how many bricks do we need to build a wall that is 7m long 15 cm wide and 8 m high if each brick ha length 20 cm breadth 10 cm and height 5 cm |
|
Answer» ⇒ Final Answer: 8400 bricks ⇒ Given: Length of wall = 7 m Breadth of wall = 15 cm Height of wall = 8 m Length of brick = 20 cm Breadth of brick = 10 cm Height of brick = 5 cm ⇒ To Find: No. of bricks required to build the wall of given dimensions. ⇒ Analysis: First of all, we NEED to convert all the dimensions of the to cm and then find the volume of the wall. Next, we need to find the volume of one brick and then divide the volume of one brick from the total volume of the wall. ⇒ Formula to be used: ⇒ SOLUTION: First we can find the volume of the wall: Length = 7 m = 700 cm Breadth = 15 cm Height = 8 m = 800 cm Volume of the wall = lbh = 700 X 800 x 15 = 8400000 cm³ Now, the volume of one brick: Length = 20 cm Breadth = 10 cm Height = 5 cm Volume of the brick = lbh = 20 x 10 x 5 = 1000 cm³ No. of bricks required: Hence 8400 bricks are required.

One of the angles of a triangle is of measures 1300, and the other two angles are of the same measures. Find the measure of each of these equal angles. |
|
Answer» Answer: the equal ANGLES are 25 degrees Step-by-step explanation: If one is 130 degrees and other two are equal sum of angles of the triangle is always equal to 180 degrees. let the equal angles be x then, x+x+130=180 2x +130-130= 180-130 (SUBTRACTING both sides with 130) 2x = 50 2x/2 = 50/2 (DIVIDING both sides by 2) x = 25 |

Answer» Answer: Its trapezium bro Step-by-step explanation: Know how black hole works There are two theories:- 1.A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it.[1] The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.[2][3] The boundary of the region from which no escape is POSSIBLE is called the event horizon. Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, according to general relativity it has no locally detectable features.[4] In many ways, a black hole acts like an ideal black body, as it reflects no light.[5][6] Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe directly. Objects whose gravitational FIELDS are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace.[7] The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was first published by David Finkelstein in 1958. Black holes were long considered a mathematical curiosity; it was not until the 1960s that theoretical work showed they were a generic prediction of general relativity. The discovery of neutron stars by Jocelyn Bell Burnell in 1967 sparked interest in gravitationally collapsed compact objects as a possible astrophysical reality. Black holes of stellar mass are expected to form when very massive stars collapse at the end of their life cycle. After a black hole has formed, it can continue to grow by absorbing mass from its surroundings. By absorbing other stars and merging with other black holes, supermassive black holes of millions of solar masses (M☉) may form. There is consensus that supermassive black holes exist in the centers of most galaxies. The presence of a black hole can be inferred through its interaction with other matter and with electromagnetic radiation such as visible light. Matter that falls onto a black hole can form an external accretion disk heated by friction, forming quasars, some of the brightest objects in the universe. Stars passing too close to a supermassive black hole can be shred into streamers that shine very brightly before being "swallowed."[8] If there are other stars orbiting a black hole, their orbits can be used to determine the black hole's mass and location. Such observations can be used to exclude possible alternatives such as neutron stars. In this way, astronomers have identified numerous stellar black hole candidates in binary systems, and established that the radio source known as Sagittarius A*, at the core of the Milky Way galaxy, contains a supermassive black hole of about 4.3 million solar masses. On 11 FEBRUARY 2016, the LIGO Scientific Collaboration and the Virgo collaboration announced the first direct detection of gravitational waves, which also represented the first observation of a black hole merger.[9] As of December 2018, eleven gravitational wave events have been observed that originated from ten merging black holes (along with one binary neutron star merger).[10][11] On 10 April 2019, the first direct image of a black hole and its vicinity was published, following observations made by the Event Horizon Telescope in 2017 of the supermassive black hole in Messier 87's galactic centre 2. White hole is just hypothetical thing.This theory states that what a Black hole eats it comes out of white hole. Einstein-Rosen Bridges are nothing but wormholes. In short, an Einstein-Rosen bridge is a wormhole. The idea was proposed by an Austrian physicist NAMED Ludwig Flamm who envisioned the existence of an anti-black hole. Flamm believed that a theoretical “white hole” COULD exist that, unlike a black hole, would occasionally spit stuff out rather than suck it all in. Mark me as BRAINLIEST |

Which is greater the sum of 4 1/2 and 2 1/5 or the sum of 3 2/3 and 3 1/2By how much is greater? |
|
Answer» Step-by-step explanation: 1,3,5,7→ four digits ∴ number of numbers =4!=24 We have to find the SUM of these 24 numbers suppose 7 is in the UNIT PLACE, then the remaining three can be arranged as 3!=6 ways. Similarly, other digits can occupy the first place in 6 ways. Hence, even due to unit place of all the 24 digits number =6(7+5+3+1) UNITS =96 units. Again suppose 7 is in the second place i.e., tens place and it will be so in 6 numbers. Similarly, each digit will be in tens place of all the 24 numbers. =6(7+5+3+1)tens =96×10 units Proceeding similarly for hundreds and thousands. The sum=96(1+10+100+1000)=96×1111=106656 |

Answer» Step-by-step explanation: Cricket is a bat-and-ball game played between two teams of ELEVEN players on a field at the centre of which is a 22-yard (20-metre) pitch with a wicket at each end, each comprising two bails balanced on three stumps. The batting SIDE scores runs by striking the ball bowled at the wicket with the bat (and running between the wickets), while the bowling and fielding side tries to prevent this (by preventing the ball from LEAVING the field, and getting the ball to either wicket) and dismiss each batter (so they are "out"). Means of dismissal include being bowled, when the ball hits the stumps and dislodges the bails, and by the fielding side either catching the ball after it is hit by the bat and before it hits the ground, or hitting a wicket with the ball before a batter can cross the crease in front of the wicket. When ten batters have been dismissed, the innings ends and the teams swap roles. The game is ADJUDICATED by two umpires, AIDED by a third umpire and match referee in international matches. They communicate with two off-field scorers who record the match's statistical information. Cricket |

|
Answer» Before, finding the answer. LET's find out on how we can find the answer.
_____________________________ Given :
To find :
Solution : Perimeter of Rectangle = (2 × l) + (2 × b) = (2 × 100) + (2 × 300) = 200 + 600 sq.units = 800 sq.m HENCE, the Perimeter of Rectangular Field is 800 sq.m Perimeter of Square = 4 × s = 4 × 15 sq.m = 60 sq.m Hence, the Perimeter of Square is 60 sq.m Difference = 800 - 60 m = 740 m Arun jogs more than Tarun by 740 m. |
