The true condition is A. SU+UT= RT.

We have given that,

A line contains the following points left to right: R, T, U, S. The space between R and T is 12 units. The space between R and S is 24 units.

If TU = 6 units,

We have to determine the true statement,

A line is a straight one-dimensional figure that does not have a thickness, and it extends endlessly in both directions.

Question:

Find the surface area of the following figure below. Use 3.14 for pi

Answer:

Step-by-step explanation:

The circle has the same value of the side which is 3 so the length and width is 3 too. So the formal is L x W = Area. So this means 3 x 3 = 9

Answer:

(11/2)² or 121/4 would be added to the equation x ² +11x+30=0,  to "complete the square".

Step-by-step explanation:

x 2 +11x+30=0

Write the equation in the form of the square

(x)^2 + 2(x) (11/2)  + (11/2)^2  + 30 - 121/4= 0

Square of the first element + 2 into first element into 2nd element + square of 2nd element gives the complete square formula.

How we obtained the second element?

The mid term broken must always be equal to the mid term given.

Hence

2(x)    can only be equal to 11x if we multiply it by 11 and divide it with 2.

So the second term must be 11/2 .

To complete the square this second term ( 11/2)² is added and then subtracted to keep the equation equal to the original equation.

(x)^2 + 2(x) (11/2)  + (11/2)^2  + 30 - 121/4= 0

Putting it in the form of square

(x+ 11/2)^2  + 120-121/4= 0

Taking LCM and solving

(x+ 11/2)^2   - 1/4= 0

(x+ 11/2)^2  = 1/4

Taking square root on both sides

(x+ 11/2)   = ± 1/2

x= - 11/2  ± 1/2

x= -10/2= -5

x= -12/2= -6

Answer:

0.512 = 51.2%

1.94 = 194%

0.9 = 90%

1.33 = 133%

1.14 = 114%

1.42 = 142%

Step-by-step explanation:

 To convert a decimal to a percent, move the decimal point two spaces to the right.

 Converting a percent to a decimal works the same way, except you move the decimal two spaces to the left.

[Note: If there aren't enough numbers to go over two spaces, place a zero at the end. For example, if you have 0.9, and you need to convert it into a percent, you'd place a zero after the 9, making it 0.90.]

Answer:

600ft²

Step-by-step explanation:

Oh boy, this is gonna be a long one, so proceed with caution:

So we're gonna start with the one to the very left, we can split this into three different rectangles:

So we got the length of the bottom minus the length we don't want there because we're doing the big rectangle:

35 - 10 = 25

25 x 20 = 500

So we're just gonna keep that on a back burner, cause now we gotta do the two smaller ones:

So we got the measure from the one side, but we gotta subtract the 10 from the other side:

20 - 10 = 10

10 x 10 = 100

Now we gotta add that all up:

500 + 100 = 600

So the area of the first shape is 600ft²

Answer:

[tex]x = -2[/tex]

Step-by-step explanation:

Given

[tex]y=\frac{-3}{(x+2)^2}+3[/tex]

[tex]y = - 3[/tex]

[tex]y = 0[/tex]

The question has confusing details because the height of a shape do not relate to the given parameters.

A more complete question found on the brainly shows that the complete question asks for the asymptote of the function.

To do this, we have:

[tex]y=\frac{-3}{(x+2)^2}+3[/tex]

Take LCM

[tex]y = \frac{-3 + 3(x+2)^2}{(x+2)^2}[/tex]

Equate the denominator to 0

[tex](x + 2)^2 = 0[/tex]

Take square roots of both sides

[tex]x + 2 = 0[/tex]

Solve for x

[tex]x = -2[/tex]

Hence, the asymptote is at [tex]x = -2[/tex]

Answer:

150

Step-by-step explanation:

Answer:

Option B

Step-by-step explanation:

It's given that p + q has a value of [tex]\frac{12}{5}[/tex]

So the equation representing the relation will be,

p + q = [tex]\frac{12}{5}[/tex] --------(1)

Value of p is [tex]\frac{4}{5}[/tex]

p = [tex]\frac{4}{5}[/tex]

By substituting the value of p in the equation (1),

[tex]\frac{4}{5}+q=\frac{12}{5}[/tex]

q = [tex]\frac{12}{5}-\frac{4}{5}[/tex]

q = [tex]\frac{8}{5}[/tex]

Therefore, Option B will be the correct option.

Answer:

[tex] \boxed{A ≈ 58.1 \: cm^{2}} [/tex]

Step-by-step explanation:

When given a regular polygon.

s = a × 2 tan (π / n [radians]).

s = a × 2 tan (180 / n [degrees])

A = (n × s × a) / 2

Where s is the side length, n is the number of sides, a is the apothem length, and A is the area.

You may also see A = p × a.

Where p is the perimeter, the perimeter is the same as n × s.

The apothem is also known as the inradius.

______________________________________

Given a regular pentagon which has 5 sides, and an apothem of 4 cm.

s = 4 × 2 tan (180 / 5) = 4 × 2 × (0.726542528) = 8 × (0.726542528) = 5.81234022404.. ≈ 5.8 cm.

Now that we have sufficient information, we can now solve for the area.

A = (n × s × a) / 2

A = (5 × 5.81234022404.. cm × 4) / 2

A = (20 × 5.81234022404.. cm) / 2

A = (116.236804481.. cm²) / 2

A = 58.1234022404.. cm²

A ≈ 58.1 cm²

The area of the regular polygon is the amount of space it covers

The area of the regular polygon is 58.1 square centimeter

The given parameter is:

[tex]\mathbf{a=4}[/tex]

Start by calculating the side lengths using

[tex]\mathbf{s = 2a\ tan (\frac{180}{ n} )}[/tex]

Where n represents the number of sides.

In this case

[tex]\mathbf{n =5}[/tex]

So, we have:

[tex]\mathbf{s = 2a\ tan (\frac{180}{ 5} )}[/tex]

[tex]\mathbf{s = 2a\ tan (36)}[/tex]

Substitute 4 for (a)

[tex]\mathbf{s = 2 \times 4\ tan (36)}[/tex]

[tex]\mathbf{s = 8\ tan (36)}[/tex]

[tex]\mathbf{s = 5.8123}[/tex]

The surface area is then calculated as:

[tex]\mathbf{A = \frac{n \times s \times a}{ 2}}[/tex]

So, we have:

[tex]\mathbf{A = \frac{5 \times 5.8123 \times 4}{2}}[/tex]

[tex]\mathbf{A = 58.123}[/tex]

Approximate

[tex]\mathbf{A = 58.1}[/tex]

Hence, the area of the regular polygon is 58.1 square centimeter

Answer:

The dimension of the sandbox is (2x+1) by (x - 3)

Step-by-step explanation:

It seems the complete question will be:

The area of sandbox in park is represented by 2X^2-5x-3 find the dimensions of the sandbox in terms of x.

Step-by-step explanation:

From the question, the given expression is 2X^2-5x-3. This can be rewritten as

[tex]2x^{2} -5x-3[/tex]

If the area of the sandbox in park is represented by this expression, then the dimensions of the sandbox will be the product of the factors. To determine the factors, we will factorize the given quadratic expression.

Factorizing the expression [tex]2x^{2} -5x-3[/tex], we get

[tex]2x^{2} -6x+x-3[/tex]

[tex]2x(x-3)+1(x-3)[/tex]

[tex](2x+1)(x-3)[/tex]

Hence, the dimension of the sandbox is (2x+1) by (x - 3)
