How many types of coordinate system are in Revit?
There are three types of coordinate systems in Revit: Project Coordinates, Shared Coordinates, and Site Coordinates.
There are three types of coordinate systems in Revit: Project Coordinates, Shared Coordinates, and Site Coordinates. Project Coordinates are the default coordinates used in Revit and are based on the project origin. This is the origin point of the model and all elements in the project are positioned relative to this point.
Shared Coordinates are used to link multiple projects together. This origin point is determined by a shared coordinate system, which is based on the origin of the shared coordinate system.
Site Coordinates are used to set the project origin in the real-world location of a site. This location is determined by the user and the coordinate values can be set in the Site Location dialog box. All elements in the project are then positioned relative to this real-world site location.

At a new Italian restaurant, you order a salad for $3.50 and baked ziti for $9.25. If you want to leave a 15% tip, how much money should you leave for the waiter as tip?
Answer:
The total cost of the salad and baked ziti is $3.50 + $9.25 = $12.75
To calculate the tip, you need to multiply the total cost by the tip percentage (expressed as a decimal)
Tip = $12.75 x 0.15 = $1.91
So you should leave $1.91 as a tip for the waiter.

Answer: (5, -2)
Step-by-step explanation:
They give you two equations with two variables. You can solve this using elimination or substitution. However, it seems as though the problem wants you to do it through elimination. On the right, you have the equation
6x + 10y = 10
+ -6x - 24y = 18
After add these equations, you get -14y = 28. By dividing both sides by -14, you get y = -2. You can plug y = -2 back into either one of the original equations, and solve for x.
x = 5.
So your answer is (5, -2)
Are all lines of longitude measured in degrees north and south of the prime meridian?
No , all lines of longitude are not measured in degrees north and south of the prime meridian
Lines of longitude run north to south and measure places expressed in degrees east or west of the Prime Meridian.The basic work of the longitude lines is to show the distance at which a place lies, east or west of the Prime Meridian.
Longitude is a measurement of location east or west of the prime meridian at Greenwich, London, England, the specially designated imaginary north-south line that passes through both geographic poles and Greenwich. Longitude is measured 180° both east and west of the prime meridian.
Any location's distance from the equator may be determined using its latitude, which is based on its degree. We can locate any point on Earth using longitude and latitude. The GPS or Global Positioning System uses these coordinates.
The grid system that enables us to locate absolute or precise places on the surface of the Earth is made up of latitude and longitude. Latitude and longitude can be used to pinpoint certain locations. Landmark identification also benefits from knowledge of latitude and longitude

Answer:
69.9° or 110.1°
Step-by-step explanation:
You want to know the angle opposite the side of length 22 in a triangle in which a 28° angle is opposite a side of length 11.
Law of SinesThe law of sines tells you ...
sin(B)/b = sin(A)/a
sin(x)/22 = sin(28°)/11
sin(x) = 22/11 · sin(28°)
x = arcsin(2·sin(28°)) ≈ 69.9° or 110.1°

If he works 14 hours then he will earn the amount of $105 which is true and if he works 16 hours then he will earn $120 which is true.
What is the Linear equation?You should be aware that a linear equation is defined as an equation in which the highest power of the variable is one.
The given graph represents Elisa's work and the amount of money he earns at his job.
According to the given graph,
We can see two points are (4, 30) and (8, 60)
The linear equation will be
⇒ y - 30 = (60-30)/(8-4)(x-4)
⇒ y - 30 = (30)/(4)(x-4)
⇒ y - 30 = 7.5(x-4)
⇒ y = 7.5x - 30 + 30
⇒ y = 7.5x
Elisa's work = 14 hours then we verify the response by substituting x = 14 in the above equation,
⇒ y = 7.5(14)
⇒ y = 105
Thus, if he works 14 hours then he will earn $105
Elisa's work = 16 hours then we verify the response by substituting x = 16 in the above equation,
⇒ y = 7.5(16)
⇒ y = 120
Thus, if he works 16 hours then he will earn $120.

Prove the segments joining the midpoint of consecutive sides of an isosceles trapezoid form a rhombus. Find the slope of ef and gd.
The slope of ef and gd can be found by using the formula: slope = (y2 - y1) / (x2 - x1) where ef = (x1, y1) and gd = (x2, y2) are the coordinates of the points e and g.
Isosceles Trapezoid Form A RhombusA rhombus is a quadrilateral with all sides equal in length. To prove that the segments joining the midpoint of consecutive sides of an isosceles trapezoid form a rhombus, we can use the following properties of an isosceles trapezoid:- The two bases (the parallel sides) are congruent.
- The two legs (the non-parallel sides) are congruent.
- The diagonals of the trapezoid bisect each other.
Using these properties, we can see that:- The midpoints of the legs are congruent, since the legs are congruent.
- The midpoints of the bases are congruent, since the bases are congruent.
- The segments joining the midpoints of the legs and the bases are congruent, since they are both the same distance from the midpoint of the bisected diagonal.
Therefore, the segments joining the midpoints of the sides of an isosceles trapezoid are congruent, and since they are congruent they form a rhombus.The slope of ef and gd can be found by using the formula: slope = (y2 - y1) / (x2 - x1) where ef = (x1, y1) and gd = (x2, y2) are the coordinates of the points e and g.
Since the slope of the line perpendicular to the diagonals of a rhombus is always opposite reciprocal, the slope of ef and gd are opposite reciprocal, which means:the slope of ef = -1/slope of gd.

Do sides 10 cm 24cm 26cm from a right angled triangle justify?
The sides 10 cm, 24 cm and 26 cm can form a right-angled triangle. The Pythagorean theorem can be used to verify this.
From Pythagorean theorem, it can be said that, the square of hypotenuse side is equal to the sum of other two sides of a right angled triangle.
Let AB, CA and BC be the sides of a right triangle. CA is the hypotenuse side, AB and BC are the base and height sides of the right triangle. The equation can then be expressed as,
CA² = AB² + BC²
Now, let us check this rule for the above given sides of the triangle.
Longest side² = Sum of squares of other two sides
26² = 24² + 10²
676 = 576 + 100
Thus, the sides 10 cm, 24 cm and 26 cm can form a right-angled triangle.

Answer:
b) m = -2 and b=10 and c) m= 2/5 and b=4
Step-by-step explanation:
For b, we know that the b value (y-intercept) is 10 because it is the y value when x= 0, which is shown on the table as 10.
Next, to find the slope (m-value) we know that 10 gets added to the y value so then x(2) + 10 = 6
subtract 10 from both sides and you get 2x = -4
divide both sides by 2 to get x= -2 or our m-value (slope)
-------------------------------------------------------------------------------------------------------------
For c, we know that the graph intercepts the y-axis at 4, so that is our b value.
We know know: y= m(x) + 4
To find the slope, we use the formula: rise/run
When the graph goes up 6 to get to y=10, the x value goes 15 across
Rise = 6 ; Run = 15
6/15 = 2/5
Therefore, the m value is 2/5
