A person buys 140 articles at Rs.2400. He sells33.33% of his articles at 14% profit ,5/7 part of remaining articles he sells at 20% profit. Then at what profit or loss % he should sell remaining articles so that overall he will gain 12% profit? |
|
Answer» 2% PROFIT Explanation: 33.33% or 1/3 of 140 ARTICLES = 46.6 articles Remaining articles = 140 - 46.6 = 93.4 articles 5/7 of remaining articles = (5/7) x 93.4 articles = 66.7 articles Remaining articles = 140 - (46.6 + 66.7) = 26.7 articles Average Profit % = (Profit % of 33.33% articles' SP + Profit % of 5/7 of the remaining articles' SP + Profit % 'x' for remaining 26.7 articles' SP)/3 Average Profit = Given, 12% 1st Profit = 14% 2nd Profit = 20% 3rd Profit = 'x'% Removing PERCENTAGE from all values since all values are alike - 12 = (14 + 20 + x)/3 36 = 14 + 20 + x 36 - (14 + 20) = x 36 - 34 = x x = 2 Hence, answer is 2% for the remaining articles. |

If the entire Antarctic ice melts, about 25 million cubic kilometers of water will bereleased. This will spread out over Earth's 340 million square kilometers of oceansurface. Find the amount that sea level will rise. |
|
Answer» Step-by-step explanation: Ice on land Sea level EQUIVALENT (m) Antarctic Ice Sheet 57.9 Greenland Ice Sheet 7.42 Glaciers and ice caps 0.32 Antarctica The first complexity is in calculating the volume of ice in the world. This is complex, as we often do not have a complete picture of the bed of the ice sheet or glacier. For Antarctica, BEDMAP2 and Bedmachine provides the most complete and up-to-date estimate of ice volume, and it is derived by COMBINING thousands of radar and seismic measurements of ice thickness [2,3]. In fact, BEDMAP 2 is derived from 25 million measurements. Fretwell et al. 2013 estimated that the Antarctic Ice Sheet comprised 27 million km3 of ice, with a sea level equivalent of ~58 m. BedMachine estimates the sea level equivalent of Antarctica to be 57.9 ± 0.9 m [3]. Greenland BedMachine V3 provides a recent estimate of ice volume for the Greenland Ice Sheet [4]. In Greenland, the bed topography is a primary control on ice flow, grounding LINE migration and calving, and subglacial drainage. DEEP fjords allow penetration of warm Atlantic Water that undercuts Greenland’s tidewater glaciers that terminate in the ocean. This means that sectors of the Greeland Ice Sheet, like the Antarctic Ice Sheet, are also vulnerable to oceanic forcing. The BedMachine V3 is a 150 m horizontal resolution bed topography and bathymetric map, which shows that the sea level potential of the Greenland Ice Sheet is 7.42 ± 0.05 m [4]. Global glaciers For glaciers, ice thickness datasets are sparse [5]. While we have a good estimate of global glacier ice surface area [6] from satellite measurements, direct observations of glacier ice thickness are available for only around 3000 glaciers [5, 7, 8; Welty et al.]. These include radar measurements (both airbourne and from the ice surface) and seismic measurements. Unfortunately, these methods are time consuming and costly, and glaciers are often remote and difficult to access. The mass of ice is usually given in metric gigatonnes (Gt). 1 Gt = 109 tonnes (where 1 tonne = 1000 kg); a gigatonne is 1 billion tonnes. A tonne of water occupies one cubic metre (a cube 1m x 1 m x 1m). A gigatonne (Gt) occupies one cubic kilometre of water (1km x 1km x 1km). Densities of ice and water Calculating the sea level equivalent for a given volume of ice requires some simple maths and a KNOWLEDGE of the densities and properties of ice and sea water. Ice volumes are usually given in km3. please make me brainlist Dear and follow me on |

Simplify the following: -7 + 3s - 4Simplify the following: 8(2r - 1) Simplify the following: -(7p - 2) Simplify the following: 12t + 9 - 4x - 1 |
|
Answer» SIMPLIFYING 3p + -4r + 7p + -2r = 0 REORDER the terms: 3p + 7p + -4r + -2r = 0 Combine LIKE terms: 3p + 7p = 10p 10p + -4r + -2r = 0 Combine like terms: -4r + -2r = -6r 10p + -6r = 0 Solving 10p + -6r = 0 Solving for VARIABLE 'p'. Move all terms containing p to the left, all other terms to the right. Add '6r' to each side of the equation. 10p + -6r + 6r = 0 + 6r Combine like terms: -6r + 6r = 0 10p + 0 = 0 + 6r 10p = 0 + 6r Remove the zero: 10p = 6r Divide each side by '10'. p = 0.6r Simplifying p = 0.6r Simplifying -7p + -7p = 0 Combine like terms: -7p + -7p = -14p -14p = 0 Solving -14p = 0 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Divide each side by '-14'. p = 0 Simplifying p = 0 |

Vinay and Versha run a race with their speeds in the ratio of5:3. They prefer to run on a circular track of circumference1.5 km. What is the distance covered by Vinay when hepasses Versha for the seventh time? |
|
Answer» Since, the SPEEDS of Vinay and Versha are in the RATIO 5:3 i.e. when Vinay COVERS 5 rounds, then Versa covers 3 rounds, but first time Vinay and Versha meet when Vinay completes {2(1/2)= 2.5} round and Versha completes 1/2 round. = 26.25 km. |

Question 22.Hasan buys two kinds of cloth materials for school uniforms, shirt material that costs him Rs 50 per metreand trouser material that costs him Rs 90 per metre. For every 2 meters of the trouser material he buys 3 metres of theshirt material. He sells the materials at 12% and 10% profit respectively. His total sale is Rs 36660. How much trousermaterial did hebuy? |
|
Answer» Answer: Hey mate hope it helps you ✍️ Step-by-step explanation: Let material bought for trousers and SHIRTS be 2X meters and 3x meters respectively. Cost PRICE of 2x METRES of trouser material at Rs. 90 per metre =Rs(90×2x)=Rs180x and Cost price of 3x metres of SHIRT material at Rs. 50 per metre =Rs(50×3x)=Rs150x Given, profit in case of shirt material = 12% ∴ Its S.P. =Rs(150× 100 112
)=Rs168x Also, profit in case of trouser material = 10% ∴ Its S.P. =Rs(180× 100 110
)=198x ∴ Total selling price =Rs.(168x+198x) =Rs.366x But the total selling price is given as Rs. 36600. ∴366x=36600⇒x= 3666 36660
=100 Thus, the trouser material purchased =2×100m =200m |

MEDIUM Share Study later ANSWER Given a cylindrical pillar diameter of 56cm and its height is35m. Then radius of pillar = 2 56
CM= 100 28
m=0.28m Then curved surface area of pillar =2πrh=2× 7 22

On a chapter test, Stephanie uses the rules of equation solving and inverse operations to solve the cubic equation below. The directions on the test are not very specific; however, they do say to give an exact solution. Stephanie is not sure if she should submit a decimal approximation or a simplified radical as the answer.4x^3 = 7561. What recommendation can you make to Stephanie regarding her answer to the cubic equation above? In your recommendation, explain what the term "exact" indicates with regards to the solution.2. Solve the cubic equation from Stephanie’s test. Submit two solutions for the equation- a) your answer as a decimal approximation, rounded to the nearest hundredth, and b) as a simplified radical. Use substitution to check each version of your solution in the original equation.3. After solving the test question and checking both the decimal solution and the simplified radical form, would you change your recommendation (in Part 1) to Stephanie regarding the format of her answer? Use complete sentences to explain your reasoning. |
