Answer:
log(2)
Step-by-step explanation:
In order to combine log(10) and log(5), you need to look at the sign that's combining them. In this example, it is a subtraction sign. When two logs are being subtracting from each other, it's the same as dividing the two. You would rewrite it like this:
log(10/5)
You would then solve 10/5, and get 2. You would rewrite the log as:
log(2)
Answer:
28 rabbits
Step-by-step explanation:
From the statement, you can write the following:
d+c+r= 126
d=dogs
c= cats
r= rabits
Then, you have that there are 13 cats and that three fourths of the remaining animals are dogs:
c=13
d=(126-13)*(3/4)= 113*(3/4)= 85
Now, you can isolate r, to find the number of rabbits:
r=126-d-c
r= 126-85-13
r= 28
According to this, the are 28 rabbits.
