Un grupo de 14 mujeres y 16 hombres
formará parejas de trabajo. ¿cuántas
parejas se pueden formar?
Responder:
14 parejas
Explicación paso a paso:
Una pareja es la combinación de un hombre y una mujer.
Dado que la cantidad de hombres reemplaza a la de mujeres en 2, esto significa que podemos emparejar a todas las mujeres con 14 hombres (excluyendo 2 hombres)
Promedio = (14 + 16) / 2
Promedio = 30/2
Promedio = 15
Como no podemos para un número impar de parejas sino pares, la cantidad de parejas que se pueden formar será:
No de parejas = promedio - 1
No de parejas = 15-1
No de parejas formadas = 14
Usando el concepto de proporción, tiene-se que 15 parejas se pueden formar.
-------------------------
Para solucionar esta pregunta, usa-se proporciones, a partir de una regla de tres.Una pareja es formada por 2 personas.En todo, tiene-se 14 - 16 = 30 personas. Quantas parejas?La regla de tres es:
1 pareja - 2 personas
x parejas - 30 personas
Aplicando multiplicacción cruzada:
[tex]2x = 30[/tex]
[tex]x = \frac{30}{2}[/tex]
[tex]x = 15[/tex]
Se pueden formar 15 parejas.

Please select the best answer from the choices provided
Answer:
D, C, B, A
Step-by-step explanation:
Given the prices below:
Store A: price $99.99 and discount of 15%
15% discount :
Discounted price : (1 - 0.15) * $99.99 = $84.99
Store B: price $95.99 and discount of 12%
12% discount :
Discounted price : (1 - 0.12) * $95.99 = $84.47
Store C: price $90.99 and discount of 10%
10% discount :
Discounted price : (1 - 0.10) * $90.99 = $81.89
Store D: price $89.99 and successive discounts of 5% and 5%
5% discount :
Discounted price : (1 - 0.05) * $89.99 = $85.4905
5% discount :
(1 - 0.05) * $85.4905 = $81.22

14/5x23/7
14/5x7/23
98/115
Answer:
it is 98/115 but I dont know what the simplified part of it is
Step-by-step explanation:
2 and 4/5 turns into 14/5. 3 and 2/7 turns into 23/7. keep 14/5 the same but flip 23/7 over to be 7/23. then multiply it and you get 98/115
.3333333333 is equivalent to
which fraction: 3/33 or 3/1 or
33/33 or 1/3
Answer:
1/3
Step-by-step explanation:
If you times 1/3 by 3, you will end up with one whole (1).
If you times .3333333... by 3, you will end up with a number that is pretty close to "1."
3/33 equals 0.090909... or 1/11, so this answer is not right.
3/1 equals 3 while 33/33 equals 1.

a Given p(x) = X+41, what is (-10)?
Answer:
p(-10) = 31
Step-by-step explanation:
Plug in -10 as x into the equation, and solve
p(x) = x + 41
p(-10) = -10 + 41
p(-10) = 31
Given : p(x) = x + 41
We have to find value of p(-10)[tex].[/tex]
➙ p(x) = x + 41
By substituting x = (-10), we get
➙ p(-10) = (-10) + 41
➙ p(-10) = 41 - 10
➙ p(-10) = 31

Answer:
[tex] \huge \boxed{x = - 1}[/tex]
Step-by-step explanation:
[tex] \frac{2x - 10}{4} = 3x \\ [/tex]
Multiply through by 4 to eliminate the fraction
That's
[tex]4 \times \frac{2x - 10}{4} = 4(3x) \\ 2x - 10 = 12x[/tex]
Subtract 12x from both sides of the equation
[tex]2x - 12x - 10 = 0 \\ - 10x - 10 = 0 \\ - 10x = 10[/tex]
Divide both sides by - 10
[tex] \frac{ - 10x}{ - 10} = \frac{10}{ - 10} \\ [/tex]
We have the final answer as
x = - 1Hope this helps you

6m+6+7(1-3m)=-32
Answer:
m=15
Step-by-step explanation:
BODMAS
6m+6+7-3m=-32
collect like terms
6m-3m+6+7=-32
3m+13=-32
3m=-32-13
3m=45
m=45/3
m=15
Answer:
m = 3
Step-by-step explanation:
6m + 6 + 7(1 - 3m) = -32 (distruibute)
6m + 6 + 7 - 21m = -32 (collect like terms)
-15m + 13 = -32 ( subtract 13 on both sides to get rid of it on the left side)
-15m = -45 (divide by -15 on both sides to get m alone)
m = 3

What are the intercepts of the linear function shown?
A) x-intercept is -2 and y-intercept is -2
B) x- intercept is -2 and y-intercept is 4
C) x-intercept is 2 and y-intercept is 4
D) x- intercept is 2 and y-intercept is -4
Look at the image!!!!
Answer:
(see explanation below)
Step-by-step explanation:
The x-intercept is where the line intersects with the x-axis. If you look at the given line in the coordinate plane, you can see that the line intersects the x-axis at (-2, 0). Therefore, the x-intercept is -2.
The y-intercept is where the line intersects with the y-axis. If you look at the given line in the coordinate plane, you can see that the line intersects the y-axis at (0, 4). Therefore, the y-intercept (also represented by the variable b) is 4.
