Answer» ong>Given : Cate solved an inequality to find c, the possible NUMBER of cats that a shelter can house. She found that c < 28 To Find : Which statement best describes a possible SOLUTION to Cate’s problem? The shelter can house 15.6 cats because 15.6 < 28. The shelter can house –8 cats because –8 < 28. The shelter can house 17 cats because 17 < 28. The shelter can house 28 cats because 28 < 28.
Solution: The shelter can house 15.6 cats because 15.6 < 28. cat should be in integers so not a good WAY to represent The shelter can house –8 cats because –8 < 28. Cat can not be negative The shelter can house 17 cats because 17 < 28. Looks fine The shelter can house 28 cats because 28 < 28. 28 is not LESS than 28 hence not possible The shelter can house 17 cats because 17 < 28. statement best describes a possible solution to Cate’s problem Learn More: Write an inequality and show on a number line all numbers: from (–5 ... |

A person buys 140 articles at Rs.2400. He sells 33.33% 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» ong>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 be released. This will spread out over Earth's 340 million square kilometers of ocean surface. Find the amount that sea level will rise. |
|
Answer» ong>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 - 4 Simplify 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 |
