4 pack: 13/4=3.25
5 pack: 16/5=3.2
8 pack: 28/8= 3.5
the 5 pack is the cheapest per bulb so it has the best value
Answers:
- The equation is W = 33T + 500
- After 14 minutes, there are <u> 962 </u> liters of water.
=======================================================
Explanation:
- T = number of minutes
- 33T = amount of added water in liters, since we're adding 33 liters per min.
- 33T+500 = adding on the initial 500 liters
This leads to the equation W = 33T + 500
------------------------
Plug in T = 14
W = 33T + 500
W = 33*14 + 500
W = 462 + 500
W = 962 liters of water are in the pond after 14 minutes
Answer: 3
Step-by-step explanation:
Answer: 45000
Step-by-step explanation:
From the question, we are informed that Patty buys a new car and gets it appraised every few years and that after owning the car for 3 years, its value is $15,000 and further told that after owning the car for 5 years, its value is $9,000.
Let the number of years be x
Let the value of the car be y.
From the first part of the question, we are told that after owning the car for 3 years, its value is $15,000.
Since an inverse variation will be:
x = k/y
3 = k/15000
k = 15000 × 3
k = 45000
Let's confirm the value of k for the second part of the question. After owning the car for 5 years, its value is $9,000. Here, x=5 and y = 9000
x = k/y
x = 45000/9000
x = 5
It's correct.
Therefore, the constant of proportionality is 45000
