<em>Total number of coin that George has
16 + 28 + 32 + 4 = 80 coins
total number of coins sold by George
= 15% of 80
= 15/100 X 80
= 12 coins (ans)</em>
There is a total of 16+11+9+15+8+20 = 79 blocks. Since she is replacing the block each time it is drawn, the probability that she draws an orange block is always the same (10 draws or 500 draws). Since 20 of the blocks are orange, the probability would be
20/79 or
D) 0.25
You would add 5 and 1.2 which gives you 6.2 then you add negative 3.6 which then gives you 3.6.
64 = 4³
-216 = (-6)³
.008 = 0.2³ . . . . . . 1000 = 10³, 8 = 2³. This is 8/1000, so the cube of 2/10
1/64 = (1/4)³ . . . . . . the inverse of the first number
4 17/27 = 125/27 = (5/3)³

You can see that it would be helpful to have memorized the cubes of small integers.
