When the train on one route stop there every 9 minutes and trains on the other route stop there every 6 minutes, the time when they will stop at same time is 18 minutes.

From the information, the train on one route stop there every 9 minutes and trains on the other route stop there every 6 minutes.

Therefore, the time when will they stop at same time will be the lowest common multiple for 9 and 6. This is 18. Therefore, 18 minutes is the appropriate answer.

Therefore, the the time when they will stop at same time is 18 minutes.

Trains on two different routes at the same train station. Train on one route stop there every 9 minutes and trains on the other route stop there every 6 minutes. When will they stop at same time?

Answer:

x = five over two and x = −3

Step-by-step explanation:

Let's solve your equation step-by-step.

2x2+x=15

Step 1: Subtract 15 from both sides.

2x2+x−15=15−15

2x2+x−15=0

Step 2: Factor left side of equation.

(2x−5)(x+3)=0

Step 3: Set factors equal to 0.

2x−5=0 or x+3=0

x=5/2 or x=−3

The slope Intercept and the standard form of the equation are y = -1/2x - 3 and x + 2y = -6

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The given parameters are

y= -3 and x=-6

The above represent the y and the x intercepts

i.e.

y-intercept = -3

x-intercept = -6

A linear equation is represented as

y = mx + c

Where

c = y-intercept = -3

So, we have

y = mx - 3

At x-intercept = -6, we have

y = 0

So, we have

0 = m(-6) - 3

This gives

m = -1/2

So, we have

y = -1/2x - 3 --- slope-intercept form

Multiply through by 2

So, we have

2y = -x - 6

Rewrite as

x + 2y = -6 ----- standard form

Hence, the slope Intercept and the standard form of the equation are y = -1/2x - 3 and x + 2y = -6

Answer: to the nearest hundredth

I hope this helps!

Answer:

Step-by-step explanation:

You want to see two other ways to write the ratio 3:8.

A ratio is a way of saying that some number of one thing is always associated with some (often different) number of another thing. The two things may or may not be measured with the same units, and may or may not refer to parts of the same object.

Here, we're concerned with how we write a ratio. One way is shown in the problem statement:

  3 : 8 . . . . . . . . using a colon

Two other ways to write the same ratio are ...

  3 to 8 . . . . . . using the word "to"

  3/8 . . . . . . . . using a fraction bar

__

Additional comment

A ratio is in "simplest form" if the numbers involved are mutually prime (have no common factors).

Sometimes an extended ratio is useful for specifying the relationship between more than two measures, for example, 3 : 8 : 5.

The required solution of the number to the nearest 10 , 100 and 1000 is 1260, 1300, 1000.

A number that is easily multiplied, divided, etc., and especially a number that ends in zero.

Given:

A school has 1256 pupils write this number to the nearest 10 , 100 and 1000

According to given question we have

⇒ Round off to 10 for 1256 is 1250 or 1260 but nearest to 1256 is 1260.

⇒  So, round off to the nearest 10 is 1260.

⇒ Round off to 100 for 1256 is 1200 or 1300 but nearest to 1260 is 1300.

⇒  So, round off to the nearest 100 is 1300.

⇒  Round off to 1000 for 1256 is 1000 or 2000 but nearest to 1256 is 1000.

⇒  So, round off to the nearest 1000 is 1000.

∴  The answer is 1260,1300,1000.

Therefore, the required solution of the number to the nearest 10 , 100 and 1000 is 1260, 1300, 1000.

Based on the number of people employed in education and health service industries in 2009, the number of new jobs that will be gained between 1/2009 and 1/2016 is b. 2,826,800 people.

The number of total jobs in 2016 can be found as:

= Number of jobs in education and health service industries x (1 + rate of increase)

= 19,200,000 x (1 + 14.8%)

The value of sinФ = 0.139 for the given cosФ = 0.139 and tanФ > 0.

The given trigonometric function is-

cosФ = 0.139.

We know the relation of sin and cos functions.

sin²Ф + cos²Ф = 1

Thus,

sinФ = √(1 - cos²Ф)

Put the value of cosФ = 0.139

sinФ = √(1 - 0.139²)

sinФ = √0.981

sinФ = 0.139

Thus, the value of the trigonometric function sinФ = 0.139.

What is a function ?

A function is a relationship between inputs and outputs where each input has precisely one output and the output can be linked to its input.

It is given that , a function which represents rate % is f(t) = 10.72 × [tex](0.9t + 10)^{0.3}[/tex]. Also , t = 0 corresponding to the year 2000.

The rate % of Americans age 55 and older changing at the beginning of 2008 i.e., t = 8 , rounded off to four decimal places will be :

So : f(t) = 10.72 × [tex](0.9* 8 + 10)^{0.3}[/tex]

f(t) = 10.72 × [tex](7.2+ 10)^{0.3}[/tex]

f(t) = 10.72 × [tex](17.2)^{0.3}[/tex]

f(t) = 10.72 × 2.347

f(t) = 25.1682 % per year

The rate % of Americans age 55 and older changing at the beginning of 2017 i.e., t = 17 , rounded off to four decimal places will be :

f(t) = 10.72 × [tex](0.9* 17 + 10)^{0.3}[/tex]

f(t) = 10.72 × [tex](15.3 + 10)^{0.3}[/tex]

f(t) = 10.72 × [tex](25.3)^{0.3}[/tex]

f(t) = 10.72 × 2.6359

f(t) = 28.2573 % per year  

The rate % of Americans age 55 and older changing at the beginning of 2017 rounded off to two decimal places will be :

The minimum cost is $210.

Forgetting the situation for just a second, we can take a look atthe equation.

c(x)=x^2-40x+610

It is a parabola that opens upward and has a minimum value.

That minimum value will be the minimum cost of the taco stand.

The equation x=-b/2a gives you the axis of symmetry of theparabola. Basically, it goes right down the middle of the parabola,right through its minimum

In the equation  c(x)=x^2-40x+610, a=1 and b=-40

x=-b/2a

x=-(-40/2(1)) = 20

So 20 tacos should be sold to achieve the minimum cost.

To find the cost, return to the original equation.

c(x)=x^2-40x+610

c(20)=(20)^2-40(20)+610 = 210

So the minimum cost is $210.

The minimum cost of the function is $210.

A function is defined as the representation of  a set of variables known as the domain which are mapped onto another set of variables called the range.

The most common function is of the form y = f(x) , where x is the independent variable and y is the dependent variable and f(x) is the function.

The given function is of the form:

c(x) = x² - 40 x + 610

To find the maximum or minimum point of the function we find the second degree derivative of the function.

c'(x)=2x -40

Now we find the second degree derivative.

c"(x) = 2 > 0 so we know that c(x) is minimum at x for c'(x)=0.

Therefore c'(x) = 0

or , 2x-40 = 0

or , x = 20

Now the minimum value of the function is

c(20) = 20² - 40 (20) + 610

or, c(20) = 400 - 800 + 610

or, c(20) = 210

Hence the minimum value of the function is $210.

The co-ordinates of the image after translation are R"(2,1),S"(-1,7) and T"(2,7).

A translation is a geometric change in Euclidean geometry that involves moving each point in a figure, shape, or space by the same amount in one direction. A translation can also be thought of as moving the origin of the coordinate system or as adding a constant vector to each point.

When a point is rotated 90° counter clockwise, the co-ordinates of the point say A(x ,y) changes to A"(y,-x).

The given co-ordinates are:  R(-7, - 5), S(-1,- 2), and T(-1.- 5 ).

So when this co-ordinates are translated by rotating 90° counterclockwise.

R(-7, -5) →R'(5,-7)

S(-1,- 2) →S'(2,-1)

T(-1.- 5) →T'(5,-1)

Now the figure is translated 3 units left and 8 units up the new co-ordinates is given by (x-3,y+8).

So when this co-ordinates are translated the new co-ordinates are:

R'(5,-7)→R"(2,1)
