Answer:

We can divide both sides by 20 and we got:

Now we can appply natural log on both sides and we got:

Now we can divide both sides of the equation by 10 and we got:

So then the aproximate value of k is 0.30986 and rounded would be 0.31
Step-by-step explanation:
We have the following two expression:


We know that the two populations were equal 10 years after the start of the study, so then we can create the following equation:

We can divide both sides by 20 and we got:

Now we can appply natural log on both sides and we got:

Now we can divide both sides of the equation by 10 and we got:

So then the aproximate value of k is 0.30986 and rounded would be 0.31
Answer:
x = 84°
Step-by-step explanation:
180 - 143 = 37
37 + 59 = 96
180 - 96 = 84°
The answer to the equation is x=4.5
72 miles=1 gallon
Step by step Explanation:
Divide 1080 by 15 and divide 15 by 15. You get 72 and one.
