3. two ocean beaches are being affected by erosion. the table shows the width, in feet, of each beach at high tide measured where 1995 is represented by year 0.
year number western beach width (in feet) dunes beach width (in feet)
0 100 25
5 90 45
10 80 70
11 78 75
12 76 80
15 70 95
a. between which years will the beaches have approximately the same width?
b. assuming these rates remain constant, what can do you get a better approximation of when the two beaches will have the same width?
just answer a and b that's it. : )

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =

step-by-step explanation:

step-by-step :

about 0.75 hours

step-by-step explanation:

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
