Answer:

Only 16 problems correct

Step-by-step explanation:

Well I thought that since 80% is  4/5 then I should do 20 divided by 5 which will get me 4 and since I'm doing 4/5 I should go all the way up to 80% of 20 which will get me 16.

I'm not making that much sense but

Hope this helps :)

Answer:

2.)   33.33%

3.)   50%

Step-by-step explanation:

There is only one 5 and only one 2. There are 6 sides. The fraction is 2/6, and as a percent it's 33.33%.

There are 3 even numbers and three odd numbers. The chance of getting an even then an odd would be 3/6, or 50%.

Jarvis left out a statement from the proof shown.which statement is best explained by the corresponding angles postulate
Salsk061 [2.6K]
The postulate of the corresponding angles establishes that when a transversal line cuts two parallel lines, the corresponding angles are congruent. These angles are on the same side of the parallel lines and on the same side of the transversal line.

  Then, if we based on this definition and analize the figure attached, we can notice that the angles ∠1 and ∠3 are corresponding angles, so they are congruent. In this case the angle ∠1 is internal and the angle ∠3 is external.

 The answer is: ∠1 and ∠3 are congruent (See the image attached).
