Answer
0.109589 millimeters per day.
Explanation
10 mm = 1 cm
4 cm = 4 × 10
= 40 mm
365 days = 1 year
rate to millimeters per day = 40 mm in 365 days
= 40/365 mm/day
= 8/73 mm/day
or = 0.109589 mm/day.
Rate to millimeters per day = 0.109589 millimeters per day.
Answer: [tex]\frac{8}{73} \text{ mm per day}[/tex]
Step-by-step explanation:
Since, the particular beach is eroding at a rate of 4 centimeters per year.
[tex]1 \text{ year } = 4 \text{ cm }[/tex]
⇒ [tex]365 \text{ days} = 4 \text{ cm }[/tex] [tex]( 1 year = 365 days )[/tex]
⇒ [tex]365 \text{ days} = 40 \text{ mm }[/tex] [tex]( 1 cm = 10 mm )[/tex]
⇒ [tex]1 \text{ days} = \frac{40}{365} \text{ mm }[/tex]
⇒ [tex]1 \text{ days} = \frac{8}{73} \text{ mm }[/tex]
⇒ [tex]\text{ The rate is } \frac{8}{73} \text{ mm per day}[/tex]
Which is the required expression.
