Area of the base of the model
3*2 = 6 square feet
Since the actual building 120 times bigger than the model, it should be multiplied with 120
6*120 = 720 square feet
Slope is the change in Y over the change in. X
Using two of the given points:
Slope = 70-45 / 25-10
Slope= 25/ 15
Slope = 5/3
1. Average Speed is distance divided by time. So 363 divided by 165 is 2.2
2. For number 2 I am not sure if there is a missing piece to your question but the car has travelled 72 miles in 220 minutes
Basically looking for the x value of intersection of the two equations. Setting them equal,
2^x + 12 = 15x + 35, which you will get x = 7. Graph it out to get a visual solution.
The number of birds after 7 years would be 140, for both species.
so 15% off is 149.85 which makes it 849.85 then you add sales tax which is 79.92 and your cost is 929.07
