Answer:
➩ 2,250 envelopes.
Step-by-step explanation:
Given that, Nicole buys 125 envelopes per box for her home office.
Therefore, She will have 18*125 envelopes in all
So, 18*125 is 2,250 envelopes 
 
        
             
        
        
        
144/200=0.72 or 72%
225/100=2.25 or 225%
42/50=0.84 or 84%

Answer:
20°
Step-by-step explanation:
One way of doing this is to find the constant of proportionality, k:
8k + 6k + 4k = 90°    Then 18k = 90°, and k turns out to be 90/18, or 5.
Then the angles are 8(5), 6(5) and 4(5).  The smallest of these angles is thus 20°
