Step-by-step explanation:
the box is
9 in × 3.5 in × 4.5 in = 141.75 in³
each block is
0.5 in × 0.5 in × 0.5 in = 0.125 in³ (1/8 in³)
so, we can fit
141.75 / 0.125 = 1134
blocks into the box.
and they fit neatly, as the dimensions of the box and the cubes allow a tight packing without any empty left over space in the box.
Answer: bn= 150*3^(n-1)( bn is a quantity of bacteria in generation n)
Step-by-step explanation:
It looks like geometrical sequence, each next generation is three times greater than previous one. So the r of this sequence is 3.
The first generation has 150 representatives, so b1=150
The formula of geometrical sequence is bn=b1*r^(n-1)
(in our case bn is a quantity of bacteria in generation n)
so bn= 150*3^(n-1)( bn is a quantity of bacteria in generation n)
