Ah clever. So you need two formulas.
1) Volume of the marble.
4(pi)r^3/3
= 4(pi)(1.4)^3/3
<span>= 11.49 (approx)
</span>
2) Formula for density.
D = M / V
= 9 / 11.49
= 0.78
0.78 < 1
Therefore the marble will float.
PEMDAS
you would do left to right and look for multiplication or division.
64/2= 31
31*16=512
Rolling a 2 has a probability of 1/6
Odd number probability is 1/2
1/6*1/2=1/12
Answer:
8 and 4 = 8
8 and 10 = 40
Step-by-step explanation:
The least common multiple is the smallest value that both numbers equal when you look at their multiples.
The multiples of 8 are 8, 16, 24, 32, 40...
The multiples of 4 are 4, 8, 12, 16, 20, 24, 28, 32...
The multiples of 10 are 10, 20, 30, 40...
The first multiple 8 and 4 have in common is 8.
The first multiple 8 and 10 have in common is 40.
