Answer:

The radian measure of the central angle of the given circle is [tex]\frac{7}{19} rad[/tex]

Step-by-step explanation:

The radian measure of the central angle θ of a circle of radius r that intercepts an arc of length s can be calculated from the formula given below

s =rθ

where s is the length of arc

r is radius of the circle

and θ is the central angle in rad (radian)

From s = rθ, Then

θ = s / r

From the question,

Radius r = 19 feet

and Arc length s = 7 feet

Hence,

θ = s / r becomes

θ = 7 / 19

∴ θ [tex]= \frac{7}{19} rad[/tex]

This means the radian measure of the central angle of the given circle is [tex]\frac{7}{19} rad[/tex]

Answer:

Step-by-step explanation:

First you do the parentheses so the -3 x 8n= -24 and -3 x -5= 15

so it will look like this. -24n+15-2n=8n-21

Now combine like terms the -24n-2n.

-26n+15=8n-21 now subtract 8n now it will look like this

-34n+15=-21 now -15 from -21

-34n=-36

now if you want n by its self divide -34 and -36

Also called the circumflex, the caret is the symbol ( ^ ) above the 6 key on a standard qwerty keyboard.

In mathematics, the caret represents an exponent, such as a square, cube, or another exponential power.

Example attached below

Answer:

d = 81

Step-by-step explanation:

Solve for d:

36 = (4 d)/9

Hint: | Reverse the equality in 36 = (4 d)/9 in order to isolate d to the left hand side.

36 = (4 d)/9 is equivalent to (4 d)/9 = 36:

(4 d)/9 = 36

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of (4 d)/9 = 36 by 9/4:

(9×4 d)/(4×9) = 9/4×36

Hint: | Express 9/4×4/9 as a single fraction.

9/4×4/9 = (9×4)/(4×9):

(9×4)/(4×9) d = 9/4×36

Hint: | Express 9/4×36 as a single fraction.

9/4×36 = (9×36)/4:

(9×4 d)/(4×9) = (9×36)/4

Hint: | Cancel common terms in the numerator and denominator of (9×4 d)/(4×9).

(9×4 d)/(4×9) = (4×9)/(4×9)×d = d:

d = (9×36)/4

Hint: | In (9×36)/4, divide 36 in the numerator by 4 in the denominator.

36/4 = (4×9)/4 = 9:

d = 9×9

Hint: | Multiply 9 and 9 together.

9×9 = 81:

Answer: d = 81

Answer: d=81

Step-by-step explanation:

Given

36=4/9 d

Divide both sides by 4/9 (division property of equality)

d=36 ÷ (4/9)

Turn division of fraction into multiplication of its reciprocal

d=36 × (9/4)

Simplify

d=81

Answer:

Step-by-step explanation:

Given that the regular price for the specialty paper is

$6.88 per carton

and the company receives a discount of $1.75 per carton

this means that the company will pay  $6.88-$1.75 = $5.13 per carton

To calculate the cost of the supply for 24 cartons we have

24*5.13= $123.12

the cost of the supply is $123.12

alternatively we can also calculate the percentage discount as

Actual cost of 24 cartons= 24*6.88= $165.12

Discount= $6.88-$1.75 = $5.13 per carton

%discount= 1.75/6.88= 0.2543

= 25.43%

The price after discount is

=$165.12*(1-0.2543)

=$165.12*0.7456

= $123.12

[tex]\huge \boxed{11x^2 y^3-4xy^2 }[/tex]

Step-by-step explanation:

[tex](4x^2y^3 + 2xy^2 - 2y) - (-7x^2 y^3 + 6xy^2 -2y)[/tex]

Distribute the negative sign to the terms in the bracket.

[tex](4x^2y^3 + 2xy^2 - 2y) +7x^2 y^3 - 6xy^2 +2y[/tex]

Grouping like terms.

[tex](4x^2y^3 +7x^2 y^3) + (2xy^2 - 6xy^2 ) +( - 2y +2y)[/tex]

Combining like terms.

[tex](11x^2 y^3) + (-4xy^2 ) +(0)[/tex]

Answer:

[tex]x=21\textdegree[/tex]

Step-by-step explanation:

So we know that:

[tex]\angle A=3x-30 \text{ and}\\\angle B=2x-9[/tex]

And that the two angles are vertical angles.

Since they are vertical angles, their measurements are equivalent. Thus, to find x, set the equations equal to each other:

[tex]\angle A=\angle B\\(3x-30)=(2x-9)[/tex]

Now, solve for x. Add 30 to both sides. The left side cancels:

[tex](3x-30)+30=(2x-9)+30\\3x=2x+21[/tex]

Now, subtract 2x from both sides. The right cancels:

[tex](3x)-2x=(2x+21)-2x\\x=21[/tex]

Thus, the value of x is 21.

Answer: 5000

Step-by-step explanation:

Answer:

[tex]y=8[/tex]

RS: 77

ST: 46

Step-by-step explanation:

We know that RS and ST together make the line RT. This means the sum of their lengths will be equal to RT.

Since RT is 123, we can create the equation [tex]9y+5+5y+6=123[/tex].

Combining like terms gets us [tex]14y+11=123[/tex]

We can now solve for y by isolating the variable on one side of the equation.

[tex]14y + 11 - 11 = 123-11\\\\14y=112\\\\14y\div14 = 112\div14\\\\y=8[/tex]

Now we know the value of y. We can now substitute this into the expressions for RS and ST to find their values.

RS = [tex]9y+5\\\\(9\cdot8)+5\\\\72+5\\\\77[/tex]

ST = [tex]5y+6\\\\(5\cdot8)+6\\\\40+6\\\\46[/tex]

We can confirm this is correct because [tex]46+77=123[/tex].

Answer:

its called a Domain

Step-by-step explanation:

All of the x-values or inputs are called Domain.

"x-values" is the word used in mathematics and statistics to describe the input values or independent variables in a function or equation.

These x-values stand for a function's inputs, arguments, or the points at which a mathematical connection is being assessed.

The outputs or dependent variables of a function are represented by the appropriate y-values, which are often paired with the associated x-values. The link between the independent and dependent variables can be seen on a graph by plotting the x-values and y-values together as data points.

For example, in the equation y = 2x + 3, "x" represents the x-values or inputs, while "y" represents the corresponding y-values or outputs. By substituting different values for x, you can calculate the corresponding y-values and observe how changes in the x-values affect the relationship described by the equation.

Hence the answer is Domain.

Multiply both sides by 11:

[tex]11(3)=(11)\frac{q}{11}[/tex]

The right side cancels:

Answer:

(-8, 7); x + y = 13 → y= -x + 13

parallel lines have the same slope. slope is -1

y = -x + b

Step-by-step explanation:

The position of point P is at 0 on number line.

What is Number line?

Number line is a straight line with numbers placed at equal intervals.

Given that;

Point C is located at -4.

Point D is located at 6.

Now,

Distance between points -4 and 6 is,

6 - (-4) = 6 + 4 = 10

Since, Point P be located so that the directed line segment from C to D will be partitioned in a 2 : 3.

Let partitions are 2x and 3x.

Then,

2x + 3x = 10

5x = 10

x = 2

So, The partitions between point C and D is,

2x = 2 × 2 = 4

3x = 3 × 2 = 6

So, The ratio become = 4 : 6

Thus, Position of point P from C = - 4 + 4 = 0

Position of point P from D = 6 - 6 = 0

So, The position of point P is at 0 on number line.
