A 12-inch candle is lit and steadily burns until it is burned out. As the burned length of the candle increases from 4 to 7.5 in
1 answer:
Answer:
The remaining length of the candle varies from 8 inches to 4.5 inches.
The required expression is:
Where, b represents the burned length and r represents the remaining length.
Step-by-step explanation:
Consider the provided information.
A 12-inch candle is lit and steadily burns until it is burned out.
The length of the candle is 12 in.
The burned length of the candle is 4 in.
That means the remaining length is 12 - 4 = 8 in
The burned length of the candle is 7.5 in.
That means the remaining length is 12 - 7.5 = 4.5 in
Hence, the remaining length of the candle varies from 8 inches to 4.5 inches.
Suppose b represents the burned length of the candle in inches (or the number of inches that have burned from the candle since it was lit) and r represents the the remaining length of the candle (in inches).
The required expression is:

<h2>Answer:</h2>
This is a square pyramid because it's a solid having a square base. The point up the pyramid is called the apex and is directly above the middle of the square base. The surface area of a solid is the total area of its outer surface. If we unfold this pyramid, we'll get one square and four identical triangles. So the surface are can be calculated as follows:
FOR THE SQUARE:
FOR THE TRIANGLE:
