so i need to find e missing side of each right triangle, side c is the hypotenuse!! a = 6.5m, b= 9m i have to round the answers to the nearest tenth if necessary

11.10 or 11.1 :)

Step-by-step explanation:

a² + b² = c²

6.5² + 9² = c²

42.25 + 81 = c²

42.25 + 81 = 123.25

123.25 = c²

√123.25 = c

√123.25 = 11.10 rounded :)

c= 11.10, if rounding to one decimal place, then 11.1 :)

answer: 414,377,008

step-by-step explanation:

just multiply it

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
