Step-by-step explanation:
Change  to a percent, that is
 to a percent, that is
 × 100% = 0.28 × 100% = 28%
 × 100% = 0.28 × 100% = 28%
Then 34% + 28% = 62% ← go by bus or car, leaving
100% - 62% = 38% walking to school
 
        
             
        
        
        
Answer:
1. Marcia
2. (I do not understand what this question is asking)
3. Marcia's estimation is closer
4. 690 people per year
Step-by-step explanation:
1. Marcia's estimation has a greater number of people because he estimated 600 people per year, while Adam estimated 2% of 12,500 (250 people per year).
2. (I do not understand what this question is asking)
3. marcias guess was 600 (600x50+12,500 = 42,500. 42,500 - 35,400 = 7,100) while Adam's guess was 250 per year (250x50+12,500 = 10,400). Therefore, Marcia's guess was closer to 35,400.
4. If Marcia adjusted her answer so that the population in Burbville was ACTUALLY going to be 34,500, she would need to adjust her estimation to 690 people per year.
Hope this helps! So sorry I couldn't understand question 2!
 
        
             
        
        
        
Answer:
15.8
Step-by-step explanation:
First we need to round to the nearest tenth. 
18.134 rounds to 18.1 (since it's closer to 18.1 than 18.2)
2.28 rounds to 2.3 (since it's closer to 2.3 than 2.2)
Then we subtract
 18.1-2.3=15.8
 
        
                    
             
        
        
        
The answer is false 
if you solve both sides it says that 627.25 is less than 3.714 which isn't correct because 627.25 is obviously greater than 3.714
