Answer:
a. 4r² b. 2r c. 6 cm
Step-by-step explanation:
The surface area A of the cube is A = 24r². We know that the surface area, A of a cube also equals A = 6L² where L is the length of its side.
Now, equating both expressions, 6L² = 24r²
dividing both sides by 6, we have
6L²/6 = 24r²/6
L² = 4r². Since the area of one face is L², the polynomial that determines the area of one face is A' = 4r².
b. Since L² = 4r² the rea of one face of the cube, taking square roots of both sides, we have
√L² = √4r²
L = 2r
So, the polynomial that represents the length of an edge of the cube is L = 2r
c. The length of an edge of the cube is L = 2r. When r = 3 cm.
L = 2r = 2 × 3 cm = 6 cm
So, the length of an edge of the cube is 6 cm.
Answer:
If the goal is to break the vases: 3/20 = 15.0% or 0.15
If the goal is to not break the vases: 17/20 = 85.0% or 0.85
Answer:
Replace x with −x.
f(x) = 3(2)−x is not correct because the y-intercept is (0, 3).
the answer is B

Answer:
30
Step-by-step explanation:
So to do this you would set up the equation
than you would add 6 to both sides so you would get
than you would divide 3 from both sides so
and that is the final answer which is correct
The answer is b bc the area of one cube is 57.76 so you multiply that by six bc there are six cubes. Once u do that you get 346.56 as the answer
