You don’t need to do the math, think logically.
35% is almost 33%.
1/3 (33%) of 64,000 is 21,000.
The closest choice is H. 22,400.
The perimeter of a triangle is the sum of all side lengths of the triangle. The numerical expression for the perimeter of Stephanie's triangle is: ![\frac 12 \times 25](https://tex.z-dn.net/?f=%5Cfrac%2012%20%5Ctimes%2025)
Let the sides of Juan's triangle be x, y and z. So:
![x = 5 \\ y = 8\\ z = 12](https://tex.z-dn.net/?f=x%20%3D%205%20%5C%5C%20y%20%3D%208%5C%5C%20z%20%3D%2012)
The perimeter (J) of Juan's triangle is calculated by adding all sides.
So:
![J =x +y +z](https://tex.z-dn.net/?f=J%20%3Dx%20%2By%20%2Bz)
This gives:
![J =5 + 8 + 12](https://tex.z-dn.net/?f=J%20%3D5%20%2B%208%20%2B%2012)
![J =25](https://tex.z-dn.net/?f=J%20%3D25)
From the question, we understand that:
The perimeter (S) of Stephanie's triangle is half that of Juan.
This means that:
![S = \frac 12J](https://tex.z-dn.net/?f=S%20%3D%20%5Cfrac%2012J)
Substitute 25 for J
![S = \frac 12 \times 25](https://tex.z-dn.net/?f=S%20%3D%20%5Cfrac%2012%20%5Ctimes%2025)
Hence, the numerical expression for the perimeter of Stephanie's triangle is: ![\frac 12 \times 25](https://tex.z-dn.net/?f=%5Cfrac%2012%20%5Ctimes%2025)

Answer:
A. {−3.5, −2, 1, 2.5}
Step-by-step explanation:
Remember that the range is the possible values for Y in any given function, so in this case, we are given the Y values and we have to solve the function for x:
y=9+6x
6x=y-9
So we just insert the values, the first one being -12.
So since from the options only A has -3.5 as an option that's the correct answer.

Answer:
![A=45000(0.82)^t](https://tex.z-dn.net/?f=A%3D45000%280.82%29%5Et)
Step-by-step explanation:
Given data
P= 45,000
rate= 18%
Recall the expression for the compound interest
![A=P(1+r)^t](https://tex.z-dn.net/?f=A%3DP%281%2Br%29%5Et)
Since we are talking of depreciation
![A=P(1-r)^t](https://tex.z-dn.net/?f=A%3DP%281-r%29%5Et)
Substitute
![A=45000(1-0.18)^t\\\\A=45000(0.82)^t](https://tex.z-dn.net/?f=A%3D45000%281-0.18%29%5Et%5C%5C%5C%5CA%3D45000%280.82%29%5Et)
Hence the exponential function is
![A=45000(0.82)^t](https://tex.z-dn.net/?f=A%3D45000%280.82%29%5Et)
