X is 70 degrees
Step-by-step explanation:
In a triangle, all the angles add up to 180. 
We can set up an equation: 
48+62+x=180
x=180-(48+62)
x=70
 
        
             
        
        
        
Answer: B. a savings account earns interest

Answer:
$0.95
Step-by-step explanation:
Given that weight of the function = x
Given that cost of the postage for mail having weight less than or equal to 1 oz = $0.44
then to find the equation can be written as 
C(x)=0.44  where 0<x<=1
Similarly we can write equation for other parts
C(x)=0.61  where 1<x<=2
C(x)=0.78  where 2<x<=3
C(x)=0.95  where 3<x<=3.5
Now we can write them together as piecewise function as shown in below:

to graph that we just draw horizontal lines for each as none equation contains x on the right side .
3.48 oz is less that 3.5 so we will use $0.95.
