Answer:
16cats and 19 birds
Step-by-step explanation:
if we say that x is birds and y is cats we can say that:
4.5x+8.5y=221.5 ( the amount birds and cat both need)
y+x =35 (number of cats and cats)
x=35-y
4.5(35-y) +8.5y= 221.5
157.5-4.5y +8.5y =221.5
4y=64
y= 16
16+x=35
x=19

Answer:
a) The table of values represents the ordered pairs formed by the elements of the sequence ( ) (range) and their respective indexes (
) (range) and their respective indexes ( ) (domain):
) (domain):
  
         
 1         6
 2        11
 3        16
 4        21
 5        26
b) The algebraic expression for the general term of the sequence is  .
.
c) The 25th term in the sequence is 126.
Step-by-step explanation:
a) Make a table of values for the sequence 6, 11, 16, 21, 26, ...
The table of values represents the ordered pairs formed by the elements of the sequence ( ) (range) and their respective indexes (
) (range) and their respective indexes ( ) (domain):
) (domain):
  
         
 1         6
 2        11
 3        16
 4        21
 5        26
b) Based on the table of values, we notice a constant difference between two consecutive elements of the sequence, a characteristic of arithmetic series, whose form is:
 (1)
 (1)
Where:
 - First element of the sequence.
 - First element of the sequence.
 - Arithmetic difference.
 - Arithmetic difference.
 - Index.
 - Index.
If we know that  and
 and  , then the algebraic expression for the general term of the sequence is:
, then the algebraic expression for the general term of the sequence is:

c) If we know that  and
 and  , then the 25th term in the sequence is:
, then the 25th term in the sequence is:


The 25th term in the sequence is 126.
 
        
             
        
        
        
Answer:
V= area of cross-section x length 
V = 0.5x(8x9) x 11
V = 396cm^3
