Use dimensional analysis to convert the quantity to the indicated units 27in to yd

There is 12 inches in 1 foot.

There is 3 feet in 1 yard.

12 inches divided by 1 foot = 27 inches divided by x feet.

12/1 = 27/x

12 = 27/x

12x = 27

x = 27/12

x = 2.25 feet

3 feet divided by 1 yard = 2.25 feet divided by x yards.

3/1 = 2.25/x

3 = 2.25/x

3x = 2.25

x = 2.25/3

x = 0.75

The answer is already rounded to the nearest hundredth so the answer is:

0.75 yd

14

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
