Shadi has four bottles. the bottle hold 650 ml,0.38 l , 5020 ml, 0.045 l. Shadi wants to use the bottle that holds closest to 1 by 2 liters which bottle should she use

0.38 l

Step-by-step explanation:

Bottles:

650 ml0.38 l= 380 ml5020 ml0.045 l= 45 ml

Closest to 1/2 l= 500 ml volume? The difference between the given and 500 ml volume:

650 ml- 500 ml= 150 m380 ml- 500 ml= -120 ml5020 ml- 500 ml= 4520 ml45 ml- 500 ml= - 455 ml

The smallest absolute difference in the list above is -120 so the closest one to 1/2 liters is 380 ml= 0.38 l

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
