Answer:
20 soap things.
Step-by-step explain: 5X1/4= 20
Answer: hey sup fellow player
Step-by-step explanation: how’s life eh?
From any proportion, we get another proportion by inverting the extremes (or the means):
= k
so we have:
2x=3k
2x+y=2k therefore:
3k+y=2k
y= - k
x=
= -
The corect answer is A. -3/2
or:
From any proportion, we get another proportion by inverting the extremes and the means:
We use a property of proportions:
where a, d are extremes and b,c are means and the product of the extremes equals the product of the means (a*d=b*c),
so we have
or
(you can check this also by "the product of the extremes equals the product of the means")
3y = - 2x
Error=100 calculated/actual
error=100 (175-97.5) / 97.5
error=100 (77.5) / 97.5
error=7750 / 97.5
error=77500 / 975
error=3100 / 39
error=79.5% <-- Estimated
Answer:
The binomial theorem allows you to write out the expansion of your polynomial immediately. (I feel like this is good enough)
Step-by-step explanation:
<em>It also allows you to answer such questions as:</em> "What is the coefficient of x20 in (1+x)100?" Its generalization to non-integer exponents allows you to get the expansion of (1−x)−1/2. There are all sorts of reasons.
