1+33+57=180
1+90=180
1= 90
Answer:
75%
Step-by-step explanation:
First we can solve the area of the rectangle originally the answer is:
4 × 2 = 8
Then we decrease both measurements by 50% to get the dimensions 1 and 2. The new area will be 1 × 2 which is 2.
2 is 25% of 8 which means that the area of the rectangle has been reduced by 75%.
Answer:
![20x^2-12x](https://tex.z-dn.net/?f=20x%5E2-12x)
Step-by-step explanation:
The area of a rectangle can be expressed as the length multiplied by the width. Plugging in the values given, you get

Answer:
Decrease of 63.5%.
Step-by-step explanation:
Exponential function:
An exponential function has the following format:
![y = y(0)(1+r)^{x}](https://tex.z-dn.net/?f=y%20%3D%20y%280%29%281%2Br%29%5E%7Bx%7D)
In which y(0) is the initial value and r is the rate of change, as a decimal. If r is positive, it is a increase. If it is negative, it is a decrease.
In this question:
We have that:
![y = 3100(0.365)^x](https://tex.z-dn.net/?f=y%20%3D%203100%280.365%29%5Ex)
So
![1 - r = 0.365](https://tex.z-dn.net/?f=1%20-%20r%20%3D%200.365)
![r = 0.365 - 1 = -0.635](https://tex.z-dn.net/?f=r%20%3D%200.365%20-%201%20%3D%20-0.635)
So a decrease of 63.5%.
