Quantity of gas in the tank with which Lisa started her journey = 11 1/2 gallons
      = 23/2 gallons
Quantity of gas additionally bought by Lisa during her trip = 6 4/5 gallons
      = 34/5 gallons
Quantity of gas still left in the car after Lisa completed her trip = 3 3/10 gallons
   = 33/10 gallons
Then
Quantity of gas used by Lisa during her trip = [(23/2) + (34/5)] - (33/10) gallons
   = [(115 + 68)/10] - (33/10) gallons
   = (183/10) - (33/10) gallons
   = 150/10 gallons
   = 15 gallons
So we can see from the above deduction that Lisa used 15 gallons of gas during her trip. I hope the procedure is simple enough for you to understand.

Answer from: Quest

answer: 28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° = $\frac{ab}{bc}$

but bc = 20 feet.

⇒ tan 55 ° = $\frac{ab}{20}$

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348 ≈ 28.56 feet
