Assume that the rule connecting height of the candle to time is a linear one. If you do, then we have to find the equation of this line, and then use this equation to predict the height of the candle after 11 hours.
Two points on this line are (6,17.4) and (23, 7.2). The slope is thus
7.2-17.4 -6
m = --------------- = ----------- or -3/5.
23-6 10
Find the equation of the line. I'm going to use the slope-intercept formula:
y = mx + b => 7.2 = (-3/5)(23) + b. Solving for b, b = 21.
Now we know that y = (-3/5)x + 21
Let x=11 to predict the height of the candle at that time.
y = (-3/5)(11) + 21 = 14.4 inches (answer)
Move the decimal five places until it is after one number, and because the number got bigger, your exponent is a negative.

Answer:
40,000
Step-by-step explanation:
You just add 60,000 and 30,000 which makes 90,000 and subtract it with the 50,000 then which equals to 40,000. <em>you don't need to rate me.</em>
