Want to use some of the algebra rules of log's:
log(a)-log(b)= log(a/b),
so log(P/N) - log(M/N) = log( P/N:M/N) = log(P/M),
Then: 8-5 = log(P/M), log(P/M)=3.
If log here means natural logarithm (base e), then P/M = e^3,
If log here means basis 10, decimal logarithm, then P/M = 10^3 = 1000.
Answer:
The translation of the question is: " Angelfish are 4/7 and gladiolus 5/9 of all fish in a certain aquarium. Are there more angelfish or gladiolus in this aquarium?
The answer is: there are more angelfish.
Explanation:
You have the fraction for both angelfish and gladioulus in a certain aquarium, so you need to compare those fractions to conclude which fraction is greater.
To compare fractions you can divide one by the other. Whether the quotient (the result of the division) is greater than, equal than, or less than one will tell which fraction is greater than the other.
- If fraction 1 / fraction 2 > 1 ⇒ fraction 1 is greater than fration 2
- If fraction 1 / fraction 2 = 1 ⇒ fraction 1 is equal to fraction 2
- If fraction 1 / fraction 2 < 1 ⇒ fraction 1 is less than fraction 2.
Now, lets compare the fish's fractions:

Then, you conclude that 4/7 is greater than 5/9, and thus the fraction of angelfish is greater than the fraction of gladioulus: there are more angelfish in the aquarium.
Answer:
$200
Step-by-step explanation:
125/5=25
25 x 8=200
32 cause it’s 32 it be 32 boo
A= 3400t + 600 | given formula
21000= 3400t + 600 | substitute the altitude into the formula
20400 = 3400 | subtract 600 from both sides
6 = t | divide both sides by 3400
