Answer:

To find the scale factor, we simply create a ratio of the lengths of two corresponding sides of two polygons. If the ratio is the same for all corresponding sides, then this is called the scale factor and the polygons are similar.

Answer:

AM = 26

Step-by-step explanation:

AM = MC

x+20 = 5x-4

Subtract x from each side

x+20-x = 5x-x-4

20 = 4x-4

Add 4 to each side

20+4 = 4x-4+4

24 = 4x

Divide by 4

24/4 = 4x/4

6 =x

We want AM

AM = x+20

       =6+20

      =26

Answer:

26

Step-by-step explanation:

x+20=5x-4

x+24=5x

24=4x

x=6

x+20

substitute 6 for x

6+20

26

Answer:

56 cubic inches

Step-by-step explanation:

Volume of cube box = 6^3 = 6 *6*6 = 216 , Volume of rectangular box = 10*4*4 = 160 . Difference = 216 - 160 = 56 cubic inches. 56 cubic inches greater is the volume of the cube-shaped box than the rectangular box.

Answer:

Step-by-step explanation:

cube volume=side^3

given that the side is 6, the volume is 6^3 or 216 cubic inches

volume regular rectangular prism=length times width times height

given that length=10, width is 4 and height is 4, volume=10*4*4=160 cubic inches

how much greater

216-160=56

it is 56 cubic inches greater

this is ur answer buddy]

1350 (dont take my word for it, but i belive this is right)

Answer:

1350 (I did it on khan and I got it correct)

Step-by-step explanation:

Answer:

$300

Step-by-step explanation:

10% = .1 and each TV costs 120 so .1*120=12 then you take 12*25 since 12 is the money he makes for seeling the tv multiplied by the total TV's sold and you get 300 so Mike makes $300

Answer:

300 just cross multiply to get the answer.

Answer:

5 units

Step-by-step explanation:

I used the pythagorean theorem (a^2 + b^2 = c^2) to find the answer. I put 3 in a and 4 in b. I squared them and got 9 + 16 = 25. I found the square root of 25 which is 5 and that is my answer.

Step-by-step explanation:

Total marbles = 2 + 4 +1 + 8 = 15 marbles

Probability of blue marble = 4 / 15

Probability of green marble = 2 / 15

Answer:

4/105

Step-by-step explanation:

Total number of marbles: 2 + 4 + 1 + 8 = 15

Number of blue marbles: 4

First drawing:

p(blue marble) = 4/15

Now there are 14 marbles left.

Number of green marbles: 2

p(green marble) = 2/14 = 1/7

p(blue then green) = p(blue) * p(green) = 4/15 * 1/7 = 4/105

Answer: 4/105

Answer:

  5.  A) two solutions

  6.   one solution

Step-by-step explanation:

5. A graph shows the curve has two x-intercepts, so two solutions. You can also figure this by looking at the discriminant:

  b^2 -4ac = (7)^2 -4(-4)(8) . . . . a positive number

When the discriminant is positive, there are two real solutions.

6. The equation factors as ...

  0 = 3(x +3)^2

This will have one real solution at x=-3.

3.5/v^2

Step-by-step explanation:

-21v^6/-6v^8

-21/-6=3.5

v^6-v^8=-2

since -2 cannot be expressed as v^-2 it must be expressed as 1/v^2

so 3.5/v^2 is your answer

Answer:

7/2v^2

Step-by-step explanation:

7/2v^2 is the answer to the problem.

Answer:

For a the answer is 1/20 or 5%. For b the answer is 6/20 or 30%.

Step-by-step explanation:

a) There are 20 spots the dart can land on. To land on one specific spot, it would be 1/20. 1 spot out of 20 spots.

b) There are 20 spots the dart can land on. To land on any of the 6 spots, it would be 6/20. 6 spots out of 20 spots.

Answer:

126 in^2

Step-by-step explanation:

The area of a trapezoid is found by

A = 1/2 (b1+b2) h

A = 1/2 ( 12+16)*9

A = 1/2 (28) *9

  = 126

Answer:

126 ^2 in

(12)+(16)/2 * (9)

Area= a+b/s(h)

Step-by-step explanation:

The correct answer would be option #2!

The following best describes the motion of the car shown is,

⇒ It travels for 3 hours, then stops for 1 hour, and finally travels again for 1 hour.

The correct option is (B).

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Now, From 0-4 the graph is uniformly increasing which represents 3 hours that's it's moving.

Then from 2-3 there no increment or decrement which represents it is in rest.

Then, from 4 - 5 the graph is uniformly increasing again which represents 1 more hours it is moving.

Hence, We get;

⇒ It travels for 3 hours, then stops for 1 hour, and finally travels again for 1 hour.

Answer:

y = 2x - 18

Step-by-step explanation:

There are lots of different methods to do these types of questions, but this is the way i like to do it.

Coordinate (x1, y1) : (4, -10) and Gradient (m): 2

Start with this generic equation:

y- y1 = m(x-x1)

Substitute in the values they have given you:

y - (-10) = 2(x-4)

This becomes:

y + 10 = 2x - 8

Keep solving by moving the 10 over to the other side:

y = 2x -8-10

y = 2x - 18

An easy way to double check:

1) the coefficient of x is the slope. We got 2x, and the slope is 2, so that's correct.

2) Substitute x=4 into the equation, and we get -10, which is the exact coordinate that they gave us. This is also right.

Hope this helped : )

Answer:

2

Step-by-step explanation:

We can find the slope by

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

    = (4-2)/(-1 - -2)

    = (4-2)/( -1 +2)

    =2/1

   = 2

Answer:

2

Step-by-step explanation:

slope= [tex] \frac{y1 - y2}{x1 - x2} [/tex]

Thus, slope of the line

[tex] = \frac{4 - 2}{ - 1 - ( - 2)} \\ = \frac{2}{2 - 1} \\ = \frac{2}{1} \\ = 2[/tex]

Step-by-step explanation:

In the first row, there are 5 players in total, 4 of them practice extra time, then 5 - 4 = 1 player does not practice extra time.

In the second row, there are 5 players in total, 2 of them practice extra time, then 5 - 2 = 3 players do not practice extra time.

In the third row, there are 8 players in total, 2 of them practice extra time, then 8 - 2 = 6 players do not practice extra time.

We finally add up each column, to complete the table.
