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.

answer: c i think

step-by-step explanation:

96 39 cause 135 -96=39 im smart (i used a calculater)

answer: list the statements and i will follow up!

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
