D
Step-by-step explanation:
Given that the starting population is 150 wolves, let the time when there will 25 wolves left be x, then
The increase in the number of wolves due to births is given by 150(1 + 0.15)^t = 150(1.15)^t
The decrease in the number of wolves due to dirths is given by 150(1 - 0.37)^t = 150(0.63)^t.
The number of wolves at time t is given by 150(1.15)^t - 150(0.63)^t = 150((1.15)^t - (0.63)^t).
Therefore, the function that could be used to predict when there will be 25 wolves in this group is 150((1.15)^t - (0.63)^t) = 25. (option D).

During a chess match there are 15 pieces left on the board. the ratio of the white pieces to black pieces is 3 : 2 how many white pieces are on the white board?
Answers
==========================================================
Explanation:
The ratio 3:2 scales up to 3x:2x for some positive whole number x.
We have 3x white pieces, 2x black pieces, and 3x+2x = 5x pieces total. Set this equal to the 15 mentioned and solve for x.
5x = 15
5x/5 = 15/5
x = 3
Therefore, there are 3x = 3*3 = 9 white pieces and 2x = 2*3 = 6 black pieces, which gives 9+6 = 15 total. The ratio 9:6 reduces to 3:2 after dividing both parts by the GCF 3.

The inequality that describes the given problem is x - 1.25 < 3.
The given parameters:
Number of paints used on the chair, = 1.25 LitersNumber of paints left for the table, less than 3 litersLet the number of liters in one can of yellow paint = x
The following inequality can be used to represent the liters of paint left for the table.
the liters of paint left = x - 1.25
The liters of paint left is less than 3 liters;
x - 1.25 < 3
Thus, the inequality that describes the given problem is x - 1.25 < 3.
