Final answer:

The simplified form of the expression  [tex]3 \sqrt(4x/5) \ is\ 6 \sqrt(5x) / 5[/tex]after performing the square root separately on the numerator and denominator, and then rationalizing the denominator.

Explanation:

The expression given is [tex]3 \sqrt(4x/5)[/tex]. To simplify this expression, we observe that the square root of 4 is a perfect square and equals 2. The square root of the fraction can be taken by applying the square root to the numerator and the denominator separately. Therefore, we have:

[tex]3 \times \sqrt(4) \times \sqrt(x) / \sqrt(5)[/tex]

Upon simplifying, we get:

[tex]3 \times 2 \times \sqrt(x) / \sqrt(5)[/tex]

This simplifies further to:

[tex]6 \sqrt(x) / \sqrt(5)[/tex]

However, it's not common to leave a square root in the denominator, so we can multiply both the numerator and the denominator by sqrt(5) to rationalize the denominator.

The final simplified form is:

[tex]6 \sqrt(5x) / 5[/tex]

Answer:

5 12/25

Step-by-step explanation:

The first step is to separate the whole number number from the decimal.

that would be 5

Next would to see in which place the decimal number is in. .48 is in the hundredths place so we put 48 over 100 like this 48/100

So now we have the whole number 5 and the fraction 48/100

Lastly we simplify the fraction. 48 divided by 2 and 100 divided by 2

This equals 24/50

This can be simplified even more

24 divided by 2 and 50 divided by 2

This equals 12/25

Then we put the whole number in front and your final answer is

5 12/25

Julia sent 401 text messages in the month of September.

To find the number of text messages Julia sent, we can set up an equation using the given information.

Let's assume she sent x additional messages.

The cost of the additional messages would be 20x.

Since her total cost is $24, we can write the equation:

8 + 20x = 24

Subtracting 8 from both sides gives:

20x = 16

Dividing both sides by 20 gives:

x = 0.8

Since x represents the additional messages sent, we can round it to the nearest whole number.

Therefore, Julia sent 1 additional text message.

In order to find the total number of messages sent, we can add the initial allowance of 400 messages to the additional message:

Total messages sent = 400 + 1 = 401 text messages.

Final answer:

Julia sent a total of 401 text messages in September.

Explanation:

Julia's text messaging plan costs $8 for the first 400 messages and $20 for each additional text message. To find out how many text messages she sent in September, we need to determine the number of additional text messages she sent beyond the first 400. Let's assume she sent x additional text messages. The additional cost for these text messages would be 20 * x. We can set up an equation to solve for x:

$8 + 20x = $24

Subtracting $8 from both sides gives:

20x = $16

Dividing both sides by 20, we get:

x = $16 / 20 = 0.8

Since we cannot have a fraction of a text message, Julia must have sent 1 additional text message beyond the first 400. Therefore, she sent a total of 401 text messages in September.

Answer:

The area of the parallelogram is [tex]3\frac{1}{8}ft^{2}[/tex]

Step-by-step explanation:

Remember that a mixed fractions are composed for a whole number, a numerator and a denominator. For example in the mixed fraction [tex]2\frac{1}{3}[/tex]: 2 is the whole number, 1 is the numerator and 3 is the denominator.

If you want to convert to a improper fraction you need to multiply the whole number by the denominator and add to the numerator. The result will be the numerator of the improper fraction. The denominator remains the same.

[tex]2\frac{1}{3}=\frac{(2*3)+1}{3} =\frac{7}{3}[/tex]

1. Convert the mixed fractions in the improper fraction type, as follows:

[tex]Base= 2\frac{1}{2}=\frac{5}{2} \\ \\Height= 1\frac{1}{4}=\frac{5}{4}[/tex]

2. Replace the data in the equation of a parallelogram

[tex]Area= Base*Height[/tex]

[tex]Area= Base*Height\\Area=\frac{5}{2}ft *\frac{5}{4}ft\\Solve...\\Area=\frac{25}{8}ft^{2}[/tex]

3. Convert the improper fraction in a mixed fraction

[tex]Area=\frac{25}{8}ft^{2}=3\frac{1}{8}ft^{2}[/tex]

The area of the parallelogram is [tex]3\frac{1}{8}ft^{2}[/tex]

Answer:

x = 10/19

Step-by-step explanation:

[tex]log(x)-log(2x-1) = 1\\log\frac{x}{2x-1}=log(10)\\\frac{x}{2x-1}=10\\x = \frac{10}{19}[/tex]

The solution to the equation log x - log(2x-1) = 1 is x = 10/19.

We have,

To solve the equation log x - log(2x-1) = 1, we can use logarithmic properties to simplify the equation.

First, we can apply the quotient rule of logarithms, which states that

log a - log b = log(a/b).

Applying this rule to the equation, we get:

log(x / (2x-1)) = 1

Next, we can rewrite the equation in exponential form, using the definition that log base a of b is equivalent to a raised to the power of the logarithm equals b.

In this case, the base is 10 since we are using common logarithms (log base 10):

[tex]10^1[/tex] = x / (2x-1)

Simplifying the left side, we have:

10 = x / (2x-1)

To eliminate the denominator, we can multiply both sides of the equation by (2x-1):

10(2x-1) = x

Expanding the left side:

20x - 10 = x

Now, we can isolate the variable x:

20x - x = 10

19x = 10

Dividing both sides by 19:

x = 10/19

Therefore,

The solution to the equation log x - log(2x-1) = 1 is x = 10/19.

#SPJ12

The expression equivalent to (2r2 + r - 1) - (3r2 + 48 - 5) is -r2 + r - 44.

To find the equivalent expression, we need to distribute the negative sign into the second set of parentheses.

Then, combine like terms.

The expression becomes: (2r2 + r - 1) - 3r2 - 48 + 5.

Combining like terms further, we have: 2r2 + r - 1 - 3r2 - 48 + 5

Now, combine the like terms again: (2r2 - 3r2) + r + (-1 - 48 + 5). Simplifying this gives us: -r2 + r - 44

Therefore, the expression equivalent to (2r2 + r - 1) - (3r2 + 48 - 5) is -r2 + r - 44.
