For question 1 and 2, you should keep in mind that the sum of all angles in a triangle is 180°. 1. If the measure of one angle of a triangle is 90 degrees, you can assume that the sum of the other two triangles should be 90 degrees. Because
180 - 90 = 90
The sum of the three angles of any triangle is equal to 180 degrees.
Angle 2=127 because 180-53=127.
Angle 3=23 because 180-30-127=53
Angle 1=37 because 90-53=37
Angle 4=90
Angle 1+4=127
The measure of ∠1 is 125° .
Next x+64=110. The reason why you can do this is because ∠R is going to be an opposite interior angle. Subtract 64 from the left and right sides. x=46

Order the steps for constructing a circle that is circumscribed about a triangle
Answer:
1. Construct the perpendicular bisector of one side of triangle.
2. Construct the perpendicular bisector of another side.
3. Where they cross is the center of the Circumscribed circle.
4. Place compass on the center point, adjust its length to reach any corner of the triangle, and draw your Circumscribed circle!
There are four steps for constructing a circle that is circumscribed about a triangle.
What exactly is the triangle?A triangle is a three-sided polygon with three angles. The total of the triangle's angles is 180 degrees.
The steps for constructing a circle that is circumscribed about a triangle are as follows;
1. Draw the perpendicular bisector of one of the triangle's sides.
2. Create another side's perpendicular bisector.
3. The intersection is the circumscribed circle's center.
4. Place the compass on the center point, change the length of the compass to reach any corner of the triangle, and draw your circumscribed circle.
Hence, the above steps help to construct a circle that is circumscribed about a triangle.

There are 12 students running for three student coun-
cil positions: president, vice president, and secretary.
Which of the following expressions represents the
number of ways in which these three positions can be
filled by the 12 candidates?
(a) 12.12.12
(c) 12.11.10
3.2.1
(b) 12 · 11 · 10
(d) 12!
The solution is Option C.
The number of ways 3 positions can be filled by the 12 students is given by combinations where ¹²C₃ = ( 12 x 11 x 10 ) / 3 x 2 x 1
What are Combinations?
The number of ways of selecting r objects from n unlike objects is:
ⁿCₓ = n! / ( ( n - x )! x! )
where
n = total number of objects
x = number of choosing objects from the set
Given data ,
Let the equation be represented as A
Now , the value of A is
The total number of students n = 12 students
The number of positions in the council x = 3 positions
So , the number of ways the 3 positions can be filled by 12 students is calculated by combinations
where n = 12 and x = 3
ⁿCₓ = n! / ( ( n - x )! x! )
Substituting the values in the equation , we get
¹²C₃ = ( 12! / ( 12 - 3 )! 3! )
On simplifying the equation , we get
¹²C₃ = ( 12! / 9! 3! )
And ,
¹²C₃ = ( 12 x 11 x 10 x 9! / 9! 3! )
¹²C₃ = ( 12 x 11 x 10 ) / 3!
¹²C₃ = ( 12 x 11 x 10 / 3 x 2 x 1 )
¹²C₃ = 220 ways
Hence , the number of ways the 3 positions can be filled by the 12 students is 220 ways

Por enviar un paquete e de 5kg de peso a una ciudad que está a 60km de distancia una empresa de transporte me ha cobrado 9€ cuanto me costará enviar un paquete de 50 kg a 200km de distancia
Responder:
300 €
Explicación paso a paso:
Dado que:
El peso del paquete de 5 kg enviado a una distancia de 60 km es de 9 €
Tomando el producto:
5 * 60 = 9 €
300 kgkm = 9 €
1 kg · km = 9/300 €
= 0,03 €
Para un paquete de 50 kg, enviado a una distancia de 200 km:
50 * 200 = 10000 kgkm

A Ferris wheel has a 44-foot radius and the center of the Ferris wheel is 50 feet above the ground. The Ferris wheel rotates in the CCW direction at a constant angular speed of 3 radians per minute. Josh boards the Ferris wheel at the 3-o'clock position and rides the Ferris wheel for many rotations. Let tt represent the number of minutes since the ride started.
Write an expression (in terms of t) to represent the number of radians Josh has swept out from the 3-o'clock position since the ride started.
How long does it take for Josh to complete one full revolution (rotation)?
________ minutes
Write an expression (in terms of t) to represent Josh's height above the center of the Ferris wheel (in feet).
Write a function f that determine's Josh's height above the ground (in feet) in terms of t.
f(t)=
Answer:
Part A
The expression in terms of 't' representing the number of radians Josh has swept since the ride started is 3·t rad
Part B
The time to complete one revolution is (2·π/3) minutes
Part C.
The function 'f' that determines Josh's height above the ground (in feet) in terms of 't' is, f(t) = 44·sin(3·t + π/2) + 50
Step-by-step explanation:
The radius of the Ferris wheel = 44 foot
The height of the Ferris wheel above the ground = 50 feet
The direction of rotation of the Ferris wheel = CCW
The angular speed of the Ferris wheel, ω = 3 radians per minute
The position from which Josh boards the Ferris wheel = 3-O'Clock
The number of minutes since the ride started started = t
Part A
The expression in terms of 't' to represent the number of radians Josh has swept since the ride started = ω × t = 3 × t rad = 3·t rad
Part B
One complete revolution = 2·π radians
The time to complete one revolution = 2·π/ω = 2·π/(3 rad/minute) = (2·π/3) minutes = [tex]0.\overline{6}[/tex]·π minutes ≈ 2.0943951 minutes
Part C.
The height, 'h', of the Ferris wheel is given by the following sinusoidal relation
f(t) = A·sin(B·t + C) + D
Where;
A = The amplitude = The radius of the Ferris wheel = 44 ft.
The period, T = (2·π/3) minute
B = 2·π/T = 3
t = The time in minutes
D = The Ferris wheel's height above ground = 50 ft.
C = The horizontal shift = π/2 (Josh boards the Ferris wheel at t = 3-O'Clock which is the midline, a rotation of π/2 from the lowermost end of the Ferris wheel)
Therefore the function that determines Josh's height above the ground (in feet) in terms of 't' is presented as follows;
f(t) = 44·sin(3·t + π/2) + 50

Tate purchased a pair of slippers on the internet for a retail price of $16. After 6.5% sales tax, how much were the slippers?
Answer:
$15.02
Step-by-step explanation:
Given data
Total cost= $16
tax= 6.5%
let the actual cost of the slippers be x
6.5/100*x+ x= 16
0.065x+x= 16
1.065x= 16
divide both sides by 1.065
x= 16/1.065
x= 15.02
Hence the actual cost of the slippers is $15.02
