The picture shows the footprints of a man walking. The pace length P is the distance between the rear of two consecutive footprints. For men, the formula, n P =140, gives an approximate relationship between n and P where, n = number of steps per minute, and P = pace length in metres. b Bernard knows his pace length is 0.80 meters. The formula applies to Bernard’s walking. Calculate Bernard’s walking speed in meters per minute and in kilometers per hour. Show your working out.

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

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

lol.

it's ok we all do this sometimes.
