Answer:
2 × 10 g
Step-by-step explanation:
The lethal dose 50 (LD50) of Coumarin is 293 mg/kg body mass. The amount of Coumarin that a 70 kg student would have to ingest to reach the LD50 is:
70 kg body mass × (293 mg/kg body mass) = 20510 mg
1 gram is equal to 1000 milligrams. The mass (in grams) corresponding to 20510 milligrams is:
20510 mg × (1 g/ 1000 mg) = 20.51 g ≈ 2 × 10 g
Answer:
The answer is (-4,9)
Step-by-step explanation:
When you reflect across y=-x the x and y coordinates switch places and change signs.
Answer:
x is 7.5 so the answer is D
Step-by-step explanation:
Since the triangles are similar, you can flip the 1st one to match the 2nd.
Now you can write
16/12=10/x
(the 9 is irrelevant)
now cross multiply to solve for x
12x10=120
120/16=7.5
x is 7.5
