2x+4.7=77.8
double the unknown number then add 4.7
Answer:
9 inches.
Step-by-step explanation:
Fun question! The length of a space diagonal for a cube is 
Thus, the first cube has a side diagonal of 
The next cube would have a side diagonal of 3
The third cube would have a side diagonal of 
And the fourth cube would have a side diagonal of 9.
Since the fifth cube has a side length equal to the side diagonal of the fourth cube, it should be 9 inches.
if the order mattered it would be 7*6*5 *4*3 = 2520 arrangements
if order didn't matter
7*6*5*4*3*2 divided by (5*4*3*2*2) = 21
The Answer is C 5/6
250/300 reduced and simplified is 5/6
