If the game will start at 11:00 A.M., but the players must arrive at the field three-quarters of an hour early to warm up, it refers to 8:45 a.m. Why? If we start to count in 11 backward and start to trace the three-quarters, it shows that 10:45, 9:45, and 8:45 are the three-quarters. So Hamid statement that he has to be at the field at 9:45 A.M is not correct.
If TU is 7.5 and UC is 17.5, TV = 25 because you just add the two together
Factor ||5||−||−5||−(−5)|5|-|-5|-(-5) = 25 =5² ( 2 prime factors, 1 distinct)
Divisors = 1,3,25 (3 divesors)
