Answer:
208 km
16 tablets per day
Step-by-step explanation:
Given:
Length of training track run by Jason = 400 m
Number of times Jason ran on the track = 520
Therefore,
The total length covered by Jason = 520 × 400 = 208,000 m
now,
1 Km = 1000 m
thus,
208,000 m =
or
= 208 km
b) Amount of calcium carbonate in a tablet = 500 mg = 0.5 g
Maximum amount of calcium carbonate that can be taken = 8 g
hence,
the maximum number of tablets that she can take
=
=
= 16 tablets per day
Answer:
b=1
Step-by-step explanation:

The initial population at time t = 0 was 0.39 while the size of the bacteria population after 4 hours was 6553600
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let y represent the bacteria population at time t. a represent the initial population at t = 0. Since the doubling period of a bacteria population is 10 minutes, hence:

At time t = 110 minutes, the bacterial population was 800. Hence:

At 4 hours (240 minutes):

The initial population at time t = 0 was 0.39 while the size of the bacteria population after 4 hours was 6553600
