In a Chemical formula, Subscript figures tell us how numerous of the element to their upper-left there are in the patch.
What is a chemical formula?
- In chemistry, a chemical formula is a way of presenting information about the chemical proportions of titles that constitute a particular chemical emulsion or patch, using chemical element symbols, figures, and occasionally also other symbols, similar as hiatuses, dashes, classes, commas, and plus() and disadvantage( −) signs.
- These are limited to a single typographic line of symbols, which may include subscripts and subtitles.
- A chemical formula may indicate certain simple chemical structures, it isn't the same as a full chemical structural formula.
The subscript number indicates the total number of titles of an element present in a patch.
While witting a chemical formula, first we've to write the symbol of an element and also write the number at the bottom of the symbol.
For illustration,
is the chemical formula of the glucose patch. The glucose patch is made up of six carbon titles, twelve hydrogen titles, and 6 oxygen titles.
The number 6 of the carbon snippet is written after and at the bottom ( lower- right) of the symbol of carbon element (C). also, the number 12 is written lower-right of the symbol of hydrogen element (H), and the number 6 is written lower-right of the symbol of oxygen element( O).
thus, the subscript figures tell us how numerous of the element to their upper-left there are in the patch.

Answer: 80$
Step-by-step explanation:
Step-by-step explanation:
We have been given that David, Egil and Frances share money in the ratio 2:7:9.
Let 2x, 7x and 9x be the amounts of money that David, Agil and Frances get respectively.
We are told that Frances gets $80 more than David. So we can write this information in an equation as:
9x=2x+80
Now let us solve for x.
9x-2x=80
7x=80
x=\frac{80}{7}
Now let us substitute x=\frac{80}{7} in 7x (amount of money that Egil gets).
\text{ Amount of money that Egil will get}=7\cdot \frac{80}{7}
Upon cancelling out 7 from numerator and denominator we will get,
\text{ Amount of money that Egil will get}=80
Therefore, Egil will get $80.
1. 1/3 - 7/8
rewrite the complex fraction as a division expression
show the complex fraction in simplest form.
step 1
we have

Multiply the first term by 8/8
so
(1/3)*(8/8)=8/24
Multiply the second term by 3/3
(7/8)*(3/3)=21/24
step 2
substitute in the original expression
8/24 -21/24
the fractions have the same denominator
so
(8-21)/24
-13/24
therefore
the answer is
-13/24
Answer:
The Mean 14.5 and the Median is 15
Step-by-step explanation:
For the Mean you just add all the numbers up and divide on how many you have. And the Median the middle
