(1) 9*4 - 4c = x
(2) 9*2 +2c = x

∴ 36 - 4c = 18 + 2c
18 - 4c = 2c
9 - 2c = c
9 = 3c
c = 3 mph

Alenkinab [10]

Answer:

Since 1960, under the influence of cognitive psychology, neuroscience, and cognitive neuroscience, our awareness of ourselves and our environment—our consciousness—has reclaimed its place as an important area of research. After initially claiming consciousness as its area of study in the nineteenth century, psychologists had abandoned it in the first half of the twentieth century, turning instead to the study of observable behavior because they believed consciousness was too difficult to study scientifically. A few examples of when someones body goes in auto pilot could be of the following; negative thoughts about yourself that keep popping up, undesirable habits such as nail biting, sitting on social media too often, and always experiencing certain negative feelings.

Estimates of early Native American hunter-gather societies indicated that a person could
kogti [31]

Other assumptions associated with this question are as follows:

  • One person can feed on 1 hen/day for a year
  • 1 hen must east 25 grasshoppers /day
  • the total mass of 1000 grasshoppers is 1kg
  • 600 grasshoppers are needed to feed 1 human per day

Grasshoppers is represented as Gh.

The total amount needed to feed the hen per year is:

  • 25 x 365= 9,125 Gh/Year
  • If expressed in Kg, then it would be 9,125/1000 which is
  • = 9.125Kg/annum.

So if the farmer chose to live on grasshoppers rather than on hens, the calculation is given as follows:

  • (90 kg/1 hour) x (24 hours/1 day) x (1 person/ 600 Gh)

The amount of Grasshoppers required is given as follows;

If the farmer can gather 90 Gh in one hour then,

  • The total amount of Gh per day is 90 x 24 = 2,160
  • the total amount of Gh available in a year is 2160 x 365 = 788,400 Gh/Year
  • If 600 grasshoppers are quired to feed the human per day, then we work backward
  • The total amount of Gh available in a day is 788,400/365. This is equal to 2160 Gh
  • The total amount of people this can feed is given as 2,160/600
  • Which is equal to 3.6 persons.

Since humans or people cannot be divided into fractions like a measure of sugar or a measure of liquid, the answer is best left to the most approximate digit with it 4 Persons.
