The question that is asked is pretty straight forward. Only thing that needs to be found is the number of 30 in the number 600. By dividing 600 by 30 we can arrive at the desired result. 
Number of 30 in 600 = 600/30
                                 = 60/3
                                 = 20
So there are 20 number of 30s in the number 600. This method can be used to find answers to several other similar kind of questions like the number of 10s in 1000.Following the same procedure we get
Number of 10 in 1000 = 1000/10
                                   = 100
        
                    
             
        
        
        
Answer:
 70 seconds
Step-by-step explanation:
Given that;
The initial velocity  of the bullet fired = 1120 ft/s
 of the bullet fired = 1120 ft/s
Initial height h = 8 feet
The expression to determine how many seconds it takes the bullet to hit the ground is:

Thus;
Replacing the value of  =  1120 and h = 0 (i.e. when h =0) in the above expression; we have:
 =  1120 and h = 0 (i.e. when h =0) in the above expression; we have:


= -16t² + 1120t + 8
mulitiply through by (-)
= 16t² -1120t - 8
Divide through by 8
= 2t² -  140t - 1
The above expression forms a quadratic equation.
where;
a = 2
b = -140
c = - 1
So, by using the quadratic formula  , we have:
, we have:






= 70 
Thus, the time (in seconds) it took the bullet to it the ground = 70 seconds

Answer:
Test A: 40 words per minute
Test B: 54 words per minute
Test C: 44 words per minute
<em><u>Test B has the highest unit rate</u></em>
Step-by-step explanation:
Test A divide 30 by  (30/0.75=40)
 (30/0.75=40)
Test B divide 78 by  (78/1.5=52)
 (78/1.5=52) 
Test C divide 99 by  (99/2.25=44)
 (99/2.25=44)
<u>Hope this helps :-)</u>
