The school department made $2,142 on ticket sales for 3 nights. each ticket costs $7. how many tickets did they sell each night?

25 7/8inches

Step-by-step explanation:

The length of the rod is equal to the side length of the equilateral triangle

Let the length of the rod be x

Since an equilateral triangle has all its sides equal, its perimeter is expressed as;

P = x+x+x

P = 3x

Given x =8 5/8

P = 3(69/8)

P = 207/8

Express as mixed fraction

P = 25 7/8 inches

Hence the length of the rod used to create the bell is 25 7/8inches
