​

Step-by-step explanation:

take ∆PRT

angle prt = 30°(||sides, traversal, opp angles)

angle ptr = 45+y(|| sides, opp angles)

x+30+45+y = 180

x+y = 180-75= 105

x= 105-y

take triangle zrt

angle zrt =30(parallel sides and traversal with opp angles)

angle ztr = y(parallel lines)

30+y+w = 180

w = 150-y

angle pzt+azr = 360-300+2y=60+2y

pzt= 30+y

triangle pza

30+y + 45+30= 180

y = 180-105=75

w = 75

x=30

Answer:

false

Step-by-step explanation:

the domain can be discrete or continuous

The measure of the angle at which the poles meet at the top of the tepee is 180 degrees

Complementary angles are angles which sum is equals to 90 degrees. Two angles complement each other when there sum is 90 degrees.

The two poles meet at the top of the tepee.

The angle at which they meet is equals to twice the complement of the angles that the poles form with the ground. Therefore,

Complement of the angles that the poles form on the ground = 90°

Then the measure of the angle at which the poles meet at the top of the tepee is as follows:

Therefore, the measure of the angle at which the poles meet at the top of the tepee is 180 degrees

Answer:

The solution to this system of equations is (-1, 1).

Step-by-step explanation:

A system of equations is a "a finite set of equations for which common solutions are sought". Or, they are a pair (or more) of equations that either intersect, are parallel, or the same line. For the sake of simplicity, we are going to focus on systems of equations that intersect and only have one solution.

A solution to a system of equations that intersect is represented by a point (x, y). This makes sense because at the intersection of two points, there lies a point.

So how do we find this point? We do this by solving the system of equations. We show that there exists a point in which two lines can be satisfied simultaneously. But how can we do that? Trial and error?! Well, no. There are some ways of approaching this.

The first method is graphing. By either using an external source or doing it yourself, graphing two lines and showing where they intersect is one of the more understandable ways of solving a system of equations. The point where they cross is the solution of the system.

The second method is elimination. This is observing that a system of equations can be combined together to eliminate a variable (x or y) and solving for the other in a one-variable equation. For example, say that I have this system of equations:

x - y = 1

x + y = 1

By simply adding the two together, I get:

2x = 2

x = 1.

Since we already have x = 1, we can substitute it back into one of the original equations to get y.

1 + y = 1

y = 0.

So, the solution to this system of equations would be (1, 0). Speaking of substituting ...

The third method is substitution. This is observing that a variable (x or y) can be written in terms of the other and then using that to substitute in and make one of the equations one-variable.

y = 2x + 3

x - y = -2

We can see that y is already in terms of x in the first equation, so let's substitute y for 2x + 3 in the second equation.

x - (2x + 3) = -2

- x - 3 = -2

- x = 1

x = -1

We can substitute x back into one of the original equations.

y = 2(-1) + 3

y = -2 + 3

y = 1

Therefore, the solution to this system of equations is (-1, 1).

[tex]6 \times 27 \times 28 \times 23 \times 3 = 312984[/tex]

Answer:

312984

Step-by-step explanation:

To solve the equation 6 x 27 x 28 x 23 x 3, you can follow these steps:

Start by multiplying the first two numbers: 6 x 27 = 162.

Then multiply the result by the next number: 162 x 28 = 4536.

Continue multiplying by the next number: 4536 x 23 = 104328.

Finally, multiply by the last number: 104328 x 3 = 312984.

The final result is 312984

Answer:

Y=-2X

Step-by-step explanation:

The equation of the line that passes through points (0, 0) and (-4, 8) is

y = -2x.

Option F is the correct answer.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

To find the equation of a line given two points, we can use the point-slope form of the equation of a line:

[tex]y - y_1 = m(x - x_1)[/tex]

where m is the slope of the line and (x_1, y_1) are the coordinates of one of the points on the line.

Given the coordinates (0, 0) and (-4, 8), we can find the slope of the line:

[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]

= (8 - 0) / (-4 - 0)

= -2

Now that we have the slope of the line, we can choose one of the points to plug into the point-slope form.

Let's use (0, 0):

[tex]y - y_1 = m(x - x_1)\\y - 0 = -2(x - 0)\\y = -2x[/tex]

Therefore,

The equation of the line that passes through points (0, 0) and (-4, 8) is

y = -2x.

Answer:

1/x+2

Step-by-step explanation:

1/x−2 + 4/4-X^2

​

Factor 4−x^2

1/x−2  +  4/(x−2)(−x−2)

To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x−2 and (x−2)(−x−2) is (x−2)(−x−2).

Multiply :  1/x−2 TIMES −x−2/−x−2

−x−2/(x−2)(−x−2)  +  4/(x−2)(−x−2)

​Since  −x−2/(x−2)(−x−2) and  4/(x−2)(−x−2)  have the same denominator, add them by adding their numerators.

−x−2+4​/(x−2)(−x−2)

Combine like terms in −x−2+4.

−x+2/(x−2)(−x−2)

Extract the negative sign in −x+2.

−(x−2)/(x−2)(−x−2)

Cancel out x−2 in both numerator and denominator.

=====================================================

Explanation:

Check out the diagrams below.

We'll start with the left diagram (marked "before") which is a right triangle with the horizontal leg of 25 feet and hypotenuse 65 feet.

Use the pythagorean theorem to find the vertical side x.

a^2 + b^2 = c^2

25^2 + x^2 = 65^2

625 + x^2 = 4225

x^2 = 4225 - 625

x^2 = 3600

x = sqrt(3600)

x = 60

The top of the ladder is 60 feet high when placed against the wall in this configuration.

------------------

If the upper end is moved down 8 feet, then x-8 = 60-8 = 52 feet is the new height of the ladder. Refer to the "after" in the diagram below.

Like earlier, we'll use the pythagorean theorem to find the missing side.

a^2 + b^2 = c^2

y^2 + 52^2 = 65^2

y^2 + 2704 = 4225

y^2 = 4225 - 2704

y^2 = 1521

y = sqrt(1521)

y = 39

The horizontal distance from the ladder base to the wall is now 39 feet.

Earlier it was 25 feet, so it has increased by 39-25 = 14 feet.

Polynomials consist of both indeterminates and coefficients. The polynomial that is been represented by the algebra tiles is 2x²-4x -6.

A polynomial consists of both indeterminates and coefficients and involves mathematical operations such as addition, subtraction, multiplication, and division.

In order to find the polynomial that is been represented by the tiles, we will simply, calculate the number of tiles for each variable,

As we can see in the image,

Number of tiles labeled as x² = 2

Number of tiles labeled as -x = 4

Number of tiles labeled '-' = 6

therefore, the polynomial can be written as 2x²-4x -6.

Hence, the polynomial that is been represented by the algebra tiles is 2x²-4x -6.

Answer:

The pool manager pay for each item is $60.6.

Step-by-step explanation:

Given:

A pool manager balances the ph level of a pool.

The price of a bucket of chlorine tablets is $90, and the price of a ph test kit is $11.

The manager uses a coupon that applies a 40% discount to the total cost of the two items.

Now, to find the money the pool manager pay for each item.

The price of a bucket of  chlorine tablets is = $90.

The price of a ph test kit = $11.

So, to get the total price of both items we add both prices:

Total cost of two items = $101.

As, given a coupon that applies a 40% discount to the total cost of the two items.

Now, to get the total cost by applying discount:

Thus, the pool manager pay = $60.6.

Therefore, the pool manager pay for each item is $60.6.

Answer:

A = 220 cm²

Step-by-step explanation:

Area of the rectangle = 11 x 18 = 198 cm²

Area of the triangle = 1/2 x (18 - 7) x (15 - 11) = 22 cm²

Therefore, area of the polygon = 198 + 22 = 220 cm²

Answer:

220 is The Correct Answer

Letter Choice (A)

Step-by-step explanation:

HERE'S MY PROOF AND MY RESEARCH

Area of a rectangle = width x height

Area of a triangle = 1/2 x base x height

Area of the rectangle = 11 x 18 = 198 cm²

Area of the triangle = 1/2 x (18 - 7) x (15 - 11) = 22 cm²

Therefore, area of the polygon = 198 + 22 = 220 cm²
