The equation d = 50 - 45h gives the distance d in miles that a bus is from the station h hours after leaving an arena. How far is the station from the arena? A 2,250 miles
B 50 miles
45 hiles
0.9 miles

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:

13.46

step-by-step explanation:

16.80 x .20 = 13.46

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours

i think the answer is c sorry if it's wrong
