Answer:
D) 14.25
Step-by-step explanation:
It's basically saying when you use the ruler to measure something it will measure in 0.25. And will continue on to 0.50, 0.75, 1.00, 1.25, etc..
 
        
             
        
        
        
Answer:
22 feet
Step-by-step explanation:
Change 15 feet into inches using the conversion
1 foot = 12 inches, thus
15 ft = 15 × 12 = 180 inches
scale factor = 180 ÷ 3.75 = 48
Thus the actual dimensions of the boat are 48 times the model.
actual length = 48 × 5.5 = 264 inches = 264 ÷ 12 = 22 feet

Answer:
The problem with this question is that it is missing an important number, which is the length of the tube. Assuming that the tube is 10 meters long (=1,000 centimeters long)
time (in        distance traveled         distance traveled       distance
seconds)     by particle A in cms     by particle B in cms    between both
                                                                                               particles in cms
1                               97                            49                     854
2                               93                            47                     714
3                               89                            45                     580
4                               85                            43                     452
5                               81                            41                     330
6                               77                            39                     214
7                               73                            37                     104
8                               69                            35                     0
    
After 8 seconds both particles should meet. Particle A traveled 664 centimeters and particle B traveled 336 centimeters.
