Question

a particular beach is eroding at a rate of 4 centimeters per year. a realtor converts this rate to millimeters per day. which expression, when evaluated, results in the correct units and numerical value?

Answer 1

4 cm / 1 year)*(1 year / 365 days)*(10 mm / 1cm) = 0.1096 mm/day
Hope this helps you !!

Answer 2

`(8)/(73)(mm)/(days)`

Explanation:

we know that

A particular beach is eroding at a rate of
`4(cm)/(year)`

Remember that

`1\ cm=10\ mm`

`1\ year=365\ days`

so

substitute

`4(cm)/(year)=4(10)/(365)=(40)/(365)(mm)/(days)`

simplify

`(40)/(365)(mm)/(days)=(8)/(73)(mm)/(days)`
