Exponent properties help us to simplify the powers of expressions.  The quotient of the given expression [tex]\dfrac{6 - 3(\sqrt[3]{6})}{\sqrt[3]{9}}[/tex] is (2∛3 - ∛18).

[tex]{a^m} \cdot {a^n} = a^{(m+n)}\\\\\dfrac{a^m}{a^n} = a^{(m-n)}\\\\\sqrt[m]{a^n} = a^{\frac{n}{m}}\\\\(a^m)^n = a^{m\times n}\\\\(m\times n)^a = m^a\times n^a\\\\[/tex]

Given to us

[tex]\dfrac{6 - 3(\sqrt[3]{6})}{\sqrt[3]{9}}[/tex]

We will solve the problem using the basic exponential properties,

[tex]\dfrac{6 - 3(\sqrt[3]{6})}{\sqrt[3]{9}}\\\\ = \dfrac{6}{\sqrt[3]{9}} - \dfrac{3(\sqrt[3]{6})}{\sqrt[3]{9}}\\\\ = (6\cdot 3^{-\frac{2}{3}}) - [3 \cdot (2 \cdot 3)^{-\frac{2}{3}}3^{-\frac{2}{3}}]\\\\= (2 \cdot 3 \cdot 3^{-\frac{2}{3}}) - [3 \cdot 2^{-\frac{2}{3}} \cdot 3^{-\frac{2}{3}}3^{-\frac{2}{3}}]\\\\[/tex]

[tex]= [2 \cdot 3^{(1-\frac{2}{3})}] - [2^{\frac{1}{3}}\cdot 3^{(1+\frac{1}{3} - \frac{2}{3})}]\\\\= [2 \cdot 3^{(\frac{1}{3})}] - [2^{\frac{1}{3}}\cdot 3^{(\frac{2}{3})}]\\\\= 2\sqrt[3]{3} - \sqrt[3]{2}\sqrt[3]{9}\\\\=2\sqrt[3]{3} - \sqrt[3]{18}[/tex]

Hence, the quotient of the given expression [tex]\dfrac{6 - 3(\sqrt[3]{6})}{\sqrt[3]{9}}[/tex] is (2∛3 - ∛18).

Step-by-step explanation:

FBI agents use them I think

3(7x + 1)

3 . 7x = 21x

3.1 = 3

3(7x + 1 ) = 21x + 3

The equivalent expression with the fewest symbols possible is 21x+ 3.

The distributive Property states that it is necessary to multiply each of the two numbers by the factor before performing the addition operation when a factor is multiplied by the sum or addition of two terms.

we have,

3 x (7x+ 1)

By Distributive property we know

a x( b+ c) = a x b + a xc

ax (b-c) = a x b - a x c

So, 3 (7x + 1 )

= 3 (7x)+ 3(1)

= 21x + 3

Answer:

Step-by-step explanation:

6. x + 21 = 56

→ x = 56 – 21

→ x = 35

7. n – 13 = 8

→ n = 8 + 13

→ n = 21

8. w – 7 =41

→ w = 41 + 7

→ w = 48

9. b + 22 = 89

→ b = 89 – 22

→ b = 67

10. z – 53 = 26

→ z = 26 + 53

→ z = 79

6.4% of the lights are faulty

Step-by-step explanation:

Well you can make a proportion out of this question.
so lets do faulty/total

16/250 = x/ 100

Since x/100 is basically finding the percent since percent means out of a hundred.

Cross multiply to solve.

250x= 1600

SOlve for x

X=6.4

6.4 percent of the lights are faulty.

Answer:

30feet= 91.5 centimeters

The total of cm in the 1 yard based upon  30.5 centimeters in a foot will be 91.5 centimeters.

Multiplication is the general procedure in mathematics in which we multiply two or more numbers to each other to find a new multiplied number.

In another word, multiplication is nothing but changing one value by-product of another value

Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.

Given that

1 feet = 30.5 centimeters

Given that

1 yard = 3 feet

Hence 1 yard = 3 × 30.5 centimeter.

1 yard = 91.5 centimeters hence in 1 yard there will be 91.5 centimeters

Step-by-step explanation:

We have to use the Pythagorean theorem here

Statue is 3.4 tall, that's one leg of the right traingle

Braden is 8 meters away, that's the longer leg of the right triangle

the hypotenuse would be the distance between Braden's head and the top of the statue (let's assume it is X )

x^2 = 3.4^2 + 8^2 = 11.56 + 64 = 75.56

Answer:

y = - 3x - 2

Step-by-step explanation:

The function is linear and can be expressed in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (- 1, 1) ← 2 ordered pairs from the table

m = [tex]\frac{1-4}{-1-(-2)}[/tex] = [tex]\frac{-3}{-1+2}[/tex] = [tex]\frac{-3}{1}[/tex] = - 3 , then

y = - 3x + c

To find c substitute any ordered pair into the equation

using (0, - 2 ) , then

- 2 = - 3(0) + c = 0 + c ⇒ c = - 2

y = - 3x - 2 ← function rule

y = - 3x - 2
