Answer:
x = 7cm
Step-by-step explanation:

Answer:
0.4 ft
Step-by-step explanation:
It can be convenient to let a spreadsheet compute the values for you. Here, we have written an explicit formula for the height of the n-th bounce:
h = 5.5×0.64^(n-1)
We have written the formula this way because we are given the height of the first bounce, not the starting height. Each bounce multiplies the height by a factor of 0.64. Then the 7th bounce will have a height of ...
h = 5.5×0.64^6 ≈ 0.378 ≈ 0.4 . . . . feet
Answer:
No there is no solution
Step-by-step explanation:
X cannot be found no matter how you try to solve the simultaneous equation so therefore y can also not be found.
Answer: The perimeter is 
Step-by-step explanation:
1. By definition, the formula for calculate the surface area of a cube is:

Where s is the lenght of any edge of the cube.
2. You know that the surface area of the cube of the problem is
, therefore the lenght of each edge of the cube is:

3. Each face of the cube is a square, therefore the perimeter of one face is:
