Find the unit rate:
1/4 yd 1(5)
---------- = -------- = 5/4 yards, or 1 1/4 yards, in one hour. This is 1.25 yards.
1/5 hr 4(1)
90 degrees converted to radians is pi/2 or π/2 radians.
<em>Answer:</em> ΔTAU ≈ ΔUAV ≈ ΔTUV
<em>Step-by-step explanation:</em>
I'm not really sure what "work" you really need; this is a problem that can be solved easily by simply looking at the triangles and seeing which sides have the same ratio of distances for each side.
Best of luck with your assignment. :) Feel free to give me Brainliest if you feel this helped. Have a good day.
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>
