Answer:
the length of the shadow is 45 feet long
Step-by-step explanation:
If y varies directly with x, means that they can be modeled by a linear equation, lets choose a line with 0 y intercept, that is:
y = mx + b
y = mx
where m is the slope of the line, now we plug in the data we have:
y = mx
20/3 = m(30)
solving for m:
m = (20/3)(1/30)
m = 20/90
m = 2/9
so the line equation, or function modeling the y and x relationship is:
y = (2/9)x
So... T = 1.25?, if this isn't correct ask the question again.. i don't fully get it
15 and 12 are means and 3 and 60 are extremes of the above proportion.
Explanation:
Means and Extremes of Proportion
Suppose two ratios a:b and c:d are in proportion.Then it can be expressed as
<span><span>ab</span>=<span>cd</span></span>
Here, a, d = extremes and,
b, c = means
