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
Costo de envío de paquete:
Precio por kgkm = 0,03 €
10000 * 0,03 € = 300 €

5. Find the measure of ∠2. Explain how you found its measure.
Write your answer in the space below.
6. What is the measure of ∠3? Explain.
Write your answer in the space below.
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

AP EX
Step-by-step explanation:
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

A circle with diameter 7 meters
A circle with circumference 24 meters
A circle with circumference 5 pi
Answer:
24 m
Step-by-step explanation:
it is 24metre ok......
The greatest circumference is 25.12 meters.
What is a circle?A circle is a two-dimensional figure with a radius and circumference of 2πr.
The area of a circle is πr².
We have,
A circle with a radius of 4 meters.
Circumference.
= 2πr
= 2 x 3.14 x 4
= 25.12 meters
A circle with a diameter of 7 meters
Radius = 7/2 meters
Circumference.
= 2πr
= 2 x 3.14 x 7/2
= 21.98 meters.
A circle with a circumference of 24 meters
Circumference = 24 meters
A circle with a circumference of 5 pi
Circumference = 5π
= 5 x 3.14
= 15.7 meters
Thus,
The greatest circumference is 25.12 meters.

For a dilation with a scale factor less than 1, how do the angles and side lengths of the preimage relate to the angles and side lengths of the image?
A. Angle are proportional;side lengths are larger
B. Angles are proportional;side lengths are smaller
C. Angles are congruent;side lengths are larger
D. Angles are congruent; side lengths are smaller
The dilation of an image with a scale factor less than 1 will have the angle proportional to the preimage, and the side lengths have been smaller. Thus, option B) is correct.
The dilation factor has been the scale factor that has been used for the enlargement or reduction of the image. The images with a dilation factor of more than 1 enlarge, while the images with a dilation factor less than 1 shrinks.
The angle of the image with a scale factor less than 1 has been proportional as with shrinking, the angles have been reduced proportionally with the scale factor.
The reduction in scale factor from 1 will shrink the image. The shrinked image will be consist of a smaller size. So there has been a reduction in the side length of the image.
So, with the image with dilation of scale factor less than 1, the angles are proportional while the side length is smaller. Thus option B) is correct.

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

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
