What is the formula for the sum of interior angles of a polygons?
Choices
1. S = 180 (n)
2. S = 180 (n - 2)
3. S = sum of angles/n
What’s the answer???????
Answer:
21x - 28
You would multiply 7 times 3x which is 21 x and then you would multiply 7 times -4 which is -28.
Same as before this test... is just driving me crazy I'm blowing all my points through these so...
Answer and Step-by-step explanation:
For this, you would need to use the trigonometric function Sine and cosine.
The trig equations are:
sin(θ) = [tex]\frac{opposite - side}{hypotenuse}[/tex]
cos(θ) = [tex]\frac{adjacent-side }{hypotenuse}[/tex]
Let's start with Sine:
sin(60) = [tex]\frac{x}{10\sqrt{3} }[/tex]
Multiply both sides of the equation by [tex]10\sqrt{3}[/tex].
[tex]10\sqrt{3} (sin(60)) = x[/tex]
Input into calculator and solve.
x = 15
Now for Cosine:
cos(60) = [tex]\frac{y}{10\sqrt{3} }[/tex]
Multiply both sides of the equation by [tex]10\sqrt{3}[/tex].
[tex]10\sqrt{3} (cos(60)) = x[/tex]
Input into calculator and solve.
y = [tex]5\sqrt{3}[/tex]
x = 15
y = [tex]5\sqrt{3}[/tex]
These are the answers.
I hope this helps!
#teamtrees #PAW (Plant And Water)
Step-by-step explanation:
It's a right triangle with one of the angles being 60°. This means that the leftover angle is 30°. This allows me to use the attached screenshot as a reference, so please check it out if you want to understand how to easily solve those types of equations in the future. Anyway, we can specify the hypotenuse as [tex]a[/tex] .
First, let's calculate the value of [tex]y[/tex].
[tex]a[/tex] = [tex]10\sqrt{3}[/tex]
[tex]y[/tex] = [tex]\frac{a}{2}[/tex]
[tex]y[/tex] = [tex]\frac{10\sqrt{3} }{2}[/tex]
[tex]y[/tex] = [tex]5\sqrt{3}[/tex]
----
Now, let's get to [tex]x[/tex]
[tex]a[/tex] = [tex]10\sqrt{3}[/tex]
[tex]x[/tex] = [tex]\frac{a\sqrt{3} }{2}[/tex]
[tex]x[/tex] = [tex]\frac{10 \sqrt{3} * \sqrt{3}}{2}[/tex]
[tex]x[/tex] = [tex]\frac{10 * 3}{2}[/tex]
[tex]x[/tex] = [tex]\frac{30}{2}[/tex]
[tex]x[/tex] = [tex]15[/tex]
----
[tex]x[/tex] = [tex]15[/tex] and [tex]y[/tex] = [tex]5\sqrt{3}[/tex]

Qual é o comprimento do arco correspondente a um ângulo ao centro de 45 graus, numa circunferência de raio 3 cm ?
Answer:
2.4 m
Step-by-step explanation:
A fórmula para o comprimento do arco é dada como:
Comprimento do arco = 2πr (θ / 360)
Onde r = raio = 3cm
θ = Ângulo em graus = 45 °
Comprimento do arco = 2 × π × 3 (45/360)
Comprimento do arco = 2.356194m
Aproximadamente = 2.4 m

What is the area of the logo?
Answer:
[tex]the \: area \: of \: the \: logo \: is \: {91cm}^{2} [/tex]
Step-by-step explanation:
To determine the area of the logo you have to calculate the area of the triangle and the square that comform it and then add the four areas.
Area of the square.
To calculate the area of the square you have to calculate the square of one of its sides, following the formula:
[tex]a = {a}^{2} [/tex]
Where "a" is the length of one of its side.
The side length of the square is a=7cm, so its area will be:
[tex]asquare = {7}^{2} \\ asquare = {49cm}^{2} [/tex]
Area of the triangles.
The three triangles are equal, they have a base equal to the side of the square, i.e. with a length of 7cm, and their height is h=4cm.
To calculate the area of one triangle, you have to multiply its base by its height and divide by 2, following the formula:
[tex]a = \frac{b.h}{2} \\ a = \frac{7.4}{2} \\ a = \frac{28}{2} \\ a = {14cm}^{2} [/tex]
The area calculated the correspond to one triangle, since all triangles are congruent, you have to multiply the said area by 3 to determine the area of three figures:
[tex]atriangles = 3a \\ atriangles = {42cm}^{2} [/tex]
Now that the area of all shape are calculated, you have to add them to determine the area of the logo:
[tex]alogo = asquare + atriangle \\ alogo = 49 + 42 \\ alogo = {91cm}^{2} [/tex]

A truck travels 333 km in 6 hours. What is the truck’s speed for that trip?
Answer:
55.5 km
Step-by-step explanation:
speed=distance/time
55.5= 333/6
Answer:
55.5 km per hour
Step-by-step explanation:
The simple formula is D_S-T
D is at the top for Distance
S is down to the left for speed
And T to the right as Time
Its simple so just take
Distance: 333km
Time: 6 hrs
333÷5=55.5/1
The following are the ages (years) of 5 people in a room:
17, 21, 15, 15, 25
A person enters the room.
The mean age of the 6 people is now 25.
What is the age of the person who entered the room?
Answer:
57 years
Step-by-step explanation:
total=25*6=150
17+21+15+15+25+x=150
93+x=150
x=150-93
x=57
Answer:
age=57
Step-by-step explanation:
ages=17 21 15 15 25 ?
17+21+15+15+25=93(old mean)
17+21+15+15+25+?=25(new mean)
25(new mean)*6(number of numbers)=150
?=150-93=57
= 57

Answer:
A) 3.44 ft²
Step-by-step explanation:
before cutouts, the area was 4 x 4 = 16 ft²
the circles have a diameter of 2 ft each, and a radius of 1 ft
each circle has an area pf (3.14)(1²) = 3.14 ft²
3.14 x 4 = 12.56 ft²
16 - 12.56 = 3.44 ft² left
Complete the factored form of the algebraic expression
18a + 3 = 3 ( + )
Answer: 0
Step-by-step explanation: 18a + 3 = 3
-3 -3
--------------
18a = 0 you can't divide 18 and zero it would be 0
Answer:
So to factorize an expression, you put it into a form where if you expanded the brackets, you'd get the given expression.. if that makes sense. Therefore, you need to multiply the 3 by something to get 18a, and so the first term is 6a. You don't need to multiply 3 by anything to get 3, so the second term is 1. The final result looks like this :
3(6a + 1)

Which fraction is in reduced form?
4/21
42/54
18/27
2/10
Answer:
4/21
Step-by-step explanation:
4/21 can't be reduced anymore there is no number that goes into 4 and 21 and divides perfectly.
4/21 = 4/21
42/54 = 21/27 = 7/9
18/27 = 6/9 = 2/3
2/10 = 1/5

Solve the inequality.
−3y < −14
Answer:
y<14/3
Step-by-step explanation:
−3y < −14
dividing both side by -3
-3y/-3 <-14/-3
y<14/3
The solution of the inequality will be equal to y<14/3.
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
The given inequality will be solved as,
−3y < −14
Dividing both sides by -3 and solving further.
-3y/-3 <-14/-3
y < 14

Find the area of the figure. Round your answer to the nearest hundredth.
Answer:
28.57 in²
Step-by-step explanation:
the square must be 4 in by 4in so the area = 16in²
the two semicircles are made up of quarter circles with a radius of 2 inches and are equal --> together makes one full circle
area of a circle = [tex]\pi r^{2}[/tex]
r = 2 r² = 4
area of circle = 12.56637061
area of circle + area of square = 28.566
