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:
Answer:
The symphonic choir can record a maximum of 14 songs.
Step-by-step explanation:
We know that the album cannot be more than 72 minutes long, and the jazz choir records a total of song minutes.
If we call the number of songs the symphonic choir records , and each song is 3.5 minute long, then the song minutes for the symphonic choir are
; therefore, we have the inequality
<em> (this says the song minutes for jazz choir plus song minutes for symphonic choice cannot exceed 72 minutes )</em>
We solve this inequality by subtracting 21 from both sides and then dividing by 3.5:
The maximum integer value can take is 14; therefore, the maximum number of songs the symphonic choir can record is 14 songs.
