Speedie ran the 200 meter race in 25.5 seconds. How much of an hour did it take Speedie to run the race? 1.0 hour = 3600.0 seconds

Speedie ran the race in 0.708(3)% of an hour, the 3 in the parentheses means the 3 repeats forever

Step-by-step explanation:

We have 25.5/3600, and when we convert it to a decimal, we have 0.00708(3), the 3 in the parentheses means the 3 repeats forever. To convert it to percentage, we multiply it by 100, to get 0.708(3). Hope it helps!

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
