Answer:
58 inches
Step-by-step explanation:
15+12=27+14=41+9=50+8=58
For every 6000 square feet in a building, there is one fire extinguisher.
So for 135000 square feet, the equation is like direct proportion (because the more the square feet, the more fire extinguishers needed).
1 : 6000
x : 135000
Multiply x with 6000, and 1 with 135000.
So, the result is:
6000x = 135000
x = 135000/6000
x = 22.5
Well, there are a few ways to go about this problem. The easiest would be to compare the rates.
Nola did -200 feet in 10 min so we have -200 / 10
Next, Nola did -300 in 20 mins so we have -300/10
Now that we have our slope/rate we can compare the two.
-200 / 10 = -20 ft/min
-300 / 20 = -15 ft/min
As we can see, Nola walked down during the first portion at a faster rate, which she went down -20 ft/min
The answer I got is r= -3.5
