Can all Quadrilaterals can be inscribed in circles?
Space and AstronomyNot all quadrilaterals can be inscribed in circles and so not all quadrilaterals are cyclic quadrilaterals. A quadrilateral is cyclic if and only if its opposite angles are supplementary. Which quadrilaterals can always be inscribed in a circle? Cyclic QuadrilateralsA cyclic quadrilateral is a quadrilateral that can be inscribed in a circle. Which quadrilaterals Cannot
Is a square Sometimes a rhombus?
Space and AstronomySince rhombuses are quadrilaterals with 4 congruent sides, squares are by definition also rhombuses. 5. A parallelogram is a rectangle. Can a square be a rhombus True or false? A rhombus is a quadrilateral with all sides equal in length. A square is a quadrilateral with all sides equal in length and all interior angles
What is the formula of area of 4 walls?
Space and AstronomyThe area A of four walls of a room of length l, breadth b and height h is given by the formula A=2(l+b)h. What is the formula for area of walls? To calculate the area of a wall, use the standard formula of Length x Width = Area. Next, use the same formula to record
How do you find area in square units?
Space and AstronomyHow do you find the unit area? Area is the amount of surface a two-dimensional shape can cover, measured in square units. The SI unit of area is the square meter (m2), which is a derived unit. Common Units of Area 100 cm2 = 1 square decimeter (dm2) 100 dm2 = 1 square meter (m2)
What asteroid will hit Earth in 2020?

Discovery Semi-major axis 0.9227 AU (138.03 Gm) Eccentricity 0.1914 Orbital period (sidereal) 0.89 yr (323.7 d) Average orbital speed 30.73 km/s Which asteroid is coming towards Earth in 2020? Asteroid 2020 AP1 will come
How do you adjust the moon phase on a watch?
Space and AstronomyHow accurate are moon phase watches? Most of our moon-phase displays are 99.998 per cent accurate, so if the watch runs without interruption, a correction by one day is only needed when 122.6 years have elapsed. This is achieved with an ingenious mechanical transmission that steps down the rotation of the hour wheel. What is
How long ago was the Moon formed?
Space and Astronomy~4.5 billion years ago~4.5 billion years ago, about 30–50 million years after the origin of the Solar System, out of debris thrown into orbit by a massive collision between a smaller proto-Earth and another planetoid, about the size of Mars. When was Moon formed? 4.5 billion years ago It smashed into the developing Earth 4.5

What is George Boole famous for?
Space and AstronomyGeorge Boole, (born November 2, 1815, Lincoln, Lincolnshire, England—died December 8, 1864, Ballintemple, County Cork, Ireland), English mathematician who helped establish modern symbolic logic and whose algebra of logic, now called Boolean algebra, is basic to the design of digital computer circuits. How did George Boole change the world? The real value of Boole’s work
How does distance affect brightness of stars?
Space and AstronomyThe apparent brightness of a star is proportional to 1 divided by its distance squared. That is, if you took a star and moved it twice as far away, it would appear 1/4 as bright; if you moved it four times the distance, it would appear 1/16 as bright. The reason this happens is simple.
