r^4/9 translated verbal expression

Answers

Answer:

The quotient of 4 and 9 raised to the power of r.

Step-by-step explanation:

The verbal translation of  [tex]r^{\frac{4}{9} }[/tex]  is r to the power four-tenths.

Given,

[tex]r^{\frac{4}{9} }[/tex]

We have a number r with power 4 / 9.

we need to translate it into verbal form.

What are exponents and power?

If a number is expressed in this form - [tex]A^{B}[/tex]

A = base and B = exponents.

We can say that a number has base A with exponents B.

There are many ways to verbally express a given number.

Example:

3 / 2 = 3 divide by 2.

[tex]6^{2}[/tex] = six to the power two.

3 x ( 3 + 2 ) = three multiplied with the addition of three and two.

7 x [tex]8^{3}[/tex] =  seven multiplied by 8 to the power three.

[tex]3^{\frac{1}{7} }[/tex] = three to the power of one-tenths.

We are given,

     [tex]r^{\frac{4}{9} }[/tex]

We can say that the base is r and the exponent is 4/9.

or

we can also say r to the power four-tenths.

Thus the verbal translation of  [tex]r^{\frac{4}{9} }[/tex]  is r to the power four-tenths.

whats 2/3x+3/7=1-4/7x​

Answers

Answer:

[tex]x=6/13[/tex]

Step-by-step explanation:

So we have:

[tex]\frac{2}{3}x+\frac{3}{7}=1-\frac{4}{7}x[/tex]

Remove all the fractions to make things simpler. To do so, we can multiply by the LCM of the denominators.

The denominators are 3 and 7.

The LCM of 3 and 7 is 21. Thus, multiply everything by 21:

[tex]21(\frac{2}{3}x+\frac{3}{7})=21(1-\frac{4}{7}x)[/tex]

Distribute:

[tex]\frac{42}{3}x+\frac{63}{7}=21-\frac{84}{7}x[/tex]

Simplify the fractions:

[tex]14x+9=21-12x[/tex]

Add 12x to both sides:

[tex]26x+9=21[/tex]

Subtract 9 from both sides:

[tex]26x=12[/tex]

Divide both sides by 26:

[tex]x=12/26[/tex]

Reduce:

[tex]x=6/13[/tex]

And that's our answer :)

Answer: x = 6/13

find the common denominator (21);

14/21x + 9/21 = 21/21 - 12/21x

move your variable to one side and your constants to the other:

26/21x = 12/21

multiply all by 21/26 to get a lone x:

x = 12/26

simplify:

x = 6/13

given the equation y = 2x - 8, find the ordered-pair solution when x = 4 and the ordered-pair solution when y = 4

Answers

Answer:

When x = 4, (4, 0)

When y = 4, (6, 4)

Step-by-step explanation:

To find the ordered-pair solution when x = 4, plug 4 into the x of the equation.

y = 2x - 8

y = 2(4) - 8

y = 8 - 8

y = 0

This produces the ordered pair (4, 0).

To find the ordered-pair solution when y = 4, plug 4 into the y of the equation.

y = 2x - 8

4 = 2x - 8

12 = 2x

6 = x

x = 6

This produces the ordered pair (6, 4).

Answers

Answer:

x = 5  when x >=-9

Step-by-step explanation:

| x + 9 | - 4 = 2x

x + 9 - 4 = 2x

x - 2x = 4 - 9

-x = - 5

x = 5

x < - 9 no solution

| x + 9 | - 4 = 2x

| -10 + 9 | - 4 = 2(-10)

| -1 | - 4 = -20

1 - 4 = -20

-3 = -20

x >= -9 no solution only x = 5

| x + 9 | - 4 = 2x

| -9 + 9 | - 4 = 2(-9)

| -1 | - 4 = -18

1 - 4 = -18

-3 = -18

Calculate the slope of the line on the graph

Answers

Answer:

3.5 (meters per second)

Step-by-step explanation:

To calculate the slope, we need two points. Let's see if we can select two points from the graph.

From the graph, we can pick out two possible points.

At the beginning, (0,2.5) is a valid candidate.

And at the end, with (5,20). Thus, let's use the slope formula to calculate the slope.

The slope formula is:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let (0,2.5) be x₁ and y₁ and let (5,20) be x₂ and y₂. Thus:

[tex]m=\frac{20-2.5}{5-0}[/tex]

Simplify:

[tex]m=\frac{17.5}{5}\\ m=3.5[/tex]

Thus, the slope is 3.5 meters per second.

Further notes:

And the entire equation will be:

[tex]m=3.5s+2.5[/tex]

It takes 22 minutes for 10 people to paint 10 walls. How many minutes does it take 14 people to paint 14 walls?

Answers

Answer:

22 minutes

Step-by-step explanation:

The number of minutes and number of people are inversely proportional but the number of people, minutes painted and walls painted are directly proportional. Therefore, it takes 10 people 22 / 10 = 2.2 minutes to paint 1 wall and 2.2 * 14 = 30.8 minutes to paint 14 walls. To find the time it takes 14 people to paint 14 walls, we can set up the following equation:

14 * x = 30.8 * 10 (where x is our answer)

x = 30.8 * 10 / 14 = 22 minutes

Additionally, an easier way to do this is to recognize that 1 person paints 1 wall when 10 people paint 10 walls in 22 minutes so as long as the number of people and walls are the same, it will always take 22 minutes.

Solve for x. 7/8(−32−48x)+36 =2/3(−33x−18)−10x

Answers

Isolate the variable by dividing each side by factors that don't contain the variable.

x  =  2

Answer:

x=2

Step-by-step explanation:

7/8(-32)-7/8(48x)+36=2/3(-33x)-2/3(18)-10x  

= -224/8-336x/8+36

=-66x/3-36/3-10x.  

Simplifying the fractions

-28-42x+36=-22x-12-10x.  

Combining like terms

-42x+8=-32x-12.  

Add 32x to both sides:  

-42x+8+32x=-32x-12+32x

-10x+8=-12.  

Subtract 8 from both sides:  

-10x+8-8=-12-8

-10x=-20.  

Divide both sides by -10:  

-10x/-10 = -20/-10

x=2.

What is the value of y when -5=y-7/9? A) -7 B) -11 C) -38 D) -52

Answers

Answer:

C) -38

Step-by-step explanation:

[tex]-5=y-7/9\\-5+7/9=y-7/9+7/9\\-38/9=y[/tex]

I guess closest answer is C

Rearrange the equation by subtracting what is to the right of the equal sign on both sides of the equation: y-(x-(7)/(9))=0

simplify 7/9

y- (x-7/9) = 0

2.1 subtracting a fraction from a whole

rewrite the whole as a fraction using 9 as the denominator

x=x/1=x•9/9
evaluate fraction: the fraction those granted looks different but has the same value as the whole.

common denominator: The equivalent fraction in the other fraction fault in the calculation share the denominator.

2.2 adding up The two equivalent fractions
Add the two equivalent fractions which now have a common denominator

combine the numberators together, put the sum of difference over the common denominator then reduce to the lowest terms as possible:
x•9-(7)/9 = 9x-7/9

y-(9x-7)/9=0

then adding up to the equivalent fractions
9y-9x+7/9=0

now to get rid of the denominator, multiple both sides
9y-9x+7/9•9=0•9
9y-9x+7=0

now this is the formula
Y tells us how far up the line goes
X tells us how far along
M is the slope
B is the Y-intercept

the X and Y intercepts and the slope are called the line properties. we shall now graph line 9y-9x+7=0

ANSWER IS

Slope=1.000
Y-intercept=-7/9
X-intercept=7/9

50-6/50 = 44/50 = 88%

Answer:88%

Step-by-step explanation:

Percent means out of hundred. If you try to find what percentage something is out of a larger number, you multiply the fraction by 100%.

Our fraction in this case is 44/50.

(44/50) × 100% simplifies to (using a common factor of 2) (22/25) × 100% (2 goes into 44 twenty-two times, and into 50 twenty-five times). 100 and 25 share a common factor of 25, so this fraction can further be simplified to (22/1) × 4% (25 goes into itself once, and into 100 four times). 22/1 is the same as 22. 22 × 4% = 88%. And that's your answer.

Find EF given E(-7, -2) and F(11, 3). Round your answer to the nearest thousandth (3 decimal places).

Answers

Answer:

Step-by-step explanation:

Given that :

E = (-7, - 2) ; x1 = - 7 ; y1 = - 2

F = (11, 3) ; x2 = 11 ; y2 = 3

EF = √((x2 - x1)² + (y2 - y1)²)

EF = √((11 - -7)² + (3 - -2)²)

EF = √((11 + 7)² + (3 + 2)²)

EF = √(18² + 5²)

EF = √324 + 25

EF = √349

EF = 18.6815

EF = 18.682 units (3 decimal places )
