Answer:
Mean is 18
Step-by-step explanation:
We would set up the proportion as X/9=36/X so after we cross multiply we get x^2=324. Then we find the square root of both sides to simplify. ... And the square root of 324 is 18. So the final answer is x=18 or the geometric mean is 18
Answer:
1. $0.80 or 80 cents
2. 1.25 meters
Step-by-step explanation:
The equation p=0.8L represents the price p (in dollars) of a piece of nylon rope that is L meters long.
1. To find how much the nylon costs per meter, take L = 1 (this means you are calculating the price of a piece of nylon rope that is 1 meter long):

2. To find how long a piece of nylon rope that costs $1.00 is, substitute into the equation p = 1:

Parking lot A equation- $3.00 + $9.00x
Parking lot B equation- $10.00 + $6.00x
Part A- For 3 days parking lot B would be the better option- $28
Part B- For 8 days parking lot B would also be the better option- $58
