A grandfather clock has a pendulum that swings back and forth. The time t in seconds it takes the pendulum to complete one full cycle is given by the formula t = 0.2√, where p is the length of the pendulum in centimeters. How long is a full cycle if the pendulum is 22 cm long? Round your answer to the nearest tenth of a second.

Step-by-step explanation:

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
