Answer:
= 124 ft
Step-by-step explanation:
Perimeter of a rectangle is
P = 2(l+w)
We know the length is 13 and the width is 49
P = 2(13+49)
=2(62)
= 124 ft
Answer:
a) 16.82 mg
b) 24 days
Step-by-step explanation:
Formula for exponential growth is given as:

Where A is the final population
is the initial population
b is the growth factor
c is the time taken for the growth 'b'
t is the amount of time
Here, We are given the following:
= 5 mg
b = 2 (Given because it doubles)
c = 4 days
a) A = ?
Using the formula:

b) Given
A = 320 mg
t = ?
Using the above formula again:

So, the answers are:
a) 16.82 mg
b) 24 days
Answer:
0.18181818181
Step-by-step explanation:
To solve for w, you would take 9 and subtract that from the 69. after that you end up with 60=5w to find w, divide both sides by 5. 60 divided by 5 is 12, giving you your answer .
