A 30-sided regular polygon has an angle measure represented as 6g°.Determine the value of g.

Answers

Answer 1

Answer:

Answer:

g=28

Step-by-step explanation:

an interior angle of polygon=( (n-2)*180)/n which n is the amount of side

30-sided regular polygon = ((30-2)*180)/30 = (28*180)/30 = 168

find g:

6g=168

g=168/6

g=28

Factor by using the perfect-square trinomial formula.

100x^2+20x+1

Answers

to factor first multily 100 and 1 and get 100

then find what 2 numbers multiply to get 100 and add to get 20

the numbers are 10 and 10

so
split the center term up
100x^2+10x+10x+1
group
(100x^2+10x)+(10x+1)
undistribute
(10x)(10x+1)+(1)(10x+1)
undistribute/reverse distributive property
(10x+1)(10x+1)
(10x+1)^2

sincethis is a perfect square problem, the answer will be in the form (ax +b) ^ 2. what can you tell from looking at the original equation? x^2does not have a coefficient in front of it, so a = 1. the second term isnegative, so b must be negative. finally, the last number 100 is thesquare of + or - 10, so b must be +10 or -10, but we already figured bhas to be negative, so b = -10

adam drew 2 same size rectangles and divided them into the same number of equal part. he shaded 1/3 od one rectangle and 1/4 of other rectangle. what is the least number of parts into which both rectangles could be divided?

Answers

i would say that he divided each rectangle in 12 identical parts
for the first rectangle he shaded 1/3 of 12 = 4 parts
for the second rectangle he shaded 1/4 of 12= 3 parts

so 12= 3*4 leads to a minimum of 12 parts
:)

Answer:

1/4 of 12. 12 parts

Step-by-step explanation:

For the first rectangle, he shaded 1/3 of 12-- that is 4 parts.

For the second rectangle, he shaded 1/4 of 12-- and that is 3 parts. So, 1/4 of 12 is 3, so the answer is 12 parts.
