If a boat traveled 6n^2 + 4n miles at an average speed of 2n miles per hour, how long did it take the boat to travel the given distance?
Answers
Answer: 3n+2 hours
To get this answer, you divide the distance over speed
This is because
distance = rate*time
time = distance/rate
So we have
time = (distance)/(rate)
time = (6n^2+4n)/(2n)
time = (6n^2)/(2n) + (4n)/(2n)
time = 3n + 2 hours

Ans : Pentagon has 5 sides.

The pentagon is 15, when octagon is 24.
What is Polygon?
A polygon is a figure made up of line segments (not curves) in a two-dimensional plane. Polygon is the combination of two words, i.e. poly (means many) and gon (means sides).
Polygon with 8 sides known as Octagon and polygon with 5 sides known as Pentagon.
Here, given that, Octagon = 8 sides = 24
So, 1 side= 3
Then, we get, pentagon = 5 sides = (5×3) = 15
Hence, the pentagon is 15.

the upper bound of the area of the circle is qπ cm².

Answer:
The area of the circle is exactly π times the square of its radius. If you are given that the radius is within 0.1cm of 8.5cm, i.e. lies between 8.4 cm and 8.6 cm, its square will lie between p=8.4² = 70.56 and q=8.6² = 73.96 cm².

Ten years ago. Phukan is 18 years younger than Namwan.Currently, the sum of their ages is 100 years. Find their current ages.
WRITE AS AN EQUATION
Answers
Step-by-step explanation:
phukan = x
Nanwan = y
let this be a simultaneous equation.
x - y = 18.... equation i
x + y = 100.... equation ii
subtract equation i from equation ii
= 2y = 118
y = 59
substitute y = 59 in equation ii to get x
x + 59 = 100
x = 100- 59
x = 41
Nanwan = 59, Phukan = 41
Answer:
Nawman = 59 years
Phukan = 41 years
Step-by-step explanation:
P = N - 18
P + N = 100
(N - 18) + N = 100
2N = 100 + 18
2N = 118
N = 118 : 2
N = 59 years
P = (59 - 18) years
P = 41 years

Answers
Answer:
Pregunta 1: Opcion D. 8
Pregunta 2: Opción A. 19 (aunque lo correcto es decir que son 20)
Pregunta 3: 28 años (no está como opción)
Pregunta 4: Opción D. 1/3
Step-by-step explanation:
Las fracciones irreductibles son aquellas que después de dividirlas por un común divisor, una vez que no se pueden dividir más se dice que son irreducibles, por lo tanto no existe ningún número que sea divisor común del numerador y del denominador más que 1.
Fracciones irreductibles con común denominador 24.
Como máximo divisor tenemos el 24 y como mínimo el 1
entre 1/24 y 1 estarán nuestras fracciones o sea:
1/24 < x/24 < 1. Ahora convertimos el 1 en fracción de 24, lo que sería 24/24 para igualar el numerador en ambos lados de la ecuación, para poder determinar x
1/24 < x/24 < 24/24
Como vemos que x tiene que estar entre 1 y 24, las respuestas serán:
2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22 y 23
Eliminamos los números divisores de 24, aquellos pares, y nos focalizamos en los que no podriamos dividir por nada con 24, o sea los números primos
5, 7, 11, 13, 17, 19, 23. Como nos falta el 1, obtenemos un total de 8 fracciones: 1/24, 5/24, 7/24, 11/24, 13/24, 17/24, 19/24, 23/24
Mismo procedimiento para el 25:
1/25 es una de las fracciones irreductibles. Pensamos en los valores de x
1/25 < x/25 < 25/25
2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25
Los números divisibles por 25, son los multiplos de 5, asi que esas respuestas no irían. Las fracciones irreductibles son:
1/25, 2/25, 3/25, 4/25, 6/25, 7/25, 8/25, 9/25, 11/25, 12/25, 13/25, 14/25, 16/25, 17/25, 18/25, 19/25, 21/25, 22/25, 23/25 y 24/25 haciendo un total de
20. Por alguna razón está mal formulada la pregunta, son 20 pero no está como opción y como te piden fraccion impropia (numerador > denominador), contamos a partir de 26. FIjate que hasta el proximo entero que sería 50/25, también son 20 fracciones (irreductibles e impropias)
26/25, 27/25, 28/25, 29/25, 31/25, 32/25, 33/25, 34/25, 36/25, 37/25, 38/25, 39/25, 41/25, 42/25, 43/25, 44/25, 46/25, 47/25, 48/25, 49/25
Próxima pregunta:
Miguel tiene 4/5 de la edad de la novia, y ambas edades suman 63.
Plantiemos la siguiente ecuacion donde x es la edad de la novia
4/5x + x = 63
9/5x = 63
x = 63 . 5/9 (como 9/5 pasa al otro lado de la igualdad dividiendo, damos vuelta la fraccion multiplicandola)
x = 35
Si la novia tiene 35 años y la edad de Miguel es 4/5 de esa edad
4/5 .35 = (35 .4) /5 = 28
Es raro porque no está la respuesta como tal.

Which of the following is NOT equal to ? 3/4
Answers
Answer: D
Step-by-step explanation:
3/4 is equal to 0.75.
A is pretty easy. You just add the numerator and get 3/4. So, that is NOT the answer.
B is 9/12. If you divide 9 and 12, it gives 0.75, which is equal to 0.75. This NOT the answer.
C is 6/8 and simplifies into 3/4 so is this is NOT the answer.
D is 3/12 and when you dividere the umerator and the denominator, it gives 0.25 or 1/4, which isn’t equal to 3/4. This IS the answer.
Hope this helped!
The expression that is not equal to 3/4 will be 1/12 + 2/12. Then the correct option is D.

Let's check all the options. Then we have
A. 1/4 + 1/4 + 1/4, then the value of the expression is given as,
1/4 + 1/4 + 1/4 = 3/4
B. 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8, then the value of the expression is given as,
1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 = 6 / 8
1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 = 3 / 4
C. 3 / 12 + 6 / 12, then the value of the expression is given as,
3 / 12 + 6 / 12 = 9 / 12
3 / 12 + 6 / 12 = 3 / 4
D. 1 / 12 + 2 / 12, then the value of the expression is given as,
1/12 + 2/12 = 3 / 12
1/12 + 2/12 = 1 / 4
The expression that is not equal to 3/4 will be 1/12 + 2/12. Then the correct option is D.

Answers
Answer:

Step-by-step explanation:
d^2 -10d+16
-----------------------
d-8
Factor the numerator
( d-8)(d-2)
-------------------
d-8
The undefined values occur when the denominator is equal to zero
d-8 = 0
d= 8
This means d cannot equal 8
Now cancel like terms in the equation ( d-8)
This yields d-2
Answer: d - 2 and d cannot equal 8
Step-by-step explanation: To simplify this rational expression, start by factoring both the numerator and the denominator.
So factoring the numerator in this problem, we have a
trinomial that factors as the product of two binomials.
So we are looking for factors of +16 that add to -10 which are -8 and -2.
So we have (d - 8)(d - 2) in the numerator.
The denominator doesn't factor however.
So we have [tex]\frac{(d - 8)(d - 2)}{(d - 8)}[/tex] and the d - 8's cancel leaving us with d - 2.
The values d cannot be happen when the denominator is set equal to 0.
So we have d - 8 = 0 which means d = 8.
This means d = 8 wouldn't work!
