Question

In the past twenty years, scientists have seen the sea level rise at a rate of approximately 0.13 inches per year. If this rate continues, which best represents the change in sea level over the next 27 months (2.25 years)?

Answer 1

Given : scientists have seen the sea level rise at a rate of approximately 0.13 inches per year

To Find : which best represents the change in sea level over the next 27 months (2.25 years)

a. –2.925 inches

b. –0.2925 inches

c. 0.2925 inches

d. 2.925 inches

Solution:

Scientists have seen the sea level rise at a rate of approximately 0.13 inches per year

=> Water level increase  in a Year  = 0.13 inch

1 Year  = 12 months

=> Water level increase  in 12 months  = 0.13 inch

=> Water level increase  in 1 months  = 0.13/12 inch

=> Water level increase  in 27 months  =27 x  0.13/12 inch

= 9 x 0.13/4

= 1.17 / 4

= 0.2925

change in sea level over the next 27 months = 0.2925 inches

option c is correct

Scientists have seen the sea level rise at

a rate of approximately O.13 inches per

year

=>Water level increase in a Year = 0.13

inch

1 Year = 12 months

Water level increase in 12 months

0.13 inch

=>Water level increase in 1 months

0.13/12 inch

=>Water level increase in 27 months

=27 x 0.13/12 inch

=9x 0.13/4

=1.17/ 4

$\bold{\red{=0.2925}}$

change in sea level over the next 27

months =$\bold{\red{ 0.2925 inches}}$
