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)
Answer:
29.2 percent decrease
Step-by-step explanation:
the difference between 96 and 68 is 28 bucks
28 is what percent of 96
is over of
x/100 x 28/96
cross multiply=2800/96
divide 2800 by 96 and the answer is 29.1666
Explanation:
Datum: Area, <span>A=18<span>13</span>f<span>t2</span></span> and height, <span>h=31ft</span>
Required: Base of the parallelogram?
*Solution: Area, <span>A=b×h</span>
<span>18<span>13</span>f<span>t2</span>=b×31ft</span> solve for base, b
<span>b=<span>553</span>×<span>131</span>=<span>5593</span>=.591f<span>t</span></span>
