Answer:
42
Step-by-step explanation:
A regular polygon with 42 sides where the length of each side is 2 units. The units may either be inches or cm or km or miles: any unit of length.
You are given a Regular Polygon with 42 sides. What are the interior angles and exterior angles?
If the length of each side is 2 units, what is the perimeter, area, circum-radius and in-radius of the polygon?
n = 42
Perimeter of a polygon with 42 sides = (side length) x 42 = 84 units
Area of a polygon with 42 sides = (n x Side2 x cot (Π/n))/4 = (n x 22 x cot (Π/42))/4 = 560.45 square units
Sum of the interior angles of a polygon with 42 sides = (n-2) x 180 degrees = (42-2) x 180 degrees = 7200 degrees
Interior Angle of a polygon with 42 sides = (n-2) x 180/n degrees = (42-2) x 180/42 degrees = 171.42 degrees
Exterior angle of a polygon with 42 sides = 180 - Interior Angle = 180 - 171.42 = 8.57 degrees
Inradius = Radius of In-circle = (side length) x cot (Π/42) = 2 x cot 4 = 26.68 units
Circumradius = Radius of Circum-circle = (side length) x cosec (Π/42) = 2 x cosec 4 degrees = 26.76 units
Symmetry Group = D42 42 rotational symmetries and 42 reflection symmetries. The "D" stands for di-hedral.
Find the area of the image
Answer:
I think the answer is 4/3
Step-by-step explanation:
I just substitute
Area =length x width
Area=3X^2-4X(4X^2+5X)
12X^4+15X^3-16X^3-20X^2
12X^4-X^3-20X^2
X^2(12X^2-X-20)

Choose Yes or No to tell whether the symbol will be reversed when the variable is isolated in each inequality.
–10.5 < 3a
b/6 ≤ 7
–4.5c > 9
–21/5 ≤ –5/2d
Please I need this answer right away!!!
Answer:
No, no, yes, yesStep-by-step explanation:
–10.5 < 3a ⇒ -3.5 < a ⇒ a > -3.5
no as variable has positive coefficientb/6 ≤ 7 ⇒ b ≤ 42
no as variable has positive coefficient–4.5c > 9 ⇒ c < - 2
yes as variable has negative coefficient–21/5 ≤ –5/2d ⇒ (-21/5)*(-2/5) ≥ d ⇒ d ≤ 42/25
yes as variable has negative coefficientSolve: 6 divided by 1/6

Answer:
y=27
Step-by-step explanation:
Hello There!
The shown angles are alternate exterior angles
Alternate exterior angles are congruent so
3y+53=7y-55
step 1 add 55 to each side
-55+55 cancels out
53+55=108
now we have
3y+108=7y
step 2 subtract 3y from each side
7y-3y=4y
now we have
4y=108
step 3 divide each side by 4
4/4y=y
108/4=27
we're left with y = 27
Answer:
y = 27
Step-by-step explanation:
The two lines cut by a transversal are parallel, so alternate exterior angles are congruent.
7y - 55 = 3y + 53
4y = 108
y = 27
55 x 32 / 32
HELPPP GIVING BRAINLIEST
Answer:
55
Step-by-step explanation:
Just multiply then divide:
55 x 32 = 1760
1760 ÷ 32 = 55
Or just easier like:
55 x 32 ÷ 32 = 55
Hopefully this helps :3 Sorry if wrong :( Plz mark brainiest if correct :D Your bootiful/handsome! Have a great day luv <3

Gabriela walked to school on 16 of the 24 school days in March. Which value is equivalent to the fraction of the school days in March that Gabriela walked to school? If you do have the answer please put it in with the question so I can see it thank you so much
Answer:
[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
A fraction is a quantity that is not a whole number. In maths, a fraction usually has a numerator and a denominator.
The numerator is the number above. While the denominator is the number below
an example of a fraction = [tex]\frac{4}{5}[/tex]
4 is the numerator while 5 is the denominator
In this question, the numerator would be the number of times she walked to school in march(16). While the denominator would be the number of school days in March
[tex]\frac{16}{24}[/tex]
the above fraction is not in its simplest form. To express in its simplest form, divide both numerator and the denominator by 8 . this gives
[tex]\frac{2}{3}[/tex]

Make t the subject of the formula.
Please help.
Answer:
[tex]t = \frac{2-3q}{q+4}[/tex]
Step-by-step explanation:
[tex]q = \frac{2-4t}{t+3}\\\\[/tex]
Cross multiply,
q(t+3) = 2 - 4t
Use distributive property: a*(b + c) =(a*b) + (a*c)
qt + 3q = 2- 4t
qt + 4t + 3q = 2
qt + 4t = 2 - 3q
t(q + 4) = 2 -3q
[tex]t = \frac{2-3q}{q+4}[/tex]
Matt wanted to buy a new mountain bike. The bike he wants to buy costs $319. He received $85 for his birthday and earned another $147 from his job as an Uber driver. How much more money will he need in order to buy the mountain bike?
Answer:
he will need $87 more to buy a mountain bike.
Step-by-step explanation:
85+147= 232 dollars that he has all together.
subtract that from the total cost of the bike (319-233= $87 more to buy a bike.)

Find the side length of a square with
area 16/49 square inches.
The side length of this square is equal to [tex]\frac{4}{7}\;inches[/tex]
Given the following data:
Area of a square = [tex]\frac{16}{49}[/tex] square inches.To determine the side length of this square:
In this exercise, you're required to solve for the length of the sides of a square that has an area of [tex]\frac{16}{49}[/tex] square inches.
Formula for the area of a square.Mathematically, the area of a square is calculated by using the formula;
[tex]A=S^2[/tex]
Where;
S is the length of each sides of a square.Substituting the value into the formula, we have;
[tex]\frac{16}{49}=S^2[/tex]
Taking the square root of both sides, we have;
[tex]S=\sqrt{\frac{16}{49}} \\\\S=\frac{4}{7}\;inches[/tex]

4/5x+5=9 solve for x please i have 8 questions left!!!!!!!!!!!
Answer:
x= 5
Step-by-step explanation:
You need to get rid of the fraction first and to do that you muliply the whole equation by 5 so that your new equation reads 4x+25=45. Then you subtract 25 from both sides so you have 4x=20. Divide both sides by 4 so x=5.

The perimeter of an equilateral triangle is 6x - 24. Which expression represents the length of one side?
Answer:
side = 2x - 8
Step-by-step explanation:
An equilateral triangle has 3 equal sides.
The perimeter is 3 times one side
In this case P = 6x - 24
Side = p/3 = (6x - 24)/3
Side = 2x - 8
A school has 300 students.If the ratio of boys to girls is 31 to 44, how many more girls are there in the school?
Answer:
there would be 52 more girls I think
Step-by-step explanation:
let x = multiplier then
31x =number of boys
44x = number of girls
Boys + girls = 300
44x + 31x =300
75x = 300
x = 300/75
x = 4 is the multiplier
therefore:
44*4 = 176 girls
31*4 = 124 boys
dif = 52 more girls than boys

explain how rain gauge measures the amount of rainfall
Answer: A rain gauge measures the amount of rainfall based off of the amount collected in the cylinder.
Step-by-step explanation: A rain gauge is really just a cylinder that catches rain. If an inch collects in the cylinder, it means an inch of rain has fallen. It's that simple. Most standard rain gauges have a wide funnel leading into the cylinder and are calibrated so that one-tenth of an inch of rain measures one inch when it collects inside.
