Answer:
The correct answer is 24 
Step-by-step explanation:
to solve this you will need to use the pathagreom theorum 
a^{2}+b^{2}=c^{2}
A= one side lenth
B= the secons side lenth 
C= hypotnuse 
It is helpfull to draw out the situation 
you know that the latter is 25 ft, that is your hypotnuse 
you also know that the 7 ft away from the base of the building is one of the side lenths, lets call it side a 
so plug the numbers into the equation 
7^2 + b^2 = 25 ^2 
you leave b^2 alone because that is the side you are trying to find 
now square 7 and 25 but leave b^2 alone 
49 + b^2 = 625 
now subtract 49 from both sides 
b^2 = 576 
now to get rid of the square of b you have to do the opposite and square root both sides removing the square of the B and giving you the answer of..........
B= 24 
Hope this helped!! I tryed to explain it as simpil as possiable 
 
        
                    
             
        
        
        
The conclusion is valid
it is a systematic random sample
and the second one is a line graph (I think)
        
                    
             
        
        
        
So,
53,879 rounded to the nearest hundred:
If the number in the tens place is greater than or equal to 5, then round up.  If not, round down.
7 is greater than or equal to 5, so round up.
53,879 --> 53,900
        
                    
             
        
        
        
Answer:
Use the explantion to answer your question
Step-by-step explanation:
Amount he paid for first 20 shares
= $25 + (20 x $10.51)
= $25 + $210.20
= $235.20
Amount he paid for next 20 shares
= $25 + (20 x $8.93)
= $25 + $178.60
= $203.60
Thus, total amount paid
= $235.20 + $203.60
= $438.80
