Frank is filling up his gas tank with gas. The cost of gas is $3.50 for every one gallon. Frank’s car takes 11 gallons of gas to fill up. His car is empty and he only has $30. How much money is Frank short to fill up his tank?

8.5

Step-by-step explanation:

3.5 * 11 = 38.5

38.5 - 30 = 8.5

And I dont think the professors in college are doing a very good job if they are asking you this. (unless im wrong)

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

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° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
