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
Explanation:
The two equations are and
To determine why the two equations are equivalent, let us solve the equation.
Consider solving the equation , we get,
Adding 13 on both sides, we get,
Consider solving the equation , we get,
Adding 37 on both sides, we get,
Thus, when solving both the equations, the value of H is equal.
Since, the value of H is equal, the equations and
are equivalent equations.
The meaning of the solution:
A value of a variable which makes the equation true is called a solution.
Here the value of the variable H is 197. Let us substitute the value in the equations and
to determine whether it makes the equation true.
Let us substitute in
, we get,
Hence, is true solution.
Also, let us substitute in
, we get,
Hence, is true solution.
Step-by-step explanation:
hihi, so this is a classic interest rate problem. It's not too bad if you know your properties of e and ln. After establishing the base equation you can divide by 100 then take the natural log of both sides to "get rid" of the e and finally end it by dividing by 10 to isolate r.
