Rational numbers are numbers which can be written as a fraction (the formula is p/q). They don't include roots we can't solve in order to get a whole number and pi.
A. 776, pi, 25.209, √9 ---> NO (because of pi)
B. 726, 7/34, 20.209, √9 ---> YES
C. √3, 7/39, 20.3, √9 ---> NO (because of √3)
D. 726, 7/34, 20.209, √5 ---> NO (because of √5
Note that √9 = 3, so it IS a rational number.
Notice the picture below
now, we know their perimeter are the same for both
thus 4(a+4) = 6a
solve for "a"
10 x 15=150
150 is the answer
Answer:
meters
Step-by-step explanation:
From the answer choices, we basically need to find which of them is between
and 
<em>Converting all of them to decimals would make it really easier:</em>
<em />
<em>So we need to find number between -0.5 and -1.67</em>
<em />
<em>Answer choice A is -2.33</em>
<em>Answer choice B is -0.75</em>
<em>Answer choice C is -0.25</em>
<em>Answer chioce D is -1.83</em>
<em />
<em>So which number, from the choices, is between -0.5 & -1.67?</em>
Clearly, it is -0.75, or,
meters
