Answer:
The answer to your question is 0.057 ha
Step-by-step explanation:
Data
Kilocalories needed for a person per day = 2450
Kilocalories produced per hectare = 15737000
Process
1.- Calculate the number of kcal needed per a person for a year
2450 kcal ----------------- 1 day
x ----------------- 365 days
x = (365 x 2450) / 1
x = 894250 kcal
2.- Calculate the amount of land needed
15737000 kcal ------------- 1 ha
894250 kcal ------------ x
x = (894250 x 1) / 15737000
x = 0.057 ha
I believe the answer is $45.75.
I hope this helps.

Answer:
1. 10 6/7 2. 8/15
Step-by-step explanation:
1. 6 1/42 + 4 5/6
- First, let's combine the whole numbers. 6 + 4 = 10
- Now we are left with 1/42 + 5/6.
- To add or subtract, the dominators need to be the same. We need to find the least common multiple which here is 42.
1/42 + 5/6(7)
1/42 + 35/42
= 36/42
= 6/7
- All we have to do is combine both numbers.
10 6/7
2. 13/15 - 1/3(5)
13/15 - 5/15
8/15
