Answer:
The amount of wood left is 36 9/16 in 
Step-by-step explanation:
Here, we want to get the amount of wood left 
To calculate this, we have to subtract what is cut and what is wasted from the original total length 
So we have what is left as follows;
45 1/2 - 8 7/8 - 1/16
45 1/2 = 91/2
8 7/8 = 71/8
91/2 - 71/8 - 1/16
(728 - 142 - 1)/16
585/16 = 36 9/16 in

Answer:
<em>    The value of [g ◦ f](x) =  </em>
</em>
Step-by-step explanation:
     If f(x) = 2x - 1
     g(x)  = 
     we need to find the value of [g ◦ f](x).
     which means that g(f(x))
     g(f(x)) = 
     g(f(x)) = 
     g(f(x)) = 
<em>     The value of [g ◦ f](x) =  </em>
</em>
 
        
             
        
        
        
12• (0.25) • (-8) ÷ 1/3 • 5
3• (8) ÷ 1/3 • 5
24 • 1/3 • 5
8 • 5
40
Until the second step is ok.
in the third step, she multiplied the 1/3 term instead if dividing it
24 ÷ 1/3 . 5
24 ÷ 5/3
72/5
