Answer:
FALSE
2.48 is greater than 2.4 because of the 8 at the end
The ratio given says this - 3 puppies : 2 adults = 5 total dogs
You are given (?) puppies : (?) adults = 80 total dogs
In this case, you are trying to find the number of puppies, so you do not need to care about the number of adults. You need to compare the ratio with the actual amount.
Total/puppies = total/puppies
5/3 = 80/(?)
Now, cross multiply.
5(?) = 240
Divide both sides by 5 and you get your answer.
(?) = 48
The domain (input values) of the cosine function is all negative and positive angle measures.
Let the function be f(x) = cos(x)
The domain of cos(x) is -∞ < x < ∞
The range is -1 ≤ f(x) ≤ 1
Hence, domain of cos(x) is all (+) and (-) angle measures.
Same goes with sine function as well
For function f(x) = sin(x)
The domain is -∞ < x < ∞ and range -1 ≤ f(x) ≤ 1
However for f(x) = tan(x) the same is not applicable.
This is a vertical line. Vertical lines are composed by points who share the same x coordinate.
That's why the equation of the line is exactly
, where k is the shared x coordinate.
In your case, the common x coordinate is 3, so the line is 
Answer: C.186
Step-by-step explanation:
1. You know that he read 6 books when he was 6 years old and every year he doubled the number of books he read the previous year.
2. Let's call
the number of book he read each year and
the number of books he read between the ages of 6 and 10, then:
- At 6 years old:

- At 7 years old:

- At 8 years old:

- At 9 years old:
- At 10 years old:
The total books he read between the ages of 6 and 10 is:
