Answer:

  • triangle
  • square
  • hexagon
  • dodecagon

Step-by-step explanation:

The 12 points marked can be divided into this many equal-size groups:

  3, 4, 6, 12

so the figures that can be constructed are ...

  • triangle . . . . connects every 4th mark
  • square . . . . . connects every 3rd mark
  • hexagon . . . .connects every other mark
  • dodecagon . . connects every mark

_____

12 is also divisible by 1 and 2, but the minimum number of vertices in a regular polygon is 3.

Two sides and an angle​ (SSA) of a triangle are given. Determine whether the given measurements produce one​ triangle, two​ tria
Nataliya [291]
<h2>These measurements will not form a triangle.</h2>

Step-by-step explanation:

We have sine formula

          \frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}

Given

        a = 9.7

        b = 49

        A = 26°

Substituting

        \frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}\\\\\frac{9.7}{sin26}=\frac{49}{sinB}\\\\sinB=2.21

Value of sin B is greater than 1, which is not possible.

Hence these measurements will not form a triangle.

How do I find the n in A=P(1+(r/n)^(nt)?
dmitriy555 [2]
This is the formula for compounded interest.
P is the principal investment,
r is the rate (6%=0.06)
n is the number of times compounded per year (n=12 is monthly, n=2 is twice per year)
T is the number of years past
And A is the amount of money after t years with a rate r compounded n times per year staring at P amount
Final answer:
n is the number of times per year the interest is compounded.
Hope I helped, and sorry it took this long for you to get an answer.

IF ONE THIRD OF THE SCHOOL STUDENTS LIKE MATHEMATICS AND 400 STUDENTS DO NOT LIKE MATHEMATICS , THEN HOW MANY STUDENTS DOES THE
boyakko [2]

Answer:

There are 600 students in this school.

Step-by-step explanation:

Let p represent the total population of the school.

Then (1/3)p represents the number of students who like math.  Subtracting this (1/3)p from p gives an expression representing those who do not like math:  

p - (1/3)p = (2/3)p

400 students do not like math, so (2/3)p = 400.

Solve this for p by multiplying both sides by (3/2):

(3/2)(2/3)p = (3/2)(400), which simplifies to p = 600.

There are 600 students in this school.

A TV that usually sells for $183.26 is on sale for 25% off. If sales tax on the TV is 9%, what is the price of the TV, including
Hatshy [7]
183.26 times .25 = 45.815
183.26 minus 45.815 = 137.445
137.445 times 0.09 = 12.37005
137.445 plus 12.37005 = 149.81505
Which =149.82 rounded
