Suppose that the demand Q^Dand supply Q^Sfor maize meal in Kimberley is given by p=120-0.7Q^Dand p=3+0.2Q^S where the quantity i
bixtya [17]

Answer:

  20 rands/kg

  130,000 kg

Step-by-step explanation:

The equilibrium quantity and price are the solution to the system of equations ...

  p = 120 -0.7q

  p = 3 + 0.2q

Setting these equal, we get ...

  0.2q +3 = p = -0.7q +120

  0.9q = 117 . . . . . . . add 0.7q-3 to both sides

  q = 117/0.9 = 130

  p = 3 +0.2·130 = 29

The equilibrium price of maize meal is 29 rands per kg; the market equilibrium quantity is 130,000 kg.

During strenuous work a human body generates about 2,400 BTUs of body heat per hour. If 7 bodybuilders are in a gym that is 20 f
Ede4ka [16]
By doing dimensional analysis, we can easily calculate for what is being asked here. We do as follows:

Given:
Energy per time = 2400 BTU/hr
time period = 3 hrs
number of subjects = 7
Measurement of the weights = <span>20 ft × 25 ft × 12 ft

The energy produced for 3 hours would be:

2400 BTU/hr ( 3hr) = 7200 BTU
Volume of each weight = </span><span>20 ft × 25 ft × 12 ft = 6000 ft^3

Energy per volume = 7200 / 6000 = 1.2 BTU/ft^3

However, we have 7 bodybuilders producing this amount therefore,

Total energy produced = 7 (1.2 BTU/ft^3) = 8.4 BTU/ft^3</span>
