Answer:

Train A is travelling at a speed of 12.857 miles per hour and train B at a speed of 9.643 miles per hour.

Step-by-step explanation:

Let suppose that train A begins in position [tex]x = 0\,mi[/tex] and the train B in position [tex]x = 1.5\,mi[/tex], if [tex]v_{B} = \frac{3}{4}\cdot v_{A}[/tex] and both trains move at constant speed, then we have  the following kinematic equations:

Train A

[tex]x_{A} = x_{A,o}+v_{A}\cdot t[/tex] (1)

Train B

[tex]x_{B} = x_{B,o}-v_{B}\cdot t[/tex] (2)

If both trains meet each other, then [tex]x_{A} = x_{B}[/tex]. If we know that [tex]x_{A,o} = 0\,mi[/tex], [tex]x_{B,o} = 1.5\,mi[/tex], [tex]v_{B} = \frac{3}{4}\cdot v_{A}[/tex] and [tex]t = \frac{1}{15}\,h[/tex], then we have the following expression:

[tex]x_{A,o}+v_{A}\cdot t = x_{B,o}-v_{B}\cdot t[/tex]

[tex]x_{A,o} + v_{A}\cdot t = x_{B,o} - \frac{3}{4}\cdot v_{A}\cdot t[/tex]

[tex]\frac{7}{4}\cdot v_{A}\cdot t = x_{B,o}-x_{A,o}[/tex]

[tex]v_{A} = \frac{4\cdot (x_{B,o}-x_{A,o})}{7\cdot t}[/tex]

[tex]v_{A} = 12.857\,\frac{mi}{h}[/tex]

Then, the speed of the train B is:

[tex]v_{B} = 9.643\,\frac{mi}{h}[/tex]

Train A is travelling at a speed of 12.857 miles per hour and train B at a speed of 9.643 miles per hour.

Complete question

A circle's circumference is approximately 44 cm.

Complete each statement using one of these values: 7, 11, 14, 22, 88, 138, 154, 196, 380, 616.

The circle's diameter is approximately cm.

The circle's radius is approximately cm.

The circle's area is approximately cm2.

Circumference of the circle =2πr

r is the radius of the circle

Circumference of the circle = 2(3.14)r

44 = 2(3.14)r

22 = 3.14r

r = 22/3.14

r = 7.0cm

The circle's radius is approximately 7cm.

Since diameter = 2r

diameter = 2 * 76

diameter = 14cm

The circle's diameter is approximately 14cm.

Area of the circle = πr²

Area of the circle = 3.14(7)²

Area of the circle = 3.14(49)

Area of the circle = 153.86sq.cm

The circle's area is approximately 154cm^2.

Answer:

√53

Step-by-step explanation:

Formula

d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )

Givens

x1 = -5

x2 = -3

y1 = 6

y2 = - 1

Solution

d = sqrt( ( -3 - -5)^2 + (-1 - 6)^2 )

d = sqrt( ( -3 + 5)^2 + (-7)^2 )

d = sqrt( 2^2 + 49)

d = sqrt(4 + 49)

d = sqrt(53)

Answer:

18 and 74 are true.

Step-by-step explanation:

So we want to solve this inquality. [tex]13+4x> 75\\[/tex] We subtract 13 from the left and the right. It leaves us with [tex]4x>62[/tex]. Then we want the x by itself so we divide the 4 from 4x and 4 from 62. We get [tex]x> 15 \frac{1}{2}[/tex]. So 15.5 is false since its not greater than. 0 is not a solution. 18 and 74 are true. I'm sorry if this is wrong.

Answer:

4 1/6 cups of the smoothie were left.

Step-by-step explanation:

The LCD here is (3)(4) = 12.

Thus, 5 2/3 cups equals 5 8/12 and 1 3/4 cups equals 1 6/12 cups.

Subtract 1 6/12 cups from the original 5 8/12 cups.  We get:

5 8/12

-1  6/12

-----------

 4 2/12, or 4 1/6.

4 1/6 cups of the smoothie were left.

Answer:

-9 is the answer

Step-by-step explanation:

So we know that the temperature was 2 degrees Fahrenheit in the morning. It dropped by 11 degrees, meaning -11 degrees.

2 + (-11) = ?

2+ (-11) = -9

When he woke up, the temperature was -9 degrees.

Hope this helped :)

Answer:

The quotient decreases

Step-by-step explanation:

Give the expression :

10 / d

What happens to the expression as d increases. from small positive to large positive ;

d in the expression is the denominator ;the value obtained by dividing the numerator by the denominator is the quotient.

Since the value of the numerator is constant ;

As the value of d increases, the quotient obtained becomes smaller `

For instance,

Let

d = 2;

10 /2 = 5

d = 3

10 / 3 = 3.333

d = 4

10 / 4 = 2.5

And the trend continues

Step-by-step explanation:

Answer:

y = -x + 4

Step-by-step explanation:

Mathematically, the equation of a straight line is;

y = mx + b

where m is the slope and b is the y-intercept

from the plot, the y intercept is 4

So we have;

y = mx + 4

To get the value of m, we substitute the coordinates of any point and solve for m

we select the point; (4,0)

so;

0 = m(4) + 4

4m = 0-4

4m = -4

m = -1

so the equation of the line is;

y = -x + 4

No

Answer:

Ryan: 25 + 10h Alex: 20 + 11h

Mr. Smith should choose Alex - see below for reasoning

Step-by-step explanation:

The set-up fee does not change. It has no variable because it's already chosen. However, $/hour has a variable because the more hours a photo session takes, the more this number will increase when multiplied. Mr. Smith provides a good example of this. In his situation, h = 2 because his photo session will take two hours. If he hired Ryan, it would be $25 in set-up fees and then ten dollars per hour (h): [tex]25+10(2)[/tex] which totals out to $45. If he hired Alex, he would pay $20 for set-up fees and eleven dollars an hour (h): [tex]20+11(2)[/tex] which totals out to $42. So, Mr. Smith can save a few bucks if he hires Alex.

However, if someone expected hours and hours of photos - say, a fourteen-hour long photo session - then Ryan would be a better choice. His price would be [tex]25+10(14)[/tex] which totals to $165. Alex's price would be [tex]20+11(14)[/tex] which totals to $174. But I doubt anyone is going to want a fourteen-hour photo shoot, and I don't think Ryan nor Alex would want to do that either...

Answer:

= 1/26

Step-by-step explanation:

Use Division Distributive Property:

(x/y)^a = x^a/y^a

(^, That means to the power of exponents.)

Then you Simplify  6^3 to 216

Then you will get 1 over 216.
