Answer:
x=31
Step-by-step explanation:
Let the frequency be 'f' and wavelength be 'w'

, 
w= 100 m and f = 3,000 kilohertz
Plug in the above values to find k
3000 =
To find k, multiply both side by 100
3000(100) = k
k = 300,000
So equation becomes,
w= ? f = 500 kilohertz
500 =
w =
w = 600 m
Answer:
The side length is 2 cm
Step-by-step explanation:
The volume of a cube is s^3
V = s^3
8 = s^3
Take the cube root of each side
8 ^ 1/3 = s^3 ^ 1/3
2 = s
The side length is 2 cm
Let's go ahead and find the volume of a prism, then double the dimensions and see what happens to the volume. Then we can apply it to your volume.
volume of a prism with dimensions 2x2x2
v= 2x2x2 = 8 units^3
Now let's double it
volume of prism with dimensions 4x4x4
v= 4x4x4 = 64 units^3
So we see that by doubling the dimensions we multiply the volume by a factor of 8. Let's do that for your volume, 3.5 m^3
3.5 x 8 = 28 m^3
C, because drawing cards out of the stacks affects the possible cards you can draw.
