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
1.7 as a fraction is 17/10
1.(7) the 7 in the parentheses represents the number after the decimal, which is in the tenths spot. 10 tenths + 7 tenths = 17/10 <-- our answer.
if the order mattered it would be 7*6*5 *4*3 = 2520 arrangements
if order didn't matter
7*6*5*4*3*2 divided by (5*4*3*2*2) = 21
