The half-life of carbon-14 is 5730 years. suppose a fossil is found with 27% of
carbon-14 as compared to a living sample. how old is the fossil?
(will give brainliest if you show work)

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

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.

ok thats very interesting
