Answer:

On 5 liters of petroleum he can go 100km.

He needs 37.5 liters of petroleum to go 750km.

Step-by-step explanation:

He goes 20km on 1 liter. Now we must find how far he can go on 5 liters.

1 * 5 = 5

20 * 5 = 100

The reason we multiplied was because we had to multiply 1 by 5 to get the number of liters of petroleum and what you to one side you must do to the other.

To find how many liters are needed to go 750km you must divide:

750/20 = 37.5

He needs 37.5 liters of petroleum to travel 750km.

Hope this helps! :)

Answer:

El orden de menor a mayor es:

1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4

La mediana es 3.

Step-by-step explanation:

En la ciudad se hizo la relación de hoteles según la lista de estrellas, la cual se ordena de menor a mayor. Entonces, el orden determinado es:

1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4

La mediana de un conjunto de números es el número medio en el conjunto, una vez que los números han sido ordenados de menor al mayor, o, si hay un número par de datos, la mediana es el promedio de los dos números medios.

En este caso el conjunto posee 38 datos. Cuando el número de observaciones es par es posible calcular la mediana como:

[tex]Mediana=\frac{n+1}{2}[/tex] donde n es la cantidad de observaciones.

Entonces:

[tex]Mediana=\frac{38+1}{2}[/tex]

Mediana= 19.5

Esto indica que el valor de la mediana se encuentra en la observación cuya posición esta entre la 19 y la 20.  Entonces el valor de la mediana será una media de los valores que están en la posición 19y 20. Estos números son 3 y 3. La media entre estos dos números es:

[tex]\frac{3+3}{2} =3[/tex]

La mediana es 3.

Answer:

Both processes are correct.

Step-by-step explanation:

Let the mile taken by Chase be 10miles .

He doubles it so it will be 20 and

20% of 20 will be 4

20-4 = 16km

Now Alex operations

(10/5 )*8 = 2*8= 16 km

In both cases the answer will be the same

1 mile = 1.60034 km

Now 10 miles = 16.00 34 km

which is the same as above.

Both the processes are correct.

C 2/3

Step-by-step explanation:

Answer:

The discriminant is 37

Answer: y = x + 40

Step-by-step explanation: y = x + 40

First of all, the line starts at the y-axis on 40, which means the y-intercept is 40.

Second, the slope, Rise over run. y2 - y1 / x2 - x1, which is = to 50 - 40 divided by 15 - 5. That is 10 over 10 or 10/10. The slope of that is 1 so the slope is just x.

There are a few possible answers and they are

y - 40 = 1(x - 0)

y - 50 = 1(x - 10)

y - 60 = 1(x - 20)

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

Explanation:

Pick two blue points from the graph. I recommend points that land on grid intersections so we can read the coordinates easily. Two such points are (0,40) and (10,50)

Use the slope formula to find the slope

m = (y2-y1)/(x2-x1)

m = (50-40)/(10-0)

m = 10/10

m = 1

The slope is 1.

Note how I subtracted the y coordinates, then did the same for the x coordinates in the same order, and divided the differences.

------------------

Since your teacher wants the answer in point slope form, we'll use this as our template

y - y1 = m(x - x1)

where m is the slope and (x1,y1) a the point the line goes through. We have infinitely many choices for (x1,y1) since there are infinitely many points on this line.

------------------

If we use (x1,y1) = (0,40), then we get

y - y1 = m(x - x1)

y - 40 = 1(x - 0)

which is one possible answer

------------------

If we use (x1,y1) = (10,50), then we get

y - y1 = m(x - x1)

y - 50 = 1(x - 10)

which is another possible answer

------------------

If we use (x1,y1) = (20,60), then we get

y - y1 = m(x - x1)

y - 60 = 1(x - 20)

which is another possible answer

------------------

So again there are multiple answers possible. The slope stays the same each time, but x1 and y1 change depending on which point you choose.

Problem 8

The triangles are congruent, which means their corresponding pieces must also be congruent.

Focus on the second equation above. We can further say

angle B = angle E

E = B

12x+30 = 50

12x = 50-30

12x = 20

x = 20/12

x = 10/6

----------------

Now move to the equation involving C and F to get

F = C

(y/2) - 10 = 40

y/2 = 40+10

y/2 = 50

y = 2*50

y = 100

----------------

And finally,

D = A

sqrt(z) = 90

z = 90^2

z = 8100

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

Problem 11

The radius of the circle is r = 5.

The area of the circle is A = pi*r^2 = pi*5^2 = 25pi

The diameter of the circle is 2*r = 2*5 = 10, which is the side length of the square because the circle is fit perfectly inside the square.

Since the square side length is 10, the area is 10^2 = 100

Subtract the two areas: large-small = square - circle = 100 - 25pi

We subtract the areas because we're basically kicking out the circle area when we don't shade it. Think of it like sawing out that portion of a wooden block perhaps.

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

Problem 19

Part (a)

The point P is directly below the center and it is on the circle.

The location of point P is (18,0) because the x coordinates of both points are the same (so that P is directly below the center) and P resides on the x axis. All points on the x axis have y coordinate 0.

------------------------------

Part (b)

The radius of the circle is r = 10 which is the distance from the center to point P.

The area of the circle is therefore A = pi*r^2 = pi*10^2 = 100pi

Answer: 100pi

Answer:

Not sure what you're equation is but this is how you would convert to slope intercept form:

Step-by-step explanation:

y=mx+b is slope intercept form where m is the slope and b is the y intercept. the x is just x so don't change that. graphing your equation might help you to convert. Hope this helps if I had the equation it would help more. :)

The quotient is 21. the correct answer is option 1) 21.

To find the quotient of 189 divided by 9, we divide 189 by 9.

When dividing 189 by 9, we find that 9 can be subtracted from 189 a total of 21 times without going into negative values. Therefore, the quotient is 21.

So, the correct answer is option 1) 21.

When we divide 189 by 9, the result is 21, which means that 21 is the number of times that 9 can be subtracted from 189 without remainder. The quotient represents the whole number part of the division, indicating the number of groups of 9 that can be formed from 189.

Answer:

false

Step-by-step explanation:

this is showing 2/-3

Answer: False.  

Step-by-step explanation:

The slope is the difference in the y coordinates of any two points being divided by the difference between the x coordinates of the same two points.

Using the point,  (0,5) and (3,3)  find the difference in the y coordinates and divide it by the difference in the x coordinates to find the slope.

y:  5 - 3 = 2  

x :  0 - 3 = -3

Slope:  -2/3

This is indeed true because line is going downright  so the slope has to  be negative.

Answer:

-3

Step-by-step explanation:

Slope of a line is "rise over run".  Pick two points on the line.  For example, (0,4) and (1,1).  As we move from the first point to the second, we move down 3 units and right 1 unit.  So the slope is -3/1 = -3.

Here's an algebraic approach.  If the two points are (x₁, y₁) and (x₂, y₂), then the slope is:

m = (y₂ − y₁) / (x₂ − x₁)

Plugging in our two points:

m = (1 − 4) / (1 − 0)

m = -3

The value of x is 30 if the triangles FGH and JKL are similar after using the property of the similarity triangles.

It is defined as the law to prove that the two triangles have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.

It is given that:

The triangle FGH and JKL are shown in the picture.

(x + 35)/20 = (x - 4)/8

Cross multiplication:

8(x + 35) = 20(x - 4)

8x + 280 = 20x - 80

20x - 8x = 280 + 80

12x = 360

x = 360/12

x = 30

Thus, the value of x is 30 if the triangles FGH and JKL are similar after using the property of the similarity triangles.
