Dimensions of the room in cm = 2.54 x 12 by 15 x 2.54 by 2.54 x 8.5 = 30.48 by 38.1 by 21.59
Volume of the room in cubic cm = 30.48 x 38.1 x 21.59 cubic cm = 25,072.21 cubic cm
Given that the density of air at room temperature is

, thus the mass of air in the room = 25,072.21 x 0.00118 = 29.59 g = 0.0296 kg
Given that the lethal dose of HCN is approximately 300 mg HCN per kilogram of air when inhaled, thus the <span>amount of HCN that gives the lethal dose in the small laboratory room is given by 300 x 0.0296 =
8.88 mg.</span>
92.6, you round 5 up because of the 8.
Answer:
x=0.18 repeating
Step-by-step explanation:
Solve the rational equation by combining expressions and isolating the variable x
A = (pi * r^2)/2
A = (3.1416 * (14.3/2)^2)/2
A = 80.3 ft^2
Answer:
7 hot dogs, 4 wings
5 hotdogs, 5 wings
Step-by-step explanation:
4H + 7W 《56
H = 7, W = 4
4(7) + 7(4) = 56《56
H = 5 , W = 5
4(5) + 7(5) = 55《56
