First step=
we need to find time for i mile
which is
75/3000=1/40
then to find for 4000 miles we multiply that by 4000
which is 1/40x4000
cancel zeros
1/4x400
=100 hours for 4000 miles
I will determine the domain later
Mr Jones typed 40 * 10 = 400 words.
Mrs Gonzales took 400 / 50 = 8 minutes to type same number of words.
Answer:
5
Step-by-step explanation:
The degree of a polynomial equals the highest degree of it's monomials.
The monomials I see are:
6x^5: The degree is 5.
-4x^2: The degree is 2.
2x^3: The degree is 3.
-3 : The degree is 0. (no variable)
x : The degree is 1.
--------------------------------------
The highest degree of the monomials is 5 so that is the degree of our polynomial.
