Given the speeds of each runner below, determine who runs the fastest? emily runs 15 feet per second. jake runs 109 feet in 8 second. stephanie runs 1 mile in 467 second. tony runs 760 feet in 1 minute

The answer would be the first one. 15 times 8 is 120, and 15 times 60 is 900 so it is one.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
