1/2 a pound per dog
3 1/2=3.5lbs
3.5÷7=.5
.5=1/2
        
             
        
        
        
Answer: 0.22hz
Step-by-step explanation:
Hi to answer this question we have to analyze the information given:
- <em>Period (T) = 4.5 Seconds
</em>
So, to calculate the frequency of the pendulum we have to apply the formula;
Frequency (f)= 1 / period  
Replacing with the value given:
f = 1/ 4.5 sec = 0.22 hz

False, 24 x 10 x 90 = 21,600, 90 x 2,400 = 216,000
        
                    
             
        
        
        
(4/5)-(3/8)=17/40 or 0.425 mile
        
             
        
        
        
You would plug in twenty eight point nine to the q. So it would be five point one plus twenty eight point nine divided by three point four, which equals thirteen point six.
