Answer:

14/21

Step-by-step explanation:

1. Find the value of x

Step 1: Write it as an equation.

  • \frac{2}{3}  = \frac{x}{21}

Step 2: Cross-multiply.

  • 2 * 21 = 3 * x
  • 3x = 42

Step 3: Divide both sides by 3.

  • \frac{3x}{3} = \frac{42}{3}
  • x = 14

2. Now that we know the numerator is 14 and the denominator is 21, we can write it as a fraction: 14/21.

What is the simplest form of 4 square root 81x^8y^5?
olasank [31]
Firstly,
thanks for posting this.

81 = 9x9 or 9 squared so at this stage I'm guessing the last two. 
x^ 8 = (x^ 4) x (x^ 2) (its called the multiplication rule of indices). 
Okay I have approx 14 mins to answer.
No panic
√ 81.x^8 x <span>√ y^5
</span>√ (9x^2 x 9x^6) x <span>√ y^5
</span>= 9x x <span>√ 9x^6 x  </span><span>√ y^5
</span>did I just gain time?
√ 9x^6 = <span>√ </span>3x ^3 x <span>√ 3x ^ 3
</span>or 2 . √ 3x^3. <span>√ y^5
</span>more time
okay, so that wasnt successful. 
√ 9x^6 =<span>√ </span> (3x^2) x <span>√ </span>(3x^4)

Find each measurement indicated. Round your answer to the nearest tenth.
Ksivusya [100]

The measure of the angle B is 30 degree after applying the sin law of triangle.

<h3>What is the triangle?</h3>

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

We have a triangle shown in the picture:

We can apply the sin law of the triangle to find the angle B

\rm \dfrac{28}{sin91} =\dfrac{14}{sinB}

SinB = 0.499

B  = 29.99 ≈ 30 degree

Thus, the measure of the angle B is 30 degree after applying the sin law of triangle.
