Answer:
yvaires directly as x means
y=kx
y varies inversly with z means
y=k/z
therfor
y=(kx^2)/z
k=constant of variation
6=(k9^2)/27
6=(k81)/27
6=3k
divide both sides by 3
2=k
the constant of variation is 2

Answer:
There are 5040 different anagrams of FLORIDA.
Step-by-step explanation:
We are given the following in the question:
Anagram of FLORIDA.
Letters are:
F, L, O, R, I, D, and A
There are 7 letters.
Thus, the number of anagrams are given by n!, where n are the number of letters in the word.
Number of anagrams =
Thus, there are 5040 different anagrams of FLORIDA.
Explanation:
If your actual answer is very far from your estimate, you probably made a mistake somewhere.

<em>Additional comment</em>
50 years ago, when a slide rule was the only available calculation tool, making an estimate of the result was a required part of doing the calculation. Not only were the first one or two significant digits needed, but also the power of 10 that multiplied them. Use of a slide rule required the order of magnitude be computed separately (by hand) from the significant digits of the result.

You may also find it useful to estimate the error in your estimate. That is, you may want to know the approximate answer to 2 (or more) significant digits in order to gain confidence that your calculation is correct.
The complete factor of the expression 
is 
correct option is D.
<h3>What is a factorization?</h3>
It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The expression is .
To solve the expression properly we have to take common (2x²). Then we have
The factor is .

Answer:
3/40
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 9 and 120 is 3
Divide both the numerator and denominator by the GCD
9 ÷ 3
120 ÷ 3
Reduced fraction:
3/40
