320 students. Because you have to divide 384 by 6 which will give you 64 which is the number for the students that chose art and then subtract that from the total students which are 384 and you'll get 320 as your answer for the student that didn't pick art.
<em>Answer:</em>
<em>$5 for 8 pens</em>
<em></em>
<em>Step-by-step explanation:</em>
<em>0.625 times 8= 5 dollars</em>
<em>0.625 times 50= 31.25</em>
<em>which is way cheaper</em>
Solution: We are given:
The area covered by five great lakes in United States
square miles.
The area covered by the smallest of the great lakes, Lake Ontario
square miles.
The fraction of the area of Ontario lake to the total area of all the great lakes is:


Therefore, the simplest form of fraction is 

The missing statement in the proof is ∠1 ≅ ∠4.
Solution:
(1) Given ∠1 ≅ ∠2
(2) ∠1 and ∠4 are vertical angles.
<u>Vertical angle theorem:
</u>
If two angles are vertically opposite then they are congruent.
By vertical angle theorem,
⇒ ∠1 ≅ ∠4
(3) <u>Transitive property of congruence:</u>
If A = B and B = C, then A = C.
From (1) and (2), ∠2 ≅ ∠4.
(4) If two lines and a transversal form congruent corresponding angles, then the lines are parallel.
Therefore line a || line b.
⇒ a || b.
Hence the missing statement in the proof is ∠1 ≅ ∠4.
