Answer:
C) x = 1/2 cm
Step-by-step explanation:
Apparently, we're to assume the units of x are centimeters. The volume of the cube is the product of its dimensions:
V = x³ = 1/8
Then the value of x is ...
x = ∛(1/8) = 1/∛8
x = 1/2

<em>Additional comment</em>
It can be useful to memorize the squares and cubes of small integers. The cubes you see most often are ...
1³ = 1; 2³ = 8; 3³ = 27; 4³ = 64; 5³ = 125; 6³ = 216; 7³ = 343
Answer:
A. 
and 
Step-by-step explanation:
Given:
Vertices of triangle RST are 
and 
.
Rotation is 90° about the center O(0,0). The rotation is counter-clockwise as the angle of rotation is positive.
Now, the co-ordinate rule for 90° rotation counter-clockwise is given as:
→ 
and 
values interchange their places with becoming negative when interchanged.
So, 
→ 
→ 
→ 
⇒ → 
Therefore, the image of the vertices are and .
The Answer is D. If you solve the equation, you find that x=0, which means that the answer would be D. Infinitely many.
Y=mx+b
mx=b-y
÷x. ÷x
m=b-y/x
