Step-by-step explanation:

6 / 3√5

= 2/√5

= 2√5/5

Answer:

 [tex]\frac{2\sqrt{5} }{5}[/tex]

Step-by-step explanation:

First, you can take a factor of (3) out of the numerator and denominator. This simplifies to equal 1, so you are left with 3/√5.

6 / 3√5   ----->   (3/3)  x  2/1√5  --->  (1)  x  2/√5  --->  2/√5

Because radicals should not be kept in the denominator, multiply both the numerator and denominator by the radical of 5. This removes the radical from the denominator while altering both the numerator and denominator equally. Remember, the square root of a number is technically the number raised to the 1/2 power. The 1/2 power times the 1/2 power equals the power of one, essentially "eliminating" the radical.

2/√5  --->  2/√5  x  √5/√5  --->  2√5 / 5

As there is not way to simplify further, your final answer should be [tex]\frac{2\sqrt{5} }{5}[/tex].

The property applied to the expression is (b) inverse property of multiplication

The expression is given as:

[tex]\frac{17}{3} * \frac{3}{17} = 1[/tex]

The numbers 17/3 and 3/17 are multiplicative inverses.

This means that the property applied to the expression is (b) inverse property of multiplication

Solving :

Answer:

7. m^21n^27

8. a^21b^28

Step-by-step explanation:

7. since m^7 raised to the 3rd power = m^( 7 * 3 ) = m^21

then  n^9 raised to the 3rd power = n^( 9 * 3 ) = n^27

your answer is m^21n^27

8. a^3 raised to the 7th power = a( 3 * 7 ) = a^21

b^4 raised to the 7th power = b( 4 * 7 ) = b^28

your answer is a^21b^28

[tex]\frac{3}{4}+\frac{7}{8}[/tex]

Find the Least Common Denominator (LCD) of [tex]\frac{3}{4},\frac{7}{8}[/tex] . In other words, find the Least Common Multiple (LCM) of 4,8.

Method 1: By Listing Multiples

List the multiples of each number.

Multiples of 4 : 4, 8, ...

Multiples of 8 : 8, ...

Find the smallest number that is shared by all rows above. This is the LCM.

LCM = 8

Method 2: By Prime Factors

List the prime factors of each number

Prime Factors of 4 : 2, 2

Prime Factors of 8 : 2, 2, 2

Find the union of these primes.

2, 2, 2

Multiply these numbers: 2 * 2 * 2 = 8 ---> This is the LCM.

LCM = 8

---> LCD = 8

Make the denominators the same as the LCD.

[tex]\frac{3\times 2}{4\times 2}+\frac{7}{8}[/tex]

Simplify. Denominators are now the same.

[tex]\frac{6}{8}+\frac{7}{8}[/tex]

Join the denominators.

[tex]\frac{6+7}{8}[/tex]

Simplify.

[tex]\frac{13}{8}[/tex]

Convert to mixed fraction.

[tex]1\frac{5}{8}[/tex]

B. Just saying, this is an estimate, yet it seems more logical.

Answer:

C = [tex]12\pi m[/tex]

A = [tex]36\pi m^2[/tex]

Step-by-step explanation:

I'm going to assume that the radius is 6m. The circumference of a circle is [tex]C = 2r\pi[/tex]. So we can plug in 6 for r and we get the circumference is [tex]12\pi m[/tex].

For area, the equation is [tex]A = \pi r^{2}[/tex]. So we can again plug in 6 for r and we get that the area is [tex]36\pi m^2[/tex].

If 6m is the diameter, then the circumference is [tex]6\pi m[/tex] and the area is [tex]9\pi m^2[/tex].

Answer:

The correct answer is the second one.

Step-by-step explanation:

68/5 - 18/5 = 50/5

50/5 simplified is 10

Making the second equation true.

Answer:

270

Step-by-step explanation:

 x = k/y     This is an inverse relationship with k = constant of proportion (or variation)

-9 = k/(-30)

k = -9  *  -30 = 270

Answer:

Constant of variation  = 270.

Step-by-step explanation:

y = k/x

-30 = k / -9

k = -30 * -9
