7.04, 7.134 ,7.2, 7.413
Step-by-step explanation:
Put all the white balls in one box and the red ball in the other so you have a 50% chance of winning if you put 1 red ball and a white now you have a 25% chance cause you have a 50% chance in choosing the right box then you have to chose the right ball which would be 50%
Answer:
It is when it has factors and can be multiplied
8x = 5(x+21)
8x = 5x +105
3x = 105
x = 105 /3
x = 35
8 x 35 = 280 miles away
The number of fish decreases by x% each year. x% can also be written as 0.01x.
If the total number of fish in a lake is A, after one year the number of fish will be:

After two years the number of fish will be:

So, the general formula for the number of fish after n years can be written as:

It is given that after 8 years, the number of fish is reduced to half. So we can write:
This means the value of x is 8.3%. So, the number of fish in a lake decreases by 8.3% each year
