Answer:

Assuming the spinner has 6 parts: 1/6 chance of landing on 4 (theorectical probability)

Step-by-step explanation:

Since you did not give me the bar graph, I cannot see the results of the experiment and so I assume that there are 6 equal parts in the spinner.

To figure out the Ex. Pro.,  do favorable outcome/possible outcome.

Hopes this makes sense!

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:

7 minutes

Step-by-step explanation:

The computation of the number of minutes that climbs the stairs tomorrow is shown below:

Given that

He claimed 1000 stairs in 25 minutes

So for 280 stairs, he would take

= 280 × 25 minutes ÷ 1000 minutes

= 7000 ÷ 1000

= 7 minutes

hence, 7 minutes would be taken

The same is to be considered

Answer:

7 minutes

Answer:

3

Step-by-step explanation:

18 + 13 is 31.

31 is more than 28, and for the people who learn both languages(x), we can do 31-28 = x. 31-28 is 3, so the answer is B, or 3.

Answer:

hi

Step-by-step explanation:

firstly we must divide the shape like this

and the area of first rectangular is 27 m²( 9m × 3m)

then second rectangular's area is 48m²( 12m × 4m and we found 4m from 9-5)

the third rectangular's area is 10 m² ( we found it from 9-4)

Total is 27+48+10=85 m²

Answer:

$4.00

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

Answer: 135 I yhink

Not 100% sure though

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 distance between the points is 9.219544457292887

Step-by-step explanation:

Answer:

x=2, y= 4

Step-by-step explanation:

Equation 1 is 2x-4y = -12

Equation 2 is 2x+y = 8

Subtracting the two equations gives -4y-y = -12-8 (The 2x and the other 2x cancel each other out).

Simplifying we get -5y = -20 and y =4

Substituting y =4 into original equation back we get 2x -4(4) =-12

This equals 2x -16 =-12 and 2x = 4 and x =2

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

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:

the value of x = -3

Step-by-step explanation:

10 (x-5) = -80

10x - 50 = -80

10x = -30

x = -3

CHECK:

10 ( -3 - 5) = -80

10 (-8) = -80

-80 = -80
