Answer:
The answer is " E'F' and EF are equal in length".
Step-by-step explanation:
By rotating that through some degree, a revolution is some kind of rigid transformation, which creates an image of the very same shape and size. There will be two main properties of the rotation:
- Preservation of rotating scale (including sides and angles).
- The lines connecting the rotation center to the pre-image and the corresponding image point are of equal length.
In each line, the segment is rotated counterclockwise 180 degrees around the origin to form E'F, that's why the above given choice is correct.

Answer:
343π/6 cm³ ≈ 179.6 cm³
Step-by-step explanation:
The formula for the volume of a sphere is one of the volume formulas worth memorizing. It is ...
V = (4/3)πr³
For r = 3.5 cm, the volume is ...
V = (4/3)π(3.5 cm)³ = 343π/6 cm³ ≈ 179.6 cm³
The volume of air in the balloon is about 179.6 cm³.
Answer:
False
Step-by-step explanation:
<span> 0.81x - 0.45 is subtracted from 3.28x + 1.4
</span>3.28x + 1.4 - (0.81x - 0.45) = 3.28x + 14 - 0.81x + 0.45
= (3.28x - 0.81x) + ( 14 +0.45)
= 4.09x + 14.45
