First find the missing angles. right now you have 30, 60, and 45. that dotted line between 45 and 60 is connected to another line dividing the 360 in half (making it only 180) if its in two parts and part 1 is 60 that makes part 120. you need angle PF though, so add your 120 on to the 30 giving you 150. to check your answer you add up all sides and if it makes 360 then it's right. my answer for angle PF would be 150.
Answer:
1.36 x 10^-3 cm
Explanation:
Area = 50 ft^2 = 46451.5 cm^2
mass = 6 oz = 170.097 g
density = 2.70 g/cm^3
Let t be the thickness of foil in cm.
mass = volume x density
mass = area x thickness x density
170.097 = 46451.5 x t x 2.70
t = 1.36 x 10^-3 cm
Thus, the thickness of aluminium foil is 1.36 x 10^-3 cm.
Answer:
D
Explanation:
Cells are the smallest unit of organizaiton, followed by tissues, organs, organ systems, and then organisms themselves.
Drift velocity is equal to displacement of the moving object per unit time. The SI unit for displacement is meters while that of time is second. Hence the derived SI unit of velocity is meter per second. This also applies to electron mobility which relates to the displacement per unit time of a moving electron
