Answer:

1/5

Step-by-step explanation:

Note that this graph goes through (0, 0) and (2/5, 1/2).

Thus, the slope of the graph is m = rise / run = (1/2)/(2/5) = 1/5.

This m = 1/5 is ALSO the constant of proportionality.

Answer:

59 bacteria would there be after 4 hours.

Step-by-step explanation:

Given:

Bacteria in the petri dish = 40

Time taken for the bacteria to be doubled  =17 hours

To Find:

To Find the number bacteria left after 4 hours = ?

Solution:

By using the proportionality,

After 17 hours the number of bacteria will be 80.

Let the number of bacteria after 4 hours be x

then

\frac{80}{17} = \frac{x}{4}

Now by cross multiplication

17 \times x = 80 \times 4

17 x = 320

x=\frac{320}{17}

x= 18. 82

So the number of bacteria after 4 hours will be

= 40 + 18.82

= 58.82

=59
