While in europe, if you drive 107 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per lite

Answer:
The money spend on gas in one week = 46.13 Euro
The money spend on gas in one week = $58.12
Step-by-step explanation:
1 week = 7 days
You drive 107 km per day.
Kilometer driven for 7 days = 7 *107 = 749 kilometers.
Now let's convert kilometers to miles.
1 mile = 1.60934 kilometers
We have to divide 749 km by 1.60934.
So, 749 km = 465.41 miles.
Car mileage is 42 miles / gallon.
We need to find the number of gallons of gas needed to travel 465.41 miles.
So, we have to divide 465.41 miles by 42.
The number of gallons of gasoline needed =
cost of 1 .10 Euros per liter.
Now we have to convert 11.08 gallons to liters.
1 gallon = 3.78541 liters.
So we have to multiply 11.08 by 3.78541
11.08 gallons = 41.94 liters.
Now to find the cost, we need to multiply 41.94 liters by 1.10 Euro.
The money spend on gas in one week = 46.13 Euro
To convert the cost in dollars.
1 euro = 1.26
We need to multiply 46.13 by 1.26
The money spend on gas in one week = $58.12

Answer and Step-by-step explanation: The definition of polynomial is "poly" meaning many and Nominal, which means terms. So, <u>Polynomial</u> is an expression of constants, variables, exponents that are combined using mathematical operators: addition, subtraction, multiplication and division.
However, there are exceptions:
- Polynomial don't have negative exponent;
- Polynomial cannot be divided by a variable;
- Variable cannot be inside a radical;
The <u>degree</u> <u>of</u> <u>a</u> <u>polynomial</u> is the highest exponent of that variable. For example for polynomial , the degree is 5.
Polynomials have 3 different types:
- monomial: only has one term;
- binomial: has 2 terms;
- trinomial: has 3 terms;
Now, analysing each expression given by the alternatives above:
1. It is a polynomial of degree 3 and trinomial.
2. It is a polynomial of degree 2 and trinomial.
3. Yes, its a polynomial of degree 2 and monomial.
4. It is not a polynomial because it is divided by a variable.
5. A polynomial of degree 5 and it's a binomial.
6. It is not a polynomial due to the exponent being negative.
