What is 6/9 as percent

Answer: 66.67

Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. If we want to write 6/9 as a percent, we need to find a fraction equivalent to 6/9 that has a 100 in the denominator. We can do this by setting up a proportion.

\frac{6}{9} = \frac{n}{100}

Now, we can use cross products to find the missing value.

9n = 600

÷9     ÷9

n = 66.67

Therefore, 6/9 can be written as 66.67%.

\huge\boxed{66.\overline{6}\%}

First, simplify the fraction by dividing the numerator and denominator each by 3. \frac{6}{9} \div \frac{3}{3} = \frac{2}{3}

\frac{2}{3} is a common fraction with an equivalent percentage of \boxed{66.\overline{6}\%}.

The .\overline{6} represents an infinitely repeating 6, as in .6666666666...

The answer is C

The equation has x = 8/10

To get X by itself you need to divide both sides by 8, so the equation should become X = 10/8

Multiply.
sergij07 [2.7K]

Answer:

D) 2x² + 4x - 30

Step-by-step explanation:

Follow the FOIL method:

FOIL =

First

Outside

Inside

Last

...and is the order you multiply to solve:

(x + 5)(2x - 6) =

(x)(2x) = 2x²

(x)(-6) = -6x

(5)(2x) = 10x

(5)(-6) = -30

Combine like terms. Simplify:

2x² -6x + 10x - 30 = 2x² (-6x + 10x) - 30 = 2x² + 4x - 30

2x² + 4x - 30 is your answer.

Add and simplify 1/5 + 1/10
aliya0001 [1]

In order to add these fractions we have to make a common denominator.

1/5 can turn into 2/10 Its the same thing. And its easier to solve with.

now lets multiply.

\frac{2}{10} × \frac{1}{10}

Now we add across

2 + 1 = 3

------------  

10 + 10 = 10 ( When adding fractions like these the denominator stays the same)

So your answer is...

\frac{3}{10}

Good Luck! :)

19. A quadratic equation is shown below.
victus00 [196]

Answer:

\{\sqrt b, -\sqrt b\}

Step-by-step explanation:

Given

a^2 - b = 0

Required

Determine the solution

Since b is  a perfect square, the equation can be expressed as:

a^2 - (\sqrt b)^2 = 0

Apply difference of two squares:

(a - \sqrt b)(a + \sqrt b) = 0

Split:

(a - \sqrt b)= 0 \ or\ (a + \sqrt b) = 0

Remove brackets:

a - \sqrt b= 0 \ or\ a + \sqrt b = 0

Make a the subject in both equations

a =\sqrt b \ or\ a  =-\sqrt b

The solution can be represented as:

\{\sqrt b, -\sqrt b\}
