Eight cars are to be parked in a row for viewing at a fair. Three of the cars are the same colour and are to be kept together in the viewing row. Determine the number of possible arrangements of the cars, given that the three cars of the same colour are kept together.

Answers

Answer:

720 possible arrangements.

Step-by-step explanation:

The possible arrangement of the cars, given that the three cars of the same color are kept together is 4320.

What is combination?

The combination is a way of selecting items from a collection where the order of selection does not matter.

We have,

Number of cars = 8

Number of cars that are the same in color = 3

Cars that are the same in color can be arranged = 3!

There are 8 cars such that,

1 2 3 4 5 6 7 8

Three cars of the same color are taken out and we have,

1  2  3  4  5

We see that there are six spaces = 6!

where we can put the same color cars together so,

The possible arrangement of the cars, given that the three cars of the same color are kept together:

= 3! x 6!

= 3 x 2 x 1  x 6 x 5 x 4 x 3 x 2 x 1

= 4320

Thus,

The possible arrangement of the cars, given that the three cars of the same color are kept together is 4320.

Solution: 14.3p – 32.24 = 127.92 14.3p – 32.24 + 32.24 = 127.92 + 32.24 14.3p = 160.16 StartFraction 14.3 p Over 14.3 EndFraction equals StartFraction 160.16 Over 14.3 EndFraction. p =

Answers

Answer:

p = 11.2

Step-by-step explanation:

Given equation is :

2.6(5.5p – 12.4) = 127.92

Using the distributive property :

14.3p - 32.24 = 127.92

Using addition property :

14.3p - 32.24 + 32.24= 127.92 + 32.24 (adding 32.24 to the both sides)

14.3p = 160.16

Using division property :

[tex]p=\dfrac{160.16}{14.3}\\\\p=11.2[/tex]

So, the value of p is 11.2

The endpoints of MN are located at M (-4, 4) and N (2,-2). What are the coordinates of the point that divides MN such that MP: PN is equal to 2: 1?

Answers

Given:

The endpoints of MN are located at M (-4, 4) and N (2,-2).

Point P divides the line segment MN such that MP: PN = 2: 1

To find:

The coordinates of point P.

Solution:

Section formula: If a point divides a line segment in m:n, then coordinates of that point are

[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]

Point P divides the line segment MN in 2:1. So,

[tex]P=\left(\dfrac{2(2)+1(-4)}{2+1},\dfrac{2(-2)+1(4)}{2+1}\right)[/tex]

[tex]P=\left(\dfrac{4-4}{3},\dfrac{-4+4}{3}\right)[/tex]

[tex]P=\left(\dfrac{0}{3},\dfrac{0}{3}\right)[/tex]

[tex]P=(0,0)[/tex]

Therefore, the coordinates of the point P are (0,0).

a rectangle is 25 feet long its area 375 square feet.
What is the perimeter of the rectangle

Answers

Area = length x width.

Divide the area by the length of find the width.

Width = 375/25 = 15 feet.

The perimeter is the sum

Of the 4 sides.

Perimeter = 25 + 25 + 15 + 15 = 80 feet.

The perimeter of a rectangle is 80 feet.

Given that, the length of a rectangle=25 feet and area of the rectangle=375 square feet.

We need to find the perimeter of a rectangle.

What is the formula to find the perimeter of a rectangle?

The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).

We know that, the area of a rectangle=length×width

Now, the area of a rectangle=25×width

⇒375=25×width

⇒Width=15 feet

So, perimeter = 2(25+15).

=80 feet

Therefore, the perimeter of a rectangle is 80 feet.

B. because angle Q is congruent to angle S. C. by the Reflexive Property of Equality. D. because PQR is an isosceles triangle.

Answers

Answer:

A. by the definition of perpendicular.

Explanation:

Indeed, in geometry, for lines to be termed as been perpendicular, it means that two lines met at a right angle (90 degrees).

From the attached image we could see that Segment PR is perpendicular to segment QS as it touches or meets with segment QS which follows the definition of perpendicular. Also, Angle QRP is a right angle because it is exactly 90 degrees.

The Quotient of x and 5 is greater than 22

Answers

Answer:

[tex]\frac{x}{5}[/tex] > 22

x = > 110

Step-by-step explanation:

This is the answer because:

1) The quotient of x and 5 means the answer to a division problem. Therefore, it's [tex]\frac{x}{5}[/tex]

2) Greater than 22 means the quotient has to be anything greater than 22. Therefore it is > 22

3) Finally, x is equal to anything greater than 110 because 22 x 5 is 110. Therefore, x has to equal anything greater than 110

The final answer is:

[tex]\frac{x}{5}[/tex] > 22

x = > 110

Use the diagram above. Is AB congruent to DE? To find AC in problem 3, suppose you subtract -2 from 5. do you get the same result? Why?

Answers

Answer:

(a) Segments AB and De are not congruent since their lengths are not equal.

(b) Yes, you get the same result. In both cases you must take the absolute value of the difference of the coordinates giving you the same result no matter in which order you subtract the coordinates of the points.

Step-by-step explanation:

(a)

To find the distance between any two points on the number line, take the absolute value of the difference of the coordinates of the points.

The coordinate of point P is p. The coordinate of point Q is q. PQ or QP, the distance between points P and Q, is:

PQ = QP = |p - q| = |q - p|

It does not make a difference in which order you find the diffeence of the coordinates.

Look at points A and B.

Point A has coordinate -2.

Point B has coordinate 3.

AB = |-2 - 3| = |-5| = 5

Now look at points D and E.

Point D has coordinate 10.

Point E has coordinate 14.

DE = |10 - 14| = |-4| = 4

AB = 5; DE = 4

Answer: The lengths of segments AB and DE are not equal, so the segments are not congruent.

(b)

The coordinate of point A is -2.

The coordinate of point C is 5.

AC = |-2 - 5| = |-7| = 7

If you subtract -2 from 5, and then take the absolute value, you get:

AC = |5 - (-2)| = |5 + 2| = |7| = 7

Again you get 7. The order in which you subtract the coordinates of the points does not affect the result since you take the absolute value of the difference in both cases.

AC =

Please help I am horrible at math! Ye is riding home from a friend's house. After 5 minutes he is 4 miles from home, after 15 minutes Ye is 2 miles from home. Which equation models his distance from home y, in terms of minutes, x?
A)y=−0.2x+ 5
B)y=11/7x-27/7
C)y = 11 7 x − 27 7
D) y= 5x− 0.2 y=0.2x

Answers

Answer:

y=-0.2x+5. Correct choice: A)

Step-by-step explanation:

Modeling With Equations

Let's call x the number of minutes and y the distance from home. The correct model should meet both conditions:

After 5 minutes, Ye is 4 miles from home. This is the ordered pair (5,4)

After 15 minutes, Ye is 2 miles from home. This is the ordered pair (15,2)

A) y=-0.2x+5. Testing the first point (5,4): y=-0.2*5+5=4. Correct

Testing the second point (15,2): y=-0.2*15+5=2. Correct

This is the correct choice.

B) y=11/7x-27/7. Testing the first point: (5,4) y=11/7*5-27/7=4. Correct

Testing the second point (15,2). y=11/7*15-27/7=138/7. Incorrect

Incorrect choice.

C) This equation is equal to the choice B), thus this one is incorrect.

D) y=5x-0.2. The first point (5,4) yields to:

4=5*5-0.2=24.8 Incorrect.

Step-by-step explanation:

Quadratic Formula

Given the second-degree equation:

[tex]ax^2+bx+c=0[/tex]

The solutions of the equation can be obtained by applying the formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

The equation to solve is:

[tex]3x^2-7x-3=0[/tex]

Which means the values of the coefficients are: a=3, b=-7, c=-3. Substituting the values in the formula:

[tex]\displaystyle x=\frac{-(-7)\pm \sqrt{(-7)^2-4(3)(-3)}}{2(3)}[/tex]

[tex]\displaystyle x=\frac{7\pm \sqrt{49+36}}{6}[/tex]

[tex]\displaystyle x=\frac{7\pm \sqrt{85}}{6}[/tex]

There are two real solutions for this equation:

[tex]\displaystyle x_1=\frac{7+ \sqrt{85}}{6}[/tex]

[tex]\displaystyle x_2=\frac{7- \sqrt{85}}{6}[/tex]

The approximate values of both roots are:
