/4^3 = 1/64 cubic foot.
Answer:
7/11
Step-by-step explanation:
Let d represent the original denominator. Then the original numerator is ...
2d-15
The new numerator is ...
(2d-15) +5
and the new denominator is ...
d+7
The ratio of these is 2/3, so we have ...
The original fraction is 7/11.
