\frac{(n-2)\cdot180}{n}=144\\
180n-360=144n\\
36n=360\\
n=10

It's decagon.

Here is the formula for find the one inside of the polygon: 
(n-2).180/n (n shows how many sides does polygon have)
so now we can solve the equation==== (n-2).180/n=144
1144n=(n-2).180
144n=180n-360
360=36n
n=10 
so we call it decagon :)

M+4+2-7m+6 I need to find how many’s terms are in it and what are the terms
madreJ [45]

Answer:

5 terms:  m, 4, 2, -7m, 6 are the terms in question.

Step-by-step explanation:

Note that terms here are separated from one another by either + or - signs.

m + 4 consists of two terms, since m and 4 are separated by the + operator.

2 - 7m are separated by the - operator, and so there are two terms here.

Completing the counting procedure, we get:

m (first term) + 4 (second term) + 2 (third term -7m (fourth term) + 6 (fifth term).

So, if we do NOT combine like terms, we have five (5) terms altogether.

If we DO combine like terms, we end up with two (2) terms:

m -7m + 4 + 2 + 6, or -6m + 12, or two (2) terms.

Fraction that is less than 5/6 and has a denominator of 8
Evgesh-ka [11]
See 5/6 is obviously more than 1/2 so 4/8 works
also 3/8 or 2/8 or 1/8

if you want all fractions then
5/6=x/8
times 24 both sides
20=3x
divide 3
6 and 2/3=x
basically x/8 such that x<6 and 2/3


examples
6/8
5/8
4/8
3/8
2/8
1/8
I would use the odd ones since the even ones simplify to non-eight denomenators

A study in your town found that 54 in 1,762 people have a post office box what percent of the people in town have a post office
gavmur [86]
Multiply 54 times 100 then divide by 1,762

54 times 100= 5400

5400\1,762= .03

which equals to 3%
