Acertain forest covers an area of 3900 km2 . suppose that each year this area decreases by 7.75% . what will the area be after 15 years?

1162.94 km²

Step-by-step explanation:

forest cover area = 3900 km²

Area decreases every year by = 7.75 %

area after 15 years(A) = ?

so, the area of forest remaining after 15 years as it decreases by 7.75 % every year is equal to  1162.94 km²

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

13664

step-by-step explanation:

=cross multiply

=100 x = 13664
