You travel 10.7 miles (1 way) for work 5 days a week. On weekends you travel 5.8 miles. The last time you filled your tank you put in 17.2 gallons of gas. At the gas station your "Trip A" meter read 389.30. 1. What is your miles per gallon for the car?

2. how much does your gasoline cost per week?

1. 0.0731 miles per gallon

2.  $967.46

Step-by-step explanation:

The I way travel for 5 days to work will cover: 10.7  miles.

A two travel to work and back home will be : 10.7* 2 =21.4 miles

On weekends miles covered = 5.8 miles

Last time the tank was filled with = 17.2 gallons of gas

The Trip A meter read = 389.30 this is the average fuel mileage

This means the trip consumed : 389.30 - 17.2 = 372.1 gallons of gas

Total miles covered are : 21.4 + 5.8 = 27.2 miles

1. Miles per gallon for the car will be;

  372.1 gallons of gas = 27.2 miles

          1 gallon of gas = ?

{27.2 *1} / 372.1 =  0.0731 miles per gallon

2. Cost of  gas per week will be ;

   In the United States :

   1 gallon of gasoline = $2.60

     372.1 gallons of gas = ? $2.60 * 372.1 = $967.46

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
