I think Victoria's method is linear because the number of minutes is increased by an equal factor every month. 35+15=50+15=65+15=80
Answer:
666.67 ft^2
Step-by-step explanation:
We start with a 4x5 scale room
We then use the 1:20 scale to multiply the 4 and the 5 by 20
4*20=80
5*20=100
We now have the dimensions of the actual room, 80in.x100in.
Area=length*width
A=100*80
A=8000 in^2
We are not done yet, though. To get feet, you convert inches to feet. 1 foot=12 inches.
8000/12=666.667, or 666.67, or 667, depending what you would round to
D. no solution
Because they never found each other, the point they cross on is the solution.
Consider rectangular box with
- length x units (x≥0);
- width 3 units;
- height (8-x) units (8-x≥0, then x≤8).
The volume of the rectangular box can be calculated as

In your case,

Note that maximal possible value of the height can be 8 units (when x=0 - minimal possible length) and the minimal possible height can be 0 units (when x=8 - maximal possible length).
From the attached graph you can see that the greatest x-intercept is x=8, then the height will be minimal and lenght will be maximal.
Then the volume will be V=0 (minimal).
Answer: correct choices are B (the maximum possible length), C (the minimum possible height)
