Is the question how long would the 185 petri dishes last because if so it would be about 15 days
Hope this helped ;)
20 and 10, 20 is 2 times 10 and if you add them together its 30
Step-by-step explanation:
angle XUV+angle XVY+angle YVZ+angle ZVW=180°
43+angle XVY+52°+36°=180°
angle XVY=180-131
angle XVY=49°
Given that the distance between two lines in the measurement instrument is 0.01m, the maximum error should be 0.01m/2 = 0.005 m.
If you do a good work, the real measure is 1.20m +/- 0.005m, this is between 1.195 and 1.205.
