You're going on a 1211-mile trip, and your car gets about 29 miles per gallon. Gas prices along your route average $3.40. Estima

te the cost of gasoline for this trip by rounding the distance to 1200 miles, the mileage to 30 miles per gallon, and the cost of gas to $3.00 per gallon. Calculate the answer without using estimate and compare the two results. (Round your answers to the nearest cent.)

Answer:

Using the estimate:

The car has to go for 1,200 miles but it consumes a gallon of gasoline for every 30 miles. The number of gallons it will need is therefore:

= 1,200 / 30

= 40 gallons

Each gallon costs $3.00 so the total cost is:

= 40 * 3

= $120

Without using the estimate:

The car has to go for 1,211 miles but it consumes a gallon of gasoline for every 29 miles. The number of gallons it will need is therefore:

= 1,211 / 29

= 41.76 gallons

Each gallon costs $3.40 so the total cost is:

= 41.76 * 3.40

= $‭141.98

<em>Using the estimate provides a lower cost of gasoline for the trip. </em>

Which answer describes the type of sequence? 16, 12, 32, 92, ... neither arithmetic nor geometric geometric arithmetic
Elanso [62]

Answer:

neither arithmetic nor geometric

Step-by-step explanation:

16, 12, 32, 92, ...

For arithmetic , there should be a common difference

16, 12, 32, 92, ...

Lets find the difference of two consecutive terms

12-16 = -4

32 - 12 = 20

92 - 32 = 60

Common difference is not same so it is not arithmetic

For Geometric , there should be a common ratio

16, 12, 32, 92, ...

Lets find the ratio of two consecutive terms

\frac{12}{16} = \frac{3}{4}

\frac{32}{16} = 2

\frac{92}{32} = \frac{23}{8}

Common ratio is not same , so it is not Geometric

So answer is neither arithmetic nor geometric
