Answer:

5 generations

Step-by-step explanation:

Data provided in the question:

Number of bacteria at the beginning of a time interval , B = 4

Number of bacteria at the end of the time interval, b = 128

Now,

The relation between the bacteria at the beginning, bacteria at the end and the number of generations (n) is given as:

b = B × 2ⁿ

Therefore,

on substituting the respective values, we get

128 = 4 × 2ⁿ

or

2ⁿ = 32

or

2ⁿ = 2⁵

or

n = 5

hence,

5 generations

What’s the equation.?
Stella [2.4K]

Answer:

See below

Step-by-step explanation:

You know that he spent 1/3 of his earnings, and then 1/4. After this, he has $28.90. You can write the equation like this:

1/4(x * 1/3) = $28.90.

If you need to solve it:

1/4 * 1/3x = 28.90

1/12x = 28.90

x = 346.80

A stack of one hundred fifty cards is placed next to a ruler, and the height of the stack is measured to be 5/8 inches.
DaniilM [7]
Divide 5/8 by 150, to see how thick each is, that'll give you 150 even pieces that add up to 5/8

\bf \cfrac{\frac{5}{8}}{150}\implies \cfrac{\frac{5}{8}}{\frac{150}{1}}\implies \cfrac{5}{8}\cdot \cfrac{1}{150}\implies \cfrac{1}{8\cdot 30}\implies \cfrac{1}{240}
