Read the problem and examine the diagram.
yulyashka [42]

Answer:

Option A: The answer should be 10% of 6 is the correct answer.

Step-by-step explanation:

Given that:

6 students play trumpet. As they represent 10% of the total students.

Let,

x represent the number of students in the band.

10% of x = 6

By solving this, we will get the value for number of students in the band.

As x will be our answer,

The choices B, C and D are correct in the given scenario.

However,

10% of 6 cannot be the solution to the problem.

Hence,

Option A: The answer should be 10% of 6 is the correct answer.

36a^2+24b^2=12( +2b^2)
vlabodo [156]
The blank space is found by dividing 36a^2 by 12, which is equal to 3a^2
To get to this answer you need to
1. divide the both sides of the equation by 12.
2. subtract 2b^2 from both sides. 
You will see that the blank space equals 3a<span>^2 then</span>

10. simplify the rational expression by rationalizing the denominator.( 1 point ) 4√150/√189x
ddd [48]
Rationalizing the denominator, simply means "getting rid of that pesky root at the bottom", and we do so by simply multiplying it by something to take it out, of course, we multiply the bottom, we have to also multiply the top,

\bf \cfrac{4\sqrt{150}}{\sqrt{189x}}\cdot \cfrac{\sqrt{189x}}{\sqrt{189x}}\implies \cfrac{4\sqrt{150}\sqrt{189x}}{(\sqrt{189x})^2}\implies \cfrac{4\sqrt{(150)({189x})}}{189x}

\bf \cfrac{4\sqrt{28350x}}{189x}\qquad &#10;\begin{cases}&#10;28350=2\cdot 3\cdot 3\cdot 3\cdot 3\cdot 5\cdot 5\cdot 7\\&#10;\qquad 2\cdot 3^2\cdot 3^2\cdot 5^2\cdot 7\\&#10;\qquad 2\cdot (3^2)^2\cdot 5^2\cdot 7\\&#10;\qquad 2\cdot (3^2\cdot 5)^2\cdot 7\\&#10;\qquad 2\cdot (45)^2\cdot 7\\&#10;\qquad 14\cdot 45^2&#10;\end{cases}\implies \cfrac{4\sqrt{14\cdot 45^2}}{189x}&#10;\\\\\\&#10;\cfrac{4\cdot 45\sqrt{14}}{189}\implies \cfrac{180\sqrt{14}}{189x}\implies \cfrac{20\sqrt{14}}{21x}
