C. sounds like the most reasonable answer to the question.<span />
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.
Line a and b are parallel
Answer:
mp=4500
let discount %be x
sp=mp-discount %of mp=4500-x/100×4500=4500-45x
Step-by-step explanation:
sp with 10%vat=sp+vat%of sp
4400=4500-45x+10/100(4500-45x)
4400-4500=(-450x+(4500-45x)/10
-1000=(-450x+(4500-45x)
-1000-4500=-495x
495x=5500
x=5500/495=11.11%
B. Deposit means she added money to her account so you would add 175 and 180 to 685 (giving you 1040). Withdrawal means she took money out of her account so you would subtract 240, 140, and 350 from 1040 giving you your answer of $310 :)
