When the burner is off there is no energy being produced.
Once you turn the burner in it begins creating energy which is used to cook.
The answer is: newly created energy that was not present earlier.

Answer: y = 12/(x^2)</h3>
============================================================
Explanation:
"y varies inversely as x^2" means y = k/(x^2) for some constant k.
Plug in (x,y) = (2,3) and solve for k
y = k/(x^2)
3 = k/(2^2)
3 = k/4
3*4 = k
12 = k
k = 12
The original equation updates to y = 12/(x^2)
As a check, plugging in x = 2 should lead to y = 3
y = 12/(x^2)
y = 12/(2^2)
y = 12/4
y = 3 ... we get the proper y value, so the answer is confirmed.
Answer:
Theo worked on it for 12 hours. Kade worked on it for 15 hours.
Step-by-step explanation: 12 plus 15 equals 27.
We are required to find the percent of an acres is this lot
The percent of acres of the lot is 27.55%
Area of an acre = 4840 square yards
Area of the lot = Length × width
= 40 feet × 100 feet
= 4000 square feet
<em>convert feet to yards</em>
1 foot = 0.333333
4000 square feet = 1333.333 square yards
Therefore,
Area of the lot = 1333.333 square yards
percent of an acres is this lot = 1333.333 / 4840 × 100
= 0.2754820247933 × 100
= 27.548202479338
Approximately,
27.55%
Therefore,
The percent of acres of the lot is 27.55%

Answer:
3.5
Step-by-step explanation:
To find the constant of proportionality between y/x you investigate the trend in values of x with corresponding values of y
For this case, when x =1, y=3.5
when x=2, y=7
Taking in case 1, y/x = 3.5/1 = 3.5
In case 2, y/x= 7/2 = 3.5
But you know that the constant of proportionality k is given by;
y=kx------------------------making k subject of formula
y/x=k
Hence in this case, your constant of proportionality is 3.5
