Why is the total cost of fuel when a driver averages 8 miles per gallon..the cost of fuel is .83 cents a gallon..the drivers distance from oban to stranraer is 20 to the nearest 5 cents..choose from the answers below and show your . 18.05/ b. 17.75/ c. 18.10/ d. 17.50/ e. 17.85

The total cost of the petrol is 2.075 cents.

Step-by-step explanation:

The cost of per gallon petrol = 0.83

Drive per gallon = 8 miles

Here, total distance traveled = 20 miles.

So, the total petrol used for 20 miles = (20 / 8) gallons

= 2.5 gallons

Now, cost of petrol per gallon = 0.83 cents

So, total cost of petrol = 0.83 x 2.5  = 2.075 cents

Hence, the total cost of the petrol is 2.075 cents.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
