over the next 30 years,some estimates place the worlds population going from roughly 7.2 billion people in the world to 10 billi

on in 2050. Currently, global food consumption equals around 3000 kilo-calories per person, per day and as global prosperity increases that number is expected to rise to roughly 3500 kilocalories person per day. Counting no other costs other than the cost of production (and this means costs to transport,land use costs, CO2 production,water use,ect), lets say it costs us 1 pollution unit to produce 1000 kilo-calories of food today. What is the current impact in pollution units per day to feed the planet?

Answer:

Current impact in pollution units per day=21.6 billion pollution units per day

Step-by-step explanation:

1 person consumes 3000 kilo-calories per person

Current population=7.2 billion people

Total calories the entire population produces=(7.2 billion×3000)

1000 kilo-calories causes= 1 pollution unit

To get the impact of the entire population=(7.2 billion×3000)/1000=21.6 billion pollution units per day

aleksklad [387]

Using mathematical operations and unit conversions, the number of beets that Dwight can grow on the 8 acres is <u>3,885 beets</u>.

<h3>What are mathematical operations?</h3>

Mathematical operations include the use of basic math operators to calculate the values of mathematical statements.

The math operators include addition, multiplication, division, subtraction, exponentiation, and modulus.

<h3>Data and Calculations:</h3>

The measurement of the land = 10 acres

The measurement of the house on the land = 2 acres

The remaining space on the land = 8 acres

The number of beets on 1/8 (0.125) hectare = 150 beets

1 hectare = 2.47105 acres

8 acres = 3.23749 hectares (8/2.47105)

If 0.125 hectares = 150 beets

3.23749 hectares = 150/0.125 x 3.23749

= 3,885 beets

Thus, the number of beets that Dwight can grow on the 8 acres is <u>3,885 beets</u>.

A centipede is crawling 6 inches per minute. how long will it take the centipede to travel 1 yard?
Ede4ka [16]
6 minutes, because 1 yd is equivalent to 3 feet, which is equivalent to 36 inches.  If a centipede crawls at 6 inches per minute, you do 6 x 6, which equals 36, and get 6 minutes!
