Answer:

It's irrational

Step-by-step explanation:

An irrational number can be written as a decimal, but not as a fraction. An irrational number has endless non-repeating digits to the right of the decimal point.

Answer:

Rational

Step-by-step explanation:

Irrational numbers go on FOREVER.

An example is

1. π

2.[tex]\sqrt{2}[/tex]

....

Surds are irrational. A surd is a square root of a number that goes on forever.

Some irrational numbers have recurring digits (repeating digits)

10/3 is an example:

3. 333333333333333333333333333333333333333333............

Answer:

[tex]c(ge + p) = n + j \\ \\ \frac{c(ge + p)}{(ge + p)} = \frac{n + j}{(ge + p)} \\ \\ { \boxed{ \boxed{c = \frac{n + j}{ge + p} }}}[/tex]

49.12 ft^2

Step-by-step explanation:

The triangle:

Area = 1/2 * base * height

= 1/2 * 6 * 8

Answer:

270

Step-by-step explanation:

by using the proportion rule:

let X be the number of qualified teachers then

1:2=X=540 i.e.

1/2 =  X/540

by cross multiplication,

540x1=2xX

540=2X i.e.

X=540/2

X=270

There are 270 qualified teachers.

To solve this, we would apply the knowledge of proportion.

It is simply a way of stating that two ratios are of equal measure.

For example, [tex]a:b = x:y[/tex] or [tex]\frac{a}{b} = \frac{x}{y}[/tex]

Applying the following proportion rule given that:

Ratio of qualified teachers to unqualified teachers is 1:2.

Number of unqualified teachers = 540

Let number of qualified teachers be represented by x.

Therefore:

[tex]\frac{1}{2} = \frac{x}{540}[/tex]

Cross multiply

[tex]2x = 540(1)[/tex]

Divide both sides by 2

[tex]\frac{2x}{2} = \frac{540}{2} \\x = 270[/tex]

Therefore, the number of qualified teachers is 270.

Answer:

13

Step-by-step explanation:

Since the angles form 180 degrees, it will be what the equation is equal to.

Make the equation:

8r + 5 + 5r + 6 = 180

Combine like terms:

8r + 5 + 5r + 6 = 180

13r + 5 + 6 = 180

13r + 11 = 180

Solve:

13r + 11 = 180

Step-by-step explanation:

Step 1 :

Quintina decided to increase the deduction percentage of her federal income tax rate from [tex]14\%[/tex] to [tex]16\%.[/tex]

Quintina gross pay per month is [tex]\$2,100[/tex]

[tex]16\%[/tex] is written in the decimal form.

[tex]=\frac{16}{100}[/tex]

[tex]=0.16[/tex]  × Gross pay

[tex]=0.156[/tex]  × [tex]2100[/tex]

[tex]=336[/tex]

Step 2:

Monthly net pay = Gross pay- Federal income tax - State Income Tax – social Security- Medicare.

Answer:

Step-by-step explanation:

In order for the total displacement to be zero, the amount of forward displacement must be equal and opposite to the amount of backward displacement. Since the steps are the same length, they must be equal in number.

Half of the 10 steps were forward, and the other half were backward.

  5 steps forward; 5 steps backward.

Math develops from an effort to model the real world. It would probably give you some insight into this problem if you were to physically take some steps to see how many forward and backward you would need to end where you start.

Answer:

11 months

Step-by-step explanation:

Let x = months

y = total cost

Since Fitness 19 charges $30 a month, we multiply x by 30 like this: 30x

$44 is already added on the cost, so the Fitness 19 equation will look like this:

y = 30x + 44

Since LA Fitness charges $25 a month, multiply x by 25 like this: 25x

$99 is already added to the cost, so the LA Fitness equation will look like this:

y = 25x + 99

We need to find the point where they are both the same

30x + 44 = 25x + 99

First, move like terms to one side by subtracting 25x from both sides

30x + 44 = 25x + 99

- 25x         - 25x

5x + 44 = 99

Then, subtract 44 from both sides

5x + 44 = 99

     - 44 - 44

5x = 55

Finally, isolate the variable, x, by dividing both sides by the coefficient, 5

5x/5 = 55/5

x = 11

  Equation of a linear function is defined by equation y = mx + b,

where m = slope of the line and b = y-intercept

  Linear model representing a function for the earning (y) to photograph the houses (x) will be,

y = 140x + 35

   Let the linear equation representing the earnings to photograph the houses,

y = mx + b

         If we graph a line with two variables, earnings from photography on y-axis and the number of houses at x-axis,

Slope of the line 'm' = [tex]\frac{\triangle y}{\triangle x}[/tex]

     If two points lying on the line are (2, 315) and (7, 1015).

Slope of the line 'm' = [tex]\frac{1015-315}{7-2}[/tex]

                                 = [tex]\frac{700}{5}[/tex]

                                 = 140

     Therefore, equation of the line will be,

y = 140x + b

       Since, (2, 315) lies on the line,

315 = 140(2) + b

315 = 280 + b

b = 35

       Now the equation will be,

y = 140x + 35

        Therefore, linear model representing a function of the earning (y) to photograph the houses (x) will be,

y = 140x + 35

9514 1404 393

Answer:

  123°

Step-by-step explanation:

Each of the parts of the trisected angle is equal to the others.

  ∠PQT = ∠TQS

  7x +6 = -2x +8y -13

  9x -8y +19 = 0 . . . . . . subtract the right-side expression

  ∠TQS = ∠RQS

  -2x +8y -13 = 5x +2y

  7x -6y +13 = 0 . . . . . . subtract the left-side expression

__

These equations can be solved by any of your favorite methods to give ...

  (x, y) = (5, 8)

Then the angle measures are ...

  ∠PQT = 7x +6 = 7(5) +6 = 41

  ∠TQS = -2x +8y -13 = -2(5) +8(8) -13 = 64 -23 = 41

  ∠RQS = 5x +2y = 5(5) +2(8) = 41

The measure of angle PQR is 3·41° = 123°.

_____

Additional comment

Using Cramer's rule, the solution is ...

  x = (-8(13) -(-6)(19))/(9(-6) -7(-8)) = 10/2 = 5

  y = (19(7) -13(9))/2 = 16/2 = 8

I prefer a method like this, or the graphical solution, when the numbers don't lend themselves to substitution or elimination.

__

Obviously, once we have found angle PQT, we can simply multiply it by 3 to find angle PQR. We chose to compute the values of the other angles as a check on our math.
