Answer: $\displaystyle\ \Large \boldsymbol{ -\frac{5\cdot \sqrt{2} }{4}}$

Step-by-step explanation: $\displaystyle\ \Large \boldsymbol{} \frac{5}{\!\!\sqrt{2} } +\frac{9}{\!\!\sqrt{8} } -2\sqrt{50} +\sqrt{32} =\frac{1}{\!\!\sqrt{2} } \bigg(5+\frac{9}{\sqrt{4} } \bigg)+\sqrt{2} (\sqrt{16} -2\sqrt{25} ) \\\\\\\\\frac{1}{\sqrt{2} } (5+4,5)+\sqrt{2} (4-10)=\frac{9,5}{\sqrt{2} } -6\sqrt{2} =\frac{9,5-12}{\sqrt{2} } = \\\\\\-\frac{5\cdot \sqrt{2} }{4}$

An average person in the country needs 2,450 kilocalories / day of food to meet their full nutritional needs. The average number

sesenic [268]

Answer:

Amount of land = 0.056 hectares

Step-by-step explanation: Given that

An average person in the country needs 2,450 kilocalories / day. That is

A person in a day takes 2450 kilocalories

The average number of kcal per hectare(ha) produced from available food in the country is 15,737,000 kcal/ha.

So in one day per person, we have

15737000 = 2450/hec

Hectare = 2450/15737000

Hectare = 1.5568 × 10 -4

The amount of land that would be needed to produce enough kilocalories to feed a person for one year in this developing country will be

Calculated hectare × 365.25

Hectare = 1.5568 × 10 -4 × 365.25

Amount of land = 0.056 hectares
