Answer:

56th second

Step-by-step explanation:

Given

Lola = Every\ 8\ seconds

Keegan = Every\ 14\ seconds

Time = 2\ minutes\ 10\ seconds

Required

Determine when they sing together

First, we convert the total time to seconds.

Time = 2\ minutes\ 10\ seconds

Time = 2 * 60\ seconds +  10\ seconds

Time = 120\ seconds +  10\ seconds

Time = 130\ seconds

Next, we determine the Least Common Multiple of Lola and Keegan's time:

Lola:

8\ seconds = 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, 128

Keegan:

14\ seconds = 14, 28, 42, 56, 70, 84, 98, 112, 126

<em>The least common multiple is 56. Hence, they will sing together at the 56th second</em>

From the beginning of cross country season to the end , Trisha reduced her time by 17 % , Anchara reduced hers by 4/25 , and Jua
kati45 [8]
Trisha - 17 percent
Anchara - 4/25 = 0.16 = 16 percent
Juanita - 16 - 13.3 = 2.7   2.7/16 (since 16 is the total) = 0.16875 = 16.875 percent

So Trisha reduced her time by the greatest percent (17)
