Using only a compass and a straightedge, you are constructing a line perpendicular to AB and passing through a given point, M, on AB. With a
compass of set width, you have drawn arcs that intersect AB on each side of M and marked the two intersection points as P and Q.
The next step in this construction is to place the compass needle on
P (or Q) and mark an arc roughly where M's reflection across AB is located.
How to use a compass?One tool for drawing circles is a compass. According to the circle's radius, which is drawn with a compass, the sizes of the circles vary.
A compass's handle is held in place by our thumb and forefinger. A circle is typically drawn using just one hand. Between the forefinger and thumb, the compass is turned.
Around this point, the pencil tip is rotated. The circle's radius is determined by the distance between the pencil tip and the compass needle. A ruler is used to set it. The gap can be adjusted by adjusting the angle between the compass's arms.
At that point of reflection (M'), arcs drawn from P and Q in M's approximate location across AB will intersect. As desired, the line passing through point M and perpendicular to AB will connect M and M'.

A cyclist rides into the country at an average speed of 10 miles per hour. When his bike gets a flat tire, he walks it back at an average speed of 3 miles per hour. If he returns home 6 and a half hours after he starts, how far into the country does he go?
The distance the cyclist traveled into the country, given that he rides into the country at an average speed of 10 miles per hour is 15 miles
How do i determine the distance traveled?Let the total distance traveled into the country be y.
Now, we shall determine the riding time. Details below:
Speed = 10 mile per hourDistance traveled = yRiding time = ?Riding time = Distance / speed
Riding time = y / 10
Next, we shall obtain the walking time of the cyclist. This is shown below:
Speed = 3 mile per hourDistance traveled = yWalking time = ?Walking time = Distance / speed
Riding time = y / 3
Finally, we shall obtain the total distance traveled. This is illustrated below:
Riding time = y / 10Riding time = y / 3Total time = 6.5 hoursTotal distance = y =?Total time = riding time + walking time
6.5 = y/10 + y/3
6.5 = (3y + 10y) / 30
6.5 = 13y / 30
Cross multiply
13y = 6.5 × 30
13y = 195
Divide both sides by 13
y = 195 / 13
y = 15 miles
Thus, the total distance traveled by the cyclist into the country is 15 miles.

What’s is the order pair for point B ?
The order pair of point B is (1.75,1.25).
What is order pair?
A pair that has two values stated in a specific order between parenthesis is known as an ordered pair. It is made up of the x coordinate (abscissa) and the y coordinate (ordinate). For greater visual comprehension, it helps to locate a point on the Cartesian plane. Two numbers in a specific order. Usually, parentheses are used to write this: (12,5)
This can be used to display a graph's position where the "x" (horizontal) value appears first and the "y" (vertical) value appears second.
(12,5) is therefore 12 units down and 5 units up.
Here the given point B is,
coordinate value of x axis= 1.75
coordinate value of y axis = 1.5
Then the order pair of point B is,
=> (x,y) =(1.75,1.5)
Hence the order pair of B is (1.75,1.25).

Area of triangle is, 351. 39 cm²
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
All the sides of triangles are,
⇒ 30 cm, 30 cm, and 26 cm
We know that;
⇒ Area of triangle = √ s (s - a) (s - b) (s - c)
Where, 's' is the semi perimeter of the triangle, and a, b and c are three sides of triangle.
Here, Sides are,
⇒ a = 30
⇒ b = 30
⇒ c = 26
Hence, We get;
⇒ s = (a + b + c) / 2
⇒ s = (30 + 30 + 26) / 2
⇒ s = 86 / 2
⇒ s = 43 cm
So, The area of triangle is,
⇒ Area of triangle = √ s (s - a) (s - b) (s - c)
⇒ Area of triangle = √ 43 (43 - 30) (43 - 30) (43 - 26)

a piece in a wooden toy set is a sphere of radius 7cm , with a cylindrical hole of radius 1cm drilled through the center. find the volume of this piece. write the exact answer. do not round.
The volume of the piece is: 4489.33
To find the volume of this piece, we need to subtract the volume of the cylindrical hole from the volume of the sphere.
The volume of the sphere is given by the formula: V = (4/3) * pi * r^3
Where r is the radius of the sphere, so in this case: V = (4/3) * pi * (7cm)^3 = 1436 * 3.14 cm^3 = 4511.32 cm^3
The volume of the cylinder is given by the formula: V = pi * r^2 * h
Where r is the radius of the cylinder and h is the height of the cylinder, since the hole is drilled through the center of the sphere, the height of the cylinder is equal to the radius of the sphere, so: V = 3.14 * (1cm)^2 * 7cm = 21.99 cm^3
So the volume of the piece is: 4511.32 - 21.99 = 4489.33 cm^3

Step-by-step explanation:
A common factor that all three numbers share is that they are divisible by 3, so we can factor 3 out. Typically, I take out the negative first:
-3(\(x^2-2x-3\)) (always remember to change signs!)
Now, we are left with \(x^2-2x-3\), and to factor that out, we need to find two numbers that add up to -2 and multiply to -3. These two numbers will be 1 and -3, so we can write our factor like this:
(x-3)(x+1)
Let's add back in the -3 from earlier to complete our factoring:
-3(x-3)(x+1)

Instructions: Determine the shape and direction of the parabola formed by the given function.
We have the parabola with equation y = 4x².
We have to determine the shape and direction of it.
If we compare it to the standard equation y = ax² + bx + c, we can see that a = 4, b = 0 and c = 0.
As the value of a is positive, the parabola will open upward.
The parameter has an absolute value greater than 1. This means that y increases "faster" relative to x that a parabola with a = 1.
This means that the parabola will be narrow about its line of symmetry which we call vertical strecth.
Answer:
Because a is positive the parabola opens upward.
Because a has an absolute value larger than 1 the parabola is narrow about its line of symmetry which we call vertical stretch.

Arianna's personal residence has an adjusted basis of $300,450 and a fair market value of $270,405. Arianna converts the personal residence to rental property. What is Arianna's gain basis
If Arianna decides to sell the rental property in the future, the gain or loss will be calculated based on the $270,405 gain basis.
The gain basis for Arianna's converted personal residence to rental property can be calculated by determining the lower value between the adjusted basis and the fair market value.
In this case, the adjusted basis is $300,450 and the fair market value is $270,405.
The gain basis is the lower of the two values, which in this case is $270,405. This means that the gain basis for Arianna's rental property is $270,405.
The gain basis is important for tax purposes as it is used to calculate the taxable gain or loss when the property is eventually sold.
If the property is sold for a higher price than the gain basis, there will be a taxable gain.
On the other hand, if the property is sold for a lower price than the gain basis, there will be a deductible loss.
In Arianna's case, if she decides to sell the rental property in the future, the gain or loss will be calculated based on the $270,405 gain basis.
It is important to note that there may be additional factors and adjustments that could affect the final tax calculations, such as depreciation deductions and any improvements made to the property.
Consulting a tax professional would provide more accurate and detailed information regarding the tax implications of selling the rental property.

A steel hex nut has two regular hexagonal bases and a cylindrical hole with a diameter of 1. 6 centimeters through the middle. The apothem of the hexagon is 2 centimeters. A cylinder is cut out of the middle of a hexagonal prism. The hexagon has an apothem with a length of 2 centimeters and base side lengths of 2. 3 centimeters. The prism has a height of 2 centimeters. The cylinder has a diameter of 1. 6 centimeters. The equation for the area of a regular hexagon = one-half (apothem) (perimeter). What is the volume of metal in the hex nut, to the nearest tenth? Use 3. 14 for π. 21. 1 cm3 23. 6 cm3 27. 6 cm3 31. 6 cm3.
To find the volume of metal in the hex nut, we need to calculate the volume of the hexagonal prism and subtract the volume of the cylindrical hole in the middle. The given measurements provide the necessary dimensions for these calculations. Answer : Compare the calculated volume to the options provided, and select the option that matches the closest value.
1. Calculate the volume of the hexagonal prism: The volume of a prism is given by the formula V = base area * height. The base area of the hexagonal prism can be calculated using the equation for the area of a regular hexagon (one-half * apothem * perimeter). Plug in the given values to find the base area and multiply it by the height of the prism.
2. Calculate the volume of the cylindrical hole: The volume of a cylinder is given by the formula V = π * (radius^2) * height. The radius of the cylindrical hole is half of the diameter given, so calculate the volume using the given diameter, height, and the value of π as 3.14.
3. Subtract the volume of the cylindrical hole from the volume of the hexagonal prism to find the volume of metal in the hex nut.
4. Round the final result to the nearest tenth.
5. Compare the calculated volume to the options provided, and select the option that matches the closest value.

Bob continues his research because even though there is no linear equation relationship between the number of bedrooms and selling price, there could be another type of relationship.
Bob continues his research because even though the correlation value he calculated between the number of bedrooms and the selling price was only 0.05, this does not necessarily mean that there is no relationship of any kind between these two variables. It simply means that there is no linear relationship between the two. There could still be other types of relationships between the two variables, such as an exponential or quadratic relationship. It is possible that further analysis and exploration of the data set would reveal such a relationship and allow Bob to uncover the relationship between the two variables.
