Answer:

B. Non-Proportional

Step-by-step explanation:

Any proportional relationship will include (0, 0) as a possible (input, output) pair. Here, the one-time fee of $10 means the output for 0 hours is not 0, but is 10. That is (0, 10) is a pair in the relationship, not (0, 0).

The relationship is non-proportional.

Answer:

Step-by-step explanation:

Let the number of hours spent by a costumer be X

As X increases the number of hours increases

It's a proportional relationship. If we draw the graph we see it .

Write the expression using rational exponents. Then simplify and convert back to radical notation.

ioda

Answer:

The radical notation is $3x\sqrt[3]{y^2z}$

Step-by-step explanation:

Given

$\sqrt[3]{27 x^{3} y^{2} z}$

Step 1 of 1

Write the expression using rational exponents.

$\sqrt[n]{a^{m}}=\left(a^{m}\right)^{\frac{1}{n}}$

$=a^{\frac{m}{n}}:\left({27 x^{3} y^{2} z})^{\frac{1}{3}}$

$(a \cdot b)^{r}=a^{r} \cdot b^{r}:(27)^{\frac{1}{3}}\left(x^{3}\right)^{\frac{1}{3}} \cdot\left(y^{2}\right)^{\frac{1}{3}} \cdot(z)^{\frac{1}{3}}$

$=$(3^3)^{\frac{1}{3}}\left(x^{3}\right)^{\frac{1}{3}} \cdot\left(y^{2}\right)^{\frac{1}{3}} \cdot(z)^{\frac{1}{3}}$$

$=\left(3\right)\left(x}\right)} \cdot\left(y}\right)^{\frac{2}{3}} \cdot(z)^{\frac{1}{3}}$

$=3x \cdot(y)^{\frac{2}{3}} \cdot(z)^{\frac{1}{3}}$

Simplify $3 x \cdot(y)^{\frac{2}{3}} \cdot(z)^{\frac{1}{3}}$

$=3 x \sqrt[3]{y^{2} z}$

14.4% of what number is 10.4

Helga [31]

First, convert "of" to x and put this info into an equation:

Let n represent the unknown number.

14.4 % x n= 10.4
n = 10.4 / 14.4%
n = 72.22222
n = ~72

Hope this helps!

What is the greatest common factor of 15x^3y^2 and 20x^4y^4?

Vanyuwa [196]

<h3>What is the greatest common factor of 15x³y² and 20x⁴y⁴? </h3>

First we have to find the factors of 15x³y²

15x³y² = 3 * 5x³y²

Then we have to find the factors of 20x⁴y⁴

20x⁴y⁴ = 2²x¹y² * 5x³y²

Now we have to find the common factors to both numbers.

The common factors are 5x³y²

Answer : GCF = (15x³y²,20x⁴y⁴) = 5x³y²

Hope this helps!

Solve for v -7 v+3 = -63

denis23 [38]

Answer:

v = 66/7

Step-by-step explanation:

Step 1: Write equation

-7v + 3 = -63

Step 2: Solve for v

Subtract 3 on both sides: -7v = -66

Divide both sides by -7: v = 66/7

Step 3: Check

Plug in x to verify if it's a solution.

-7(66/7) + 3 = -63

-66 + 3 = -63

-63 = -63
