Answer:
8 gallons
Step-by-step explanation:
Total gas in the car = 14 gallons
Each hour gas usage = 1.5 gallons
Total hours traveled = 4 hours
Left gas after 4 hours
= 14-1.5(4)
=14-6
=8 gallons
Left gas after t hours
=14-1.5t
Hence the answer is after 4 hours, 8 gallons are left after t hour(s) 14-1.5t
<em>*It's debatable that there are 2 answers to this question because of how it's worded*</em>
For the first answer:
There would be 66 books left.
To get this, you need to multiply the original amount (120) by the decimal form of the percentage.
So, to get the decimal form you need to divide by 100, which essentially means you move the decimal 2 places to the left.
55% then becomes .55
So, 120 * .55 = 66
For the second answer:
If the question means that you need to decrease 120 by 55% <em>of 120 </em>then the answer would be 54.
120 - 66 = 54
So, depending on the answer choices and how it's interpreted, do what you will with this information.
All the ones with saving account number are not functions because the
outcome does not depend on the account number. It depends on
the amount in the account and the interest.
Question:
Which statement is true about the polynomial
–3x4y3 + 8xy5 – 3 + 18x3y4 – 3xy5 after it has been fully simplified?
It has 3 terms and a degree of 5.
It has 3 terms and a degree of 7.
It has 4 terms and a degree of 5.
It has 4 terms and a degree of 7.
Answer:
Option D: It has 4 terms and a degree of 7.
Explanation:
The given polynomial is
We need to simplify the polynomial to determine the number of terms and the degree of the polynomial.
Hence, the simplified polynomial is given by
Term of a polynomial:
The term of a polynomial consists of a number multiplied by a variable or it may be a constant.
Thus, the simplified polynomial has 4 terms.
Degree of a polynomial:
The degree of a polynomial is the sum of exponents of the variables in a term.
Thus, the simplified polynomial has a degree of 7.
Hence, the polynomial has 4 terms and a degree of 7.
Therefore, Option D is the correct answer.
