Answer:

The lowest whole number ratio of the elements in a compound is called the empirical formula.

Step-by-step explanation:

A molecular formula consists of the chemical symbols of the constituent elements of a compound followed by numerical subscripts that describe the number of atoms of each element present in the molecule.

Then, the representation of the elements that form a compound and the proportion in which they are found, or the number of atoms that form a molecule is called the chemical formula.

The empirical formula is an expression that represents the simplest proportion in which atoms that form a chemical compound are present. It is then the simplest representation of a compound. Therefore, it is called the minimum formula.

In summary, the empirical formula is a formula that indicates the simplest integer ratio of all atoms in a molecule.

Finally, the lowest whole number ratio of the elements in a compound is called the empirical formula.

If a 45 45 90 triangle has the hypothenuse of 10 what would the legs x and y be

melamori03 [73]

Answer:

Step-by-step explanation:

When working with 45-45-90 triangles the hypotenuse is the same as the other legs multiplied by root 2. Therefore if you need to find the legs and already have the hypotenuse, divide the hypotenuse by root 2.

10/ sqrt(2) = 7.1 is the rounded answer.

to double check your work just multiply 7.1 by the square root of 2 and you'll get close to 10. (because the answer is rounded and not exact.)

Using your own words, explain direct and inverse proportionality. (Be sure to use complete sentences.)

Lerok [7]

The number of pencils is directly proportional to the cost. ... Two values x and y are inversely proportional to each other when their product xy is a constant (always remains the same). This means that whenx increases y will decrease, and vice versa, by an amount such that xyremains the same.

Audryn left a $12 tip on a $68.73 restaurant bill. What percent tip did she leave? Round to the nearest tenth of a percent.

Andrew [12]

Well, if we take 68.73 as the 100%, how much is 12 of it in percentage?

well $\bf \begin{array}{ccllll}
amount&\%\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
68.73&100\\
12&x
\end{array}\implies \cfrac{68.73}{12}=\cfrac{100}{x}$

solve for "x"

Please show your work. Find XY

Sidana [21]

XY = 17.

Because YW is a perpendicular bisector, we can say that TW and WZ are both equal to 3. It tells us that XZ is 12, so that means that XW must be 12+3 which equals 15.

It also tells us that YW is 8. So we can use the Pythagorean Theorem to find the hypotenuse of Triangle XWY. Thus, $15^{2} + 8^{2} = XY^{2}$

To solve this equation, square and add both of the terms on the right like this:
$289 = XY^{2}$

And then take the square root of both sides. Your final answer should be:
XY = 17.
