Answer 16 cubic cm (cm^3)
Volume of a cube is L x W x H
Since the cube has equal sides of 4 cm
4 x 4 x 4 = 64 total volume of cube
Now we take 25% of the cubes total volume to find the portion filled with sand
25% x 64 = 16 cubic cm
Answer:
15) f = 18
3f = 54
6f = 108
16) k = 69
Step-by-step explanation:
15)
3f + 6f + f = 180
10f= 180
f = 18
16)
42 + k + k = 180
42 + 2k = 180
2k = 138
k = 69
Answer:
infinite number
Step-by-step explanation:
Carry out the multiplication indicated here:
5x + 3(x-5) = 6x + 2x -15 => 5x + 3x - 15 = 6x + 2x -15
Now combine the x terms: We get 8x - 15 = 8x - 15, or -15 = -15.
This last result is always true, so this equation has an infinite number of solutions.
Answer:
y intercept = 5
Step-by-step explanation:
In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.
