Answer:
65.7 mg/l.
Step-by-step explanation:
Answer:
A. 65.7 mg/l.
B. iv. No. The average chlorine compound concentration (mg/l) is too high.
Step-by-step explanation:
Given:
Outflow = 36%
= 36 l in 100 l of wetland
Seepage = 47%
= 47 l in 100 l of wetland
Evaporates = 8%
= 8 l in 100 l of wetland
Water volume = 9%
= 36 l in 100 l of wetland
Outflow = 53.6 mg/l
Seepage = 73.9mg/l
Remaining due to evaporation = 57.0mg/l
Water volume = 74.0 mg/l
Concentration of Chlorine compounds:
Outflow = 36/100 * 53.6
= 19.3 mg/l of outflow chlorine in the wetlands.
Seepage = 47/100 * 73.9
= 34.73 mg/l of seepage chlorine in the wetlands.
Evaporates = 8/100 * 57
= 4.56 mg/l of evaporates chlorine in the wetlands.
Water volume = 9/100 * 74
= 6.66 mg/l of outflow chlorine in the wetlands.
Weighted average concentration of chlorine compounds in 100 l of wetland = total(X*W)/totalW
Where,
Total w = 0.36 + 0.47 + 0.08 + 0.09
= 1
Total X*W = 19.3 + 34.73 + 4.56 + 6.66
= 65.65/1
= 65.7 mg/l.

Answer:
D. The oldest is 92 youngest 49
Step-by-step explanation:
we can get the answer by pairing each of the values on the left hand side that is these values 4 5 6 7 9 with values on the right.
the first age from the top row is 49 the second is 49
from the second row it is 50 50 51 51 52 5 59
from the 3rd row 61 62 63 64 64 65 6
from the forth row t s 71 72 73 73 74 75 7
from the fifth row it is 80 81 83 87
from the sxth row it is 91 92.
each of the numbers have just written out represents age. the oldest age there is 92 whle the youngest s 49. It is simply each number under attorney paired wth stem to make a number.
