how do you know what formulas to use when solving for two unknowns

Problem: how do you know what formulas to use when solving for two unknowns I am trying to solve a word problem and still have two unknowns and don't know where to go from there. the problem states: A 10kg object on a 26 degree inclined plane. What are the objects weight and the normal force exerted on the object by the inclined plane? I don't understand what I'm missing. :( An object sitting on a flat surface exerts force straight down, vertical. An object on an inclined plane exerts force in both a vertical and a horizontal direction. You multiply the weight by the cosine of the angle to determine the vertical force, and multiply the weight by the sine of the angle to determine the horizontal force.

solve word problem using polynomials

Problem: solve word problem using polynomials Joe has a collection of nickles and dimes worth $2.15 If the number of dimes was doubled and the number of nickles was increased by 28, the value of the coins would be $4.65. How many nickles and dimes does he have? Let's say he has n nickles and d dimes. 0.05n + 0.10d = 2.15 The problem proposes to increase d to 2d and increase n to n + 28. 0.05(n + 28) + 0.10(2d) = 4.65 We have two equation to work with. Let's multiply both equations by 100 to eliminate the decimals. 100(0.05n + 0.10d) = 2.15 * 100 5n + 10d = 215 100(0.05(n + 28) + 0.10(2d)) = 4.65 * 100 5(n + 28) + 10(2d) = 465 We need to expand this second equation. 5(n + 28) + 10(2d) = 465 5n + 140 + 20d = 465 5n + 140 + 20d - 140 = 465 - 140 5n + 20d = 325 Here's what we have: 1) 5n + 10d = 215 2) 5n + 20d = 325 We can immediately eliminate the n by subtracting equatioin 1 from equation 2.    5n + 20d = 325 -(5n + 10d = 215) ------------------------           10d = 110 10d = 110 10d/10 = 110/10 d = 11 This tells us that Joe currently has 11 dimes. Let's use equation 1 directly above to solve for n. 5n + 10d = 215 5n + 10(11) = 215 5n + 110 = 215 5n + 110 - 110 = 215 - 110 5n = 105 5n/5 = 105/5 n = 21 This one tells us that Joe currently has 21 nickels. We need to check the two numbers against what the problem originally stated. 0.05n + 0.10d = 2.15 0.05(21) + 0.10(11) = 2.15 1.05 + 1.10 = 2.15 2.15 = 2.15 Verified! Answer: Joe has 21 nickels and 11 dimes.

Coin word problem help please

Coin word problem help please There is $68.50. It is made up of 440 US coins. There are three types of coins. What are the coins? I will accept the premise that whoever created this problem believed that there is only one set of coins, and the combinations of those coins, that satisfy the stated requirements. It falls to me to prove that assumption false. There are five U.S. coins in circulation; the half-dollar (H), the quarter (Q), the dime (D), the nickel (N) and the penny (P). Taking any three of them, in certain combinations, we can have 440 coins that add up to $68.50 as I will show. I will begin each list with the three letters repesenting the coins, as inidcated above. The largest coin is listed first, the mid-value coin second, and the smallest coin last. For each group, I will give the first combination and the last combination. Then, I will give the increments/decrements for each of the coins in order to progress to the next combination that satisfies the problem requirements. HQD There are 20 combinations.  1) 2/158/280 20) 59/6/375 To move to the next combination, H increases by 3, Q decreases by 8, D increases by 5. HQN There are 25 combinations.  1) 6/219/215 25) 102/3/335 For each step, H increases by 4, Q decreases by 9, N increases by 5. HQP There are 5 combinations.  1) 26/214/200  5) 122/18/300 For each step, H increases by 24, Q decreases by 49, P increases by 25. HDN There are 42 combinations.  1) 62/372/6 42) 103/3/334 For each step, H increases by 1, D decreases by 9, N increases by 8. HDP There are 7 combinations.  1) 68/342/30  7) 122/48/270 For each step, H increases by 9, D decreases by 49, P increases by 40. HNP There are 7 combinations.  1) 106/304/30  7) 130/10/300 For each step, H increases by 4, N decreases by 49, P increases by 45. QDN There are 69 combinations.  1) 164/274/2 69) 232/2/206 For each step, Q increases by 1, D decreases by 4, N increases by 3. QDP and QNP have no combinations that equal $68.50, and for DNP there are no combinations that even reach $44.00. As you can see, all five types of coins can be used, in the appropriate combinations, to have 440 coins add up to $68.50, making the question, "What are the coins?" unanswerable, or at least, not unique.

Discuss at least three applications of graph theory in the field of computer sciences?

Graphs are among the most ubiquitous models of both natural and human-made structures. They can be used to model many types of relations and process dynamics in physical, biological[1] and social systems. Many problems of practical interest can be represented by graphs. In computer science, graphs are used to represent networks of communication, data organization, computational devices, the flow of computation, etc. One practical example: The link structure of a website could be represented by a directed graph. The vertices are the web pages available at the website and a directed edge from page A to page B exists if and only if A contains a link to B. A similar approach can be taken to problems in travel, biology, computer chip design, and many other fields. The development of algorithms to handle graphs is therefore of major interest in computer science. There, the transformation of graphs is often formalized and represented by graph rewrite systems. They are either directly used or properties of the rewrite systems (e.g. confluence) are studied. Complementary to graph transformation systems focussing on rule-based in-memory manipulation of graphs are graph databases geared towards transaction-safe, persistent storing and querying of graph-structured data. Graph-theoretic methods, in various forms, have proven particularly useful in linguistics, since natural language often lends itself well to discrete structure. Traditionally, syntax and compositional semantics follow tree-based structures, whose expressive power lies in the Principle of Compositionality, modeled in a hierarchical graph. More contemporary approaches such as Head-driven phrase structure grammar (HPSG) model syntactic constructions via the unification of typed feature structures, which are directed acyclic graphs. Within lexical semantics, especially as applied to computers, modeling word meaning is easier when a given word is understood in terms of related words; semantic networks are therefore important in computational linguistics. Still other methods in phonology (e.g. Optimality Theory, which uses lattice graphs) and morphology (e.g. finite-state morphology, using finite-state transducers) are common in the analysis of language as a graph. Indeed, the usefulness of this area of mathematics to linguistics has borne organizations such as TextGraphs, as well as various 'Net' projects, such as WordNet, VerbNet, and others. Graph theory is also used to study molecules in chemistry and physics. In condensed matter physics, the three dimensional structure of complicated simulated atomic structures can be studied quantitatively by gathering statistics on graph-theoretic properties related to the topology of the atoms. For example, Franzblau's shortest-path (SP) rings. In chemistry a graph makes a natural model for a molecule, where vertices represent atoms and edges bonds. This approach is especially used in computer processing of molecular structures, ranging from chemical editors to database searching. In statistical physics, graphs can represent local connections between interacting parts of a system, as well as the dynamics of a physical process on such systems. Graph theory is also widely used in sociology as a way, for example, to measure actors' prestige or to explore diffusion mechanisms, notably through the use of social network analysis software. Under the umbrella of Social Network graphs there are many different types of graphs: Starting with the Acquaintanceship and Friendship Graphs, these graphs are useful for representing whether n people know each other. next there is the influence graph. This graph is used to model whether certain people can influence the behavior of others. Finally there's a collaboration graph which models whether two people work together in a particular way. The measure of an actors' prestige mentioned above is an example of this, other popular examples include the Erdős number and Six Degrees Of Separation Likewise, graph theory is useful in biology and conservation efforts where a vertex can represent regions where certain species exist (or habitats) and the edges represent migration paths, or movement between the regions. This information is important when looking at breeding patterns or tracking the spread of disease, parasites or how changes to the movement can affect other species. In mathematics, graphs are useful in geometry and certain parts of topology, e.g. Knot Theory. Algebraic graph theory has close links with group theory. A graph structure can be extended by assigning a weight to each edge of the graph. Graphs with weights, or weighted graphs, are used to represent structures in which pairwise connections have some numerical values. For example if a graph represents a road network, the weights could represent the length of each road. A digraph with weighted edges in the context of graph theory is called a network. Network analysis have many practical applications, for example, to model and analyze traffic networks. Applications of network analysis split broadly into three categories: First, analysis to determine structural properties of a network, such as the distribution of vertex degrees and the diameter of the graph. A vast number of graph measures exist, and the production of useful ones for various domains remains an active area of research. Second, analysis to find a measurable quantity within the network, for example, for a transportation network, the level of vehicular flow within any portion of it. Third, analysis of dynamical properties of networks.

i need to know how to figure out word problems dealing with solving mph and minutes

i need to know how to figure out word problems dealing with solving mph and minutes the question is 50mph between two towns and they arrived in 25 minutes. im not looking for an answer just the formula to solve so i can study it   (mph) is a mile per hour → this a velocity (speed) so if talking about two towns mean that there will be distance to travel in mile(s). 25 min is the time that used to travel this two town.   as you are going to examen the velocity (mph or mile / hour) this mean Velocity = mile(distance) / hour (Time)   If you will be asked for Distance then Distance = Velocity x Time   If you are asked for time then Time = Distance / Velocity     This is whar you are going to need in solving problem like this.   Remember that Jesus loves you.  Know Him in the Bible God Bless
