Answer: 113 inches
Step-by-step explanation:
To solve the question, we have to find the perimeter of a circle since the skirt is circular. This will be:
Perimeter = 2πr
where
π = 3.142
r = diameter/2 = 36/2 = 18
The closest measurement needed for the sequin trim will then be:
= 2πr
= 2 × 3.142 × 18
= 113.112
= 113 inches
Answer:
option D. (-3,21),(-2,16),(0,6),(1,1),(2,-4)
Step-by-step explanation:
we have
we know that
To find the values of y substitute each value of x in the equation
so
1) For 
2) For 
3) For 
4) For 
5) For 
5x=25 could be one.
25/x-3=2 is another.
And the last one could be x/85+7=24
