Answer:
Step-by-step explanation:
To solve each of these all you have to do is multiply 60kg which is the whole mass of a human body times the percentage so..
Oxygen = (0.65)(60) = 39kg
Carbon = (0.18)(60) = 10.8kg
Hydrogen = (0.10)(60) = 6
Nitrogen = (0.03)(60) = 1.8kg
Calcium = (0.015)(60) = 0.9kg
Phosphorus = (0.01)(60) = 0.6kg
These numbers dont exactly add up to 60 because the percentages gives dont add up to 100%, but this is how to do it.
Answer:
Step-by-step explanation:
15 bags for $20 can be represented with 15/20
so x bags for $4 can be represented with x/4
now if you proportion it out (ricochet), 4x15 is 60, 60 divided by 20 is 3, so you can buy 3 bags of potatoes with $4.
OR
you could do 15/20 is 0.75
0.75 times 4 is 3, so $4 can buy you 3 bags.
