In this question, we have to write the set of points from -6 to 3 but excluding -2 and 3 as a union of intervals .
For union, we use U.
For the points that we have to exclude , we put parenthesis on there side  that is  ().
Therefore the required interval form is

As we see that () are used with -2 and 3 . And that's the required interval form .
 
        
             
        
        
        
Answer:
Speed of turtle = 11.25 miles/hour
Step-by-step explanation:
1 7/8 miles / 1/6 hour
= 15/8 / 1/6
= 15/8 * 6 
= 11.25 miles/hour
 
        
                    
             
        
        
        
Answer:
B
Step-by-step explanation:
the measure of the chord- chord angle ABC is half the sum of the arcs intercepted by the angle and its vertical angle , that is
∠ ABC =  (AC + DE) =
 (AC + DE) =  (75 + 45)° =
 (75 + 45)° =  × 120° = 60°
 × 120° = 60°
 
        
             
        
        
        
Because the angles are supplementary, they add to 180 degrees.
I solved this by dividing 

 which gives me 30 degrees.
multiply 30 by 5 gives you 150.
and 30 + 150 = 180 
 
        
        
        
You see how many times 4 can go into 25 witch is 6 not 7 because 7 x 4 is28 and 28is bigger than25 so the answer is and 1/4 is25 cence so the answer is 4.25
