Answer:3,-3
Step-by-step explanation:
difference of 2 squares
(x+3)(x-3)
x+3=0
x-3=0
x=3,-3
The unit rate for the 1st one is: $0.19 / ounce
The unit rate for the 2nd one is: $0.16 / ounce
The 36 ounce box would be the better buy because it is less per ounce than the 24 ounce box
Answer:
The answer is 63.31
Step-by-step explanation:
Answer is 823.2 cu.in.
Reason
For the sphere
We know V=4/3 TT r^3
Radius is 3
V=4/3 (3.14) 3^3
V= 4/3 (3.14) 27
V= 113.1 for each sphere
8 spheres x 113.1 = 904.8 cu.in.
For the cubed shaped box
We know v= length x width x height
V= 12 x 12 x 12
V = 1728 cu.in.
Now we take volume of box and subtract volume of spheres to get space filled by packing beads
1728 - 904.8 = 823.2 cu.in.
