Mr. And Mrs. Fink drove 462 miles on 21 gallons of fuel. Conrad drove 456 miles on 12 gallons of fuel. How many more miles per gallon does Conrad's car get than Mr and Mrs Finks car?

Conrad's car gets 16 miles per gallon more than Mr and Mrs Finks car.

Step-by-step explanation:

Miles per gallon = total miles driven/number of gallons of fuel used

Mr. And Mrs. Fink drove 462 miles on 21 gallons of fuel. It means that the number of miles that they drove per gallon of fuel is

462/21 = 22 miles per gallon

Conrad drove 456 miles on 12 gallons of fuel. It means that the number of miles that Conrad drove per gallon of fuel is

456/12 = 38 miles per gallon

The difference in the number of miles per gallon that they drove is

38 - 22 = 16 miles per gallon

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
