What is the Lcd of 11/12 and 1/2

The percentage of the guests at this hotel who called for room service yesterday is 40%

When provided,

170 visitors in total requested room service.

The total number of visitors who did not request room service was 255.

We can now determine the overall number of guests.

Total guests equal (total guests who requested room services) plus (total number of guests who did not call for room services)

so,

there are overall guests of

=170+255

=425

We can now find the percentage

the proportion of visitors to this hotel who requested room service yesterday is

170/425 *100%

=40

The income tax can be paid by the teacher =$ 9212.

An income tax is a sort of tax that is levied on the earned and unearned income of an individual or corporation.

For instance, the United States levies a federal income tax on its residents, regardless of where they reside—in the country or overseas. The majority of the money the US government receives comes from this income tax.

Here we have

The annual salary of a teacher is $ 65,800

The rate of income tax = 14%

The income tax can be paid = 14% of 65800

Answer:

B. 80 degree

Step-by-step explanation:

These angles are same-side interior angles. Which means both angles have to add up to 180 degrees. One angle is 100 degrees; the other must be 80 degrees!

The true statement is (d) the angle measures of trapezoid PQRS are equal to the corresponding angle measures of trapezoid KLMN

From the question, we have the following parameters that can be used in our computation:

Trapezoid PQRS

The transformation is given as

As  a general rule of transformation, reflection and rotation are rigid transformations and they do not change the size and angles in a shape

This means that we get a congruent figure to that figure after the transformations

Thus, when PQRS is reflected and rotated 90° about the origin to form trapezoid KLMN, the trapezoid KLMN is congruent to trapezoid PQRS.

⇒  By the definition of congruence,

The corresponding sides and angle of trapezoid KLMN are congruent to that of trapezoid PQRS.

⇒ ∠P ≅ ∠K, ∠Q ≅ ∠L, ∠R ≅ ∠M and  ∠S ≅ ∠N

⇒ Option D) is correct.

Note:  KMLN is a trapezoid ⇒ Sum of the angle measures of trapezoid P'Q'R'S' is also 180°

Option A) is incorrect.

Since, trapezoid KMLN is congruent to trapezoid PQRS.

⇒ Option B) is incorrect.

We know that if two shapes are congruent then their area must be equal.

⇒ Area of trapezoid KMLN = Area of trapezoid PQRS

Thus, Option C) is incorrect.

To find an equivalent expression for the area of the cement walkway, we can first distribute the 32 on the right side of the equation to get 32(5x-1 + 8) = 32(5x-1) + 32(8). Then, we can subtract the area of the courtyard, 24(5x-1), from this expression to get 32(5x-1) + 32(8) - 24(5x-1) = 8(5x-1) + 32(8).

The formula of volume of a cuboid is given by

V = L * W * H

Substituting the values into the formula;

An equation for the line parallel to the given line that contains C(2,4) is y = (3/4)x + (1/2).

We may use the slope-intercept version of the expression of a line, which is provided by "y = mx + b," where m seems to be the slope of the line & b is the y-intercept, to express the linear function that is perpendicular to a given line as well as contains a particular point.

We may easily utilize the same value of m again for the equation of a parallel line if the slope-intercept form of a line's equation is provided. For instance, if the provided line's equation is "y = 2x + 1," a parallel line's equation would be "y = 2x + c," where c is a constant.

By restructuring the equation in slope-intercept form if the equation of a line is provided in another form, such as "ax + by + c = 0," it is possible to determine the slope of the line. If the expression of the single sequence is "3x - 4y + 5 = 0," for instance, we may rewrite it in slope-intercept form by focusing just on y on one side of the equation:

3x - 4y + 5 = 0

-4y = -3x - 5

y = (3/4)x + (5/4)

The slope of the line is 3/4.

4 = (3/4)(2) + b

4 = (3/2) + b

b = 4 - (3/2)

Answer:

750 ft

Step-by-step explanation:

the 2 situations are similar ( both right triangles ) with corresponding sides being in proportion.

let h be the height of the cell phone tower

We require the dimensions to be the same, using the conversion

1 foot = 12 inches , then

10 ft = 10 × 12 = 120 in

125 ft = 125 × 12 = 1500 in

then we obtain

[tex]\frac{h}{1500}[/tex] = [tex]\frac{120}{20}[/tex] =  6 ( multiply both sides by 1500 to clear the fraction )

h = 1500 × 6 = 9000 in ( divide by 12 to convert to ft )

h = 9000 in ÷ 12 = 750 ft

that is the cell phone tower is 750 ft tall.

The general form of an equation having vertex and point is y=a(x-h)²k. Then, the general form equation with the vertex of (-4,1) and point (-3,3) is y=3x²+24x+48.

The vertex form is an alternative way to state a parabola's equation. The equation y=a(x-h)²k is the formula for this, where k denotes the vertical translation, h is the horizontal translation, and a is a vertical stretch factor.

Here, given the vertex (h,k) is (-4,1) and the point (x,y) is (-3,3)

Start by substituting the values of h and k in the vertex equation, we get,

y=a(x+4)²(1)

Given that the point where the vertex meets is (-3,3). If we substitute this point into the equation above, we obtain,

3=a(-3+4)

a=3

To obtain the general form, now substitute the values of a and (h,k) in the vertex equation. We get,

y=3(x+4)²

y=3(x²+8x+16)

y=3x²+24x+48

Therefore, the required answer is y=3x²+24x+48.

Answer:

The observation in the upper right corner of the plot is influential for the least-squares regression line.

Step-by-step explanation:

The slower pipe if working alone can fill the tank in 10.5 hours.

A cuboid is a three-dimensional solid that has 6 faces (rectangular), 8 vertices, and 12 edges. A cuboid has three dimensions such as length, width, and height. A perfect cuboid is said to be a cuboid that has integer edges and the formula for its volume is: V = length ×breadth× width

Given here dimensions of the swimming pool as 30 feet long, 14 feet wide, and an average depth of 8 feet, therefore the volume of the swimming pool V = 30×14×8

  = 3360 feet³

Again the two pipes working together can fill the pool in 3.5 hours and let their speeds 2x and x then, their relative speed = 3x

thus we have 3.5 = 3360/3x

                  ⇒   x  = 320 feet³/hr

Therefore the individual speeds are equal to 320 feet³/hr and 640 feet³/hr

Accordingly, the time taken by the slower pipe to fill the entire tank alone is = 3360/320

             = 10.5 hours

Hence, the time taken by the slower pipe is 10.5 hours
