What do aeronautical engineers use ratios and proportions for?
I'm sure they use ratios and proportions at many different points in the practice of their profession. One obvious application is in construction of exact scale models of aircraft and their components for wind-tunnel tests.
When you estimate is your answer exact or approximate?
Estimates are never exact. They are a best guess at what the answer is. They are always going to be approximate.
Do reflections always have a line of symmetry?
Yes and it is always at the exact middle between the shapes
Estimated differences of the weight of two elephants is 100 pounds.give two examples of the exact amounts that would make the estimate reasonable.?
i have a two exact amount or compounds that the same amount and small different. of a two type for example. monkey have a 100 pounds or maybe 80% above. compounds ,last one is karabaw is above 98% compunds. or maybe that exact amount that's small different
What is the exact area of a circle with a diameter of 25 m?
The exact area is 625*pi. Since pi is an irrational number, any exact answer must include pi and may not contain a decimal (or rational) approximation of pi.
What do compounds always contain in exact ratios?
Compounds always contain elements in exact ratios, based on the chemical formula of the compound. This means that the elements are present in specific and consistent proportions in the compound.
Do mixtures contain exact ratios of elements?
No, they do not.
Does 'organic' mean that it contains hydrogen?
Organic compounds are most compounds that contain carbon. There are some carbon compounds, such as carbon dioxide, that are inorganic. Thus, a more specific definition is that an organic compound is a compound that contains carbon bonded to hydrogen, although the exact distinction may not always be this simple.
What the relationship between the elements and the compounds?
Atoms make up all matter. An element has atoms that are all the same. Compounds are made of different kinds of atoms combined chemically in exact whole number ratios.
When do two ratios form a proportion?
When both can multiply its comparisons to when both ratios share the exact same numbers.
What is the relationship between element and compound?
Atoms make up all matter. An element has atoms that are all the same. Compounds are made of different kinds of atoms combined chemically in exact whole number ratios.
What is the difference between stoichiometric and non stoichiometric solids?
Stoichiometric solids have a fixed and constant ratio of elements, while non-stoichiometric solids have variable ratios due to defects in the crystal lattice. Stoichiometric solids follow the laws of definite proportions, whereas non-stoichiometric solids can exhibit a range of compositions within the same material.
What compound does not contain carbon and hydrogen together?
AnswerCompounds that do not contain carbon are inorganic; compounds that contain carbon are organic. Minerals are inorganic compounds.AnswerLoosely speaking, "inorganic".This is not exact scientific terminology, however, because there are inorganic compounds that DO contain carbon. Example: the global warming gas, carbon dioxide (CO2).Answerinorganic compounds.
What are the materials contains components in a fixed ratio?
Compounds contain elements in a fixed ratio. This means that each compound is made up of a specific combination of elements in an exact proportion, such as water (H2O) always having two hydrogen atoms for every one oxygen atom.
What is the relationship between atoms elements and compounds?
I believe...compounds are made up of two or more elements. Elements are made up of atoms.
Why do Greek prefixes appear in the names of ionic or covalent compounds?
Greek prefixes are used in the naming of covalent compounds to indicate the number of atoms of each element present in the compound. These prefixes help in specifying the exact ratio of elements in the compound. In ionic compounds, Greek prefixes are not used because the compounds consist of ions with fixed ratios, so the prefixes are not needed.
How many different compounds are there in crude oil?
Crude oil consists of thousands of different compounds, including hydrocarbons, sulfur, nitrogen, and oxygen compounds. The exact number of compounds in crude oil can vary depending on its source and composition.
