Answer:
see below
Step-by-step explanation:
The total number of trees is
567+324+156+89+678 =1814
Percent fir = 567/1814 = .312568908=31.26 %
Percent pine = 324/1814 = .178610805=17.86%
Percent larch = 156/1814 =.085997795=8.60%
percent cedar = 89/1814 =.049062845=4.91%
Percent hemlock = 678/1814 = .373759647=37.38%
The total should be 100 %
31.26+17.86+8.60+4.91+37.38=100.01 ( rounding error because we rounded to the hundredths place)
Solve the equation for x. X+48=649*(1/x)

Answer:
0.252
Step-by-step explanation:
<u>0</u><u>.</u><u>2</u><u> </u> ×126
100
0.252
Answer:
We know that the formula to mix chemical solutions is: C1V1 = C2V2
where C represents the concentration of the solute, and V represents volume in milliliters or ml.
In this case, we have:
0.06V1 = 0.15×350
Solving for 'V1' we have:
V1 = (0.15×350)/0.06 = 52.5/0.06 = 875
Therefre I can make 875 mL of a 6% solution by diluting 350 mL of a 15% solution.
