Answer:
114.3
Step-by-step explanation:
If a 70kg person ingests 2L of water per day containing 8 mg/L of dinitrotoluene, the concentration of dinitrotoluene on that person's body is:
The hazard ratio is defined by dividing the intake dosage (C) by the reference dose (RfD)
The hazard ratio is most nearly 114.3.
V + 9 / 3 = 8
v / 3 = -1
v = -1 / 3
Is B (x=2) because y=5x^2 then x=2 then 2^2 because x^2 and it comes out 4.then 5x4=20 then 10 is wrong because it's right 20
Answer:
2 hours
Step-by-step explanation:
Since he gets 59.50 every hour you'll need to see how much 59.50 can go into 110$
So, 110/59.50 = 1.8487395
You can then round this number up.
Since he's paid by the hour he'll need to work 2 hours but he'll still have a bit of money left over
Answer: (-5,1)
Step-by-step explanation:
x=-2y-3
4y-x=9
4y-(-2y-3)=9
4y+2y+3=9
6y+3=9
6y=6
y=1
x=-2y-3
x=-2-3
x=-5
