1.- En la cooperativa escolar se vendieron 296 refrescos en total. Si los refrescos chicos vendidos fueron el triple de los
medianos. ¿Cuántos se vendieron de cada uno?​

Answers

Answer 1

Answer:

222 small ones and 74 middle ones

Step-by-step explanation:

The computation is shown below:

Let us assume medium ones be x

so the small ones be 3x

And, the total is 296

So, the equation is

x + 3 x = 296

4x = 296

Medium ones = x = 74

And, the small ones is = 3 × 74

= 222

1. When Jack and Jill work together, they can carry a cooler of
water up a hill in 12 hours. When Jill works alone it takes her
7 fewer hours than when Jack works alone. How long would it
take Jack, working alone, to carry a cooler of water up a hill?

Answers

9514 1404 393

Answer:

  28 hours

Step-by-step explanation:

Let x represent Jack's time. Then Jill's is x-7. Together their rate of carrying water in hills per hour is ...

  1/x + 1/(x -7) = 1/12

Multiplying by 12x(x -7) gives ...

  12(x -7) +12x = x(x -7)

  x^2 -31x +84 = 0 . . . . . subtract the left side and simplify

  (x -3)(x -28) = 0 . . . . . . . . . . factor

  x = 3  or  x = 28 . . . . . . . . . . x-values that make the factors zero

We know the times must be longer than 12 hours, so the value x=3 is extraneous for this problem.

It takes Jack 28 hours to carry the cooler of water up the hill working alone.

How many solutions exist for the given equation?

zero

Answers

Answer:

one

Step-by-step explanation:

Given

[tex]\frac{1}{2}[/tex] (x + 12) = 4x - 1 ( multiply through by 2 to clear the fraction )

x + 12 = 8x - 2 ( subtract x from both sides )

12 = 7x - 2 ( add 2 to both sides )

14 = 7x ( divide both sides by 7 )

2 = x

There is one solution to the equation, that is x = 2

b) 2 26/47 horas.

c) 3 1/47 horas.

d) 4 36/47 horas.

Answers

Answer:

b) [tex]2\dfrac{26}{47}\ \text{horas}[/tex]

Step-by-step explanation:

Tiempo necesario para completar el trabajo en primera persona = 6 horas

Trabajo hecho en 1 hora = [tex]\dfrac{1}{6}[/tex]

Tiempo necesario para completar el trabajo por segunda persona = 8 horas

Trabajo hecho en 1 hora = [tex]\dfrac{1}{8}[/tex]

Tiempo necesario para completar el trabajo por tercera persona = 10 horas

Trabajo hecho en 1 hora = [tex]\dfrac{1}{10}[/tex]

El tiempo necesario para completar el trabajo juntos viene dado por

[tex]\dfrac{1}{\dfrac{1}{6}+\dfrac{1}{8}+\dfrac{1}{10}}=\dfrac{1}{\dfrac{47}{120}}\\ =\dfrac{120}{47}=2\dfrac{26}{47}\ \text{horas}[/tex]

El tiempo necesario para completar el trabajo juntos es [tex]2\dfrac{26}{47}\ \text{horas}[/tex].

A bridge being designed will cross the river at a right angle. The equation of the left bank of the river is j = 2x+8. The center of the bridge will pass through (0,2). What is the equation of the line representing the bridge?​

Answers

Answer:   y = (-1/2)x + 2

This is the same as y = -0.5x+2

==========================================================

Explanation:

Refer to the diagram below.

The blue line is the graph of y = 2x+8, which is the left bank of the river.

For now, ignore the y = (-1/2)x+2 in the diagram and pretend we don't know that just yet. The red line is the bridge and it's some linear equation in the form y = mx+b. We're told the bridge is perpendicular to the river, so the bridge must also be perpendicular to the riverbank.

The blue line has slope m = 2. Apply the negative reciprocal to this to end up with -1/2. This is the perpendicular slope, and the slope of the red line. Note how the two slopes (2 and -1/2) multiply to -1. Any two perpendicular lines will have their slopes multiply to -1, as long as neither line is vertical or horizontal.

Since we want the bridge to pass through (0,2), this must mean the y intercept is b = 2.

So with m = -1/2 and b = 2, we go from y = mx+b to y = (-1/2)x + 2 which is the equation of the bridge shown in red.

This is the same as y = -0.5x + 2 since -1/2 = -0.5
