Correct answer is A) StartFraction 4 centimeters Over 1 year EndFraction times StartFraction 10 millimeters Over 1 centimeter EndFraction times StartFraction 1 year Over 365 days EndFraction
Step-by-step explanation:
We have , A particular beach is eroding at a rate of 4 centimetres per year. A realtor converts this rate to millimetres per day. We need to find correct expression, when evaluated, results in the correct units and numerical value . Let's find out:
We know that, A particular beach is eroding at a rate of [tex]4\frac{cm}{year}[/tex]
[tex]1cm = 10mm[/tex]
[tex]1 year = 365 days[/tex]
⇒ [tex]4(\frac{cm}{year})[/tex]
⇒ [tex]4(\frac{10mm}{year})[/tex]
⇒ [tex]4(\frac{10mm}{365days})[/tex]
⇒ [tex]\frac{40mm}{365days}[/tex]
⇒ [tex]\frac{8mm}{73days}[/tex]
Therefore, According to calculations, Correct answer is A) StartFraction 4 centimeters Over 1 year EndFraction times StartFraction 10 millimeters Over 1 centimeter EndFraction times StartFraction 1 year Over 365 days EndFraction
