The common denominator of the given expression is 5y+6.

Given expression,

\dfrac{y+\frac{y-3}{3} }{\frac{5}{9} +\frac{2}{3y} }.

We have to find the common denominator.

On solving the numerator and denominator of the  given expression,

\dfrac{y+\frac{y-3}{3} }{\frac{5}{9} +\frac{2}{3y} }= \dfrac{\frac{3y+y-3}{3} }{\frac{5y+6}{9y} }

       = \dfrac{\frac{4y-3}{3} }{\frac{5y+6}{9y} }

= \dfrac{4y-3}{3} \times\dfrac{9y}{5y+6}

Or,\dfrac{y+\frac{y-3}{3} }{\frac{5}{9} +\frac{2}{3y} }= \dfrac{3y(4y-3)}{5y+6}

Hence the common denominator of the above expression is given by 5y+6.

What is the measure of an interior angle of a regular three-sided polygon?
noname [10]
The formula to find the measure of an interior angle is (n - 2) * 180/n, where n represents the number of sides in the polygon. In this problem, n would represent 3. 

Let's plug in the value for n
(3 - 2) * 180/3
Let's simplify that. 
=60

Now we know that the <span>measure of an interior angle of a regular three-sided polygon is 60</span>°. Your answer would be B!

Let me know if you have any questions regarding this problem!
Thanks!

What is the simplified form of the following expression?
kogti [31]

Answer:

\sqrt{3}


Step-by-step explanation:

We will be using 2 properties of radicals in this simplification (outlined below).

  • \sqrt{a*b}=\sqrt{a}* \sqrt{b}
  • \sqrt{a}*\sqrt{a}=a

<em>Let's simplify this:</em>

2\sqrt{27} +\sqrt{12} -3\sqrt{3}-2\sqrt{12}\\ =2\sqrt{9*3}+\sqrt{4*3} -3\sqrt{3}-2\sqrt{4*3} \\=2\sqrt{9} \sqrt{3} +\sqrt{4} \sqrt{3}-3\sqrt{3}-2\sqrt{4} \sqrt{3} \\=2(3)\sqrt{3}+(2)\sqrt{3} -3\sqrt{3}-2(2)\sqrt{3} \\ =6\sqrt{3} +2\sqrt{3}-3\sqrt{3}-4\sqrt{3}  \\=\sqrt{3}


First answer choice is right.

If 90 percent of a is 44, what is 30 percent of 3a?
Lesechka [4]
90% of "a" is 44.......turn ur percent into a decimal...." of " means multiply..." is " means equals...

0.90a = 44...divide both sides by 0.90
a = 44 / 0.90
a = 48.89.....this is rounded

what is 30% of 3a.....and we know that "a" is 48.89...

0.30(3 * 48.89) = 0.30(146.67) = 44 <=== ur answer
