Answer:
Step-by-step explanation:
According to the given data:
A particular beach is eroding at a rate of 4 centimeters per year. A realtor converts this rate to millimeters per day
10 mm = 1 cm
Now convert 4 cm into mm
4 cm= 4*10 mm
4 cm= 40 mm
There are 3365 days in 1 year
Rate to millimeters per day = 40 mm in 365 days
= 40/365 mm per day
= 8/73 mm per day
Divide the term.. We get,
= 0.109589 mm per day .
AC = 8.9
BC = 6.5
(90% angle)
8.9 x 6.5 = <span>57.85
57.85/2 = 28.925
Area of ^ABC = 28.925 cm squared
DE = 55.1
55.1/ 11.02 = 5
DEF is 5 times as big as ABC
DF = 44.5
FE = 32.5
44.5 x 32.5 = 1446.25
1446.25/2 = 723.125
I am not positive but I believe DEF = 723.125 cm squared
Good Luck on the Test!! :D
