Por la comra de un televisor en 130 000 se ha pagado 1/4 al contado y el resto en 6 cuotas en igual valor cada una.
Answer:
Por la compra de un televisor en $ 130000 se ha pagado →1/4 del total al contado → el restante en 6 cuotas de igual valor .
el valor de cada cuota =?
Step-by-step explanation:
Para resolver el ejercicio se procede a realizar la operación indicada de calcular el valor de cada una de las 6 cuotas de igual valor, de la siguiente manera :
1/4 * $130000 = $ 32500
$ 130000 - $ 32500 = 97500 $ 97500 /6 = $ 16250
El valor de cada una de las 6 cuotas restantes es de $ 16250 .

What are Mixed Numbers?A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.
Given data ,
Let the mixed number equation be represented as A
Now , the value of A is
To solve each equation, we can convert mixed numbers to improper fractions, then multiply the fractions, and simplify the result if possible.
A)
A = 5/6 × 4 2/3 = (5/6) × (4×3 + 2)/3
A = (5/6) × 14/3 = 35/9, which is not equal to 3 8/9.
Therefore, equation A is false.
B)
B = 1 1/10 × 8 3/5 = (11/10) × (43/5)
B = 473/50 = 9 23/50, which is not equal to 9 1/2.
Therefore, equation B is false.
C)
C = 3 2/9 × 2 1/6 = (29/9) × (13/6)
C = 377/54 = 6 53/54
Therefore, equation C is true.
D)
D = 2 3/7 × 1 7/8 = (17/7) × (15/8)
D = 255/56 = 4 23/56 = 2 3/8
Therefore, equation D is true.
E)
E = 7/12 × 4 = 7/3 = 2 1/3
Therefore, equation E is true.
Hence , the equations that are true are C, D, and E

Mark buys Apple stock for $100 and its value increases by a factor of 1.5 each week. Which equation represents the relationship between the number of weeks past since purchase, t, and the current value of the stock, V?
Given:
Initial value of the stock = $100
Growth factor = 1.5 each week.
To find:
The equation that represents the relationship between the number of weeks past since purchase and the current value of the stock.
Solution:
Let V be the current value of the stock after t week.
The exponential growth model is:
[tex]V=ab^t[/tex]
Where, a is the initial value of stock, b is the weekly growth factor, t is the number of weeks.
Substituting [tex]a=100,b=1.5[/tex], we get
[tex]V=100(1.5)^t[/tex]
Therefore, the required equation for the given situation is [tex]V=100(1.5)^t[/tex].

PQ and QR are 2 sides of a regular 12-sided polygon.
PR is a diagonal of the polygon.
Work out the size of angle PRQ.
You must show your working.
The size of the angle m∠PRQ for the polygon is equal to 15°
How to calculate for the angle PQR using interior angle of the polygonTo calculate the sum of interior angles of a polygon, you can use the following formula:
Sum of interior angles = (n-2) x 180 degrees
Where "n" represents the number of sides (or vertices) of the polygon.
Given the 12 sided polygon;
(12 - 2) × 180 = 1800
one interior angle = 1800/12 = 150°
The angle PQR is a base angle of the Isosceles triangle ∆PQR with one interior angle of the 12-sided polygon so;
m∠PRQ = (180 - 150)/2
m∠PRQ = 15°.
Therefore, the size of the angle m∠PRQ for the polygon is equal to 15°

The formula to find the number of chairs in each row is m = . If 60 people attend the meeting and each row has 4 chairs, there are rows.
Answer:
m = x / n
n = 15
Step-by-step explanation:
Number of chairs per row = m
Number of rows = n
Number of people = x
Number of chairs per row, m = number of people, x / Number of rows, n
m = x / n
If number of attendees, x = 60 ;
Number of chairs per row, m = 4
The number of rows, n = number of attendees / number of chairs per row, m
Hence, n = 60 / 4 = 15 rows

b Pete won the first heat in 13 minutes 39 seconds. Jacob won the second heat in 14 minutes 16 seconds. Who ran faster? By how much? t
In accordance with the research problem we were given, Pete outran Jacob by 37 seconds.
A second of angle is what?Minutes are the 60 equal pieces that make up each degree. Thus, 7 to 8 inches can also be written as seven degrees and thirty minutes, or seven°30'. For example, 2 ° 5 minutes and 30 seconds are represented by the notation 2° 5' 30 since each minutes is further subdivided into 60 equal seconds.
Then, we have Pete's time: First, we convert minutes into seconds. 13 minutes and 39 seconds is equal to 13 * 60 + 39, or 819 seconds.
Jacob's period: 14 minutes and 16 sec. = 14 * 60 + 16 sec. = 856 sec.
Jacob outpaced Pete by 856 – 819 = 37 seconds.
Pete ran 37 seconds faster as a result.

nearest tenth.
5 cm
13 cm
Surface Area = [? ] cm2 Surface Area = 236 cm2
Answer:
[tex]A=141.6\ cm^2[/tex]
Step-by-step explanation:
The surface area of a cylinder is given by :
[tex]A=2\pi rh[/tex]
For larger cylinder, A = 236 cm² and h = 5 cm
So,
[tex]236=2\pi \times 5\times r\\\\r=\dfrac{236}{10\pi}\\\\r=7.51\ cm[/tex]
Now, Put r = 7.51 and h = 3 cm to find the surface area of the smaller cylinder.
[tex]A=2\pi \times 7.51\times 3\\\\A=141.56\ cm^2\\\\A=141.6\ cm^2[/tex]
So, the surface area of the smaller cylinder is equal to [tex]141.6\ cm^2[/tex].

number 29 and 30 pleasseeeee
Answer:
29 = 16.4
30=
Step-by-step explanation:
The formula for finding a hypotenuse is a^2 + b^2 = c^2. Therefore, if you want to solve 29 you would do 13^2 + 10^2 = c^2.
13^2= 169
10^2=100
269+100 = c^2
368= c^2
So next, we have to do the square root of 368 which is 16.4.
Now for number 30, we know that it is a right triangle. So if we want to work with that, we have to find the angles of everything. We know that the sum of all angles in a triangle is 180. So a right angle is 90 degrees. We have 90 left over. Could you solve the rest?

Write the exact value of the side length of each square. If the value is not a whole number, estimate the length.
area exact side length estimite side length
100 square units ------ units
95 square units bettween ----- and -----
36 square units -------units
30 square units bettween ----- and -----
Given:
The area of the squares are given.
To find:
The exact side length or estimate side length of the square.
Solution:
We know that, the area of a square is
[tex]A=a^2[/tex]
Where, a is the side length of the square.
[tex]a=\sqrt{A}[/tex]
Area of the square is 100 square units. So, the side length is:
[tex]a=\sqrt{100}[/tex]
[tex]a=10[/tex]
Therefore, the side length is 10 units.
Area of the square is 95 square units. So, the side length is:
[tex]a=\sqrt{95}[/tex]
It is not exact. We know that [tex]\sqrt{81}<\sqrt{95}<\sqrt{100}[/tex].
Therefore, the side length is between 9 and 10.
Area of the square is 36 square units. So, the side length is:
[tex]a=\sqrt{36}[/tex]
[tex]a=6[/tex]
Therefore, the side length is 6 units.
Area of the square is 30 square units. So, the side length is:
[tex]a=\sqrt{30}[/tex]
It is not exact. We know that [tex]\sqrt{25}<\sqrt{30}<\sqrt{36}[/tex].
Therefore, the side length is between 5 and 6.
