Arectangular eraser is 9 centimeters long. the area of the eraser is 45 square centimeters. the perimeter of the eraser is " blank" centimeters.

a. 18

b. 28

c. 14

B

Step-by-step explanation:

If one side is 9 and the area is 45, the other side must be 5 (45 divided by 9). You then add up the length of each side (5+5+9+9=28)

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

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
