After 7 years the laptop computer will be worth $200 or less.
In this question, we have been given a laptop computer is purchased for $1500 . Each year, its value is 75% of its value the year before.
We need to find the number of years when laptop computer be worth $200 or less.
We can see that given situation represents exponential decay function with initial value 1500, decay rate = 0.75 and the final value = 200
We need to find period t.
For given situation we get an exponential function as,
1500 * (0.75)^t ≤ 200
(0.75)^t ≤ 2/15
t * ln(0.75) ≤ ln(2/15)
t * (-0.2877) ≤ -2.0149
t ≥ (-2.0149)/(-0.2877)
t ≥ 7
Therefore, the laptop computer will be worth $200 or less after 7 years.

The number of congruent triangles formed from dissecting the polygon using the center point and two adjacent vertices is equal to the number of sides of the polygon. Therefore, for the a polygon with five sides, five congruent triangles are formed and seven for the polygon with seven sides.
Hello There!
So we divide fractions by multiplying by the reciprocal.
So let’s change 6/7 divided by 3/8 to 6/7 multiplied by 8/3.
Once we do that, we can start our multiplication.
Once we multiply, we get 48/21
We can both divide these by 3 to simplify it so once we divide we will get
16/7
This can be turned in a mix number and it would be 2 and 2/7
