a bag contains 5 red balls and some Blue Balls if the probability of drawing a blue ball is double that of red ball find the number of a blue balls in the back​

Answers

Answer 1

Answer:

10

Step-by-step explanation:

Let the number of blue balls be x.

Number of red balls = 5

Total number of balls = x + 5

P (getting a red ball)  = 5/x+5

P (getting a blue ball)  = x/x+5

Given that

2(5/x+5) = x/x+5

10(x+5) = x^(2) +5x

x^(2)-5x-50=0

x(x-10)(x+5)

Now either x-10 = 0 or x+5= 0

But number of balls cannot be negative.

Hence, the number of blue balls is 10.

What is the area of the enlarged rectangle?
120 in.²
720 in.²
2,400 in.²
14,400 in.²

Answers

Answer:

[tex]120in.^{2}[/tex]

To find the enlarged value, you have to multiply.

So, let's multiply 20 by 6, since it was enlarged by 6.

20 x 6 = 120.

So, the answer to the question is 120in.

Hope this helps you!

Answer:

Multiply 20 by 6 and then find the square of your answer

20×6=120

120^2= 14400

Plot J(-2,8), K(0,8), L(1,0), and M(1,-2) in a coordinate plane. Then determine whether JK and LM are congruent. A. Cannot be determined from the information given. O B. Cannot use Ruler Postulate for this problem. OC. JK and LM are congruent. D. JK and LM are not congruent.​

Answers

Answer:

C. JK and LM are congruent

Step-by-step explanation:

Given the coordinates J(-2,8), K(0,8), L(1,0), and M(1,-2), in other to determine whether JK is congruent to LM, we need to determine if the length of side JK and LM are equal i.e JK = LM

To get JK:

We will find the distance between the coordinates J(-2,8), K(0,8) to get the length JK using the formula:

JK =√(x2-x1)²+(y2-y1)²

JK = √(0-(-2))²+(8-8)²

JK = √2²+0²

JK = √4

JK = 2

For the length of LM with coordinate L(1,0), and M(1,-2)

LM = √(1-1)²+(-2-0)²

LM = √0²+(-2)²

LM = √0²+2²

LM = √0+4

LM =√4

LM = 2

Since JK = LM = 2 units, this means that JK and LM are congruent.

A coordinate plane with two polygons is shown. Polygon EFGH has vertices E at 1 comma 1, F at 1 comma 4, G at 5 comma 4, and H at 4 comma 1. Polygon E prime F prime G prime H prime has vertices at E prime negative 1 comma 2, F prime negative 4 comma 2, G prime negative 4 comma 6, and H prime at negative 1 comma 5. What set of transformations is performed on EFGH to form E′F′G′H′?

Answers

Answer:

B. A translation 1 unit to the right followed by a 90-degree counterclockwise rotation about the origin

Step-by-step explanation:

Polygons EFGH and E′F′G′H′ are shown on the coordinate grid:

What set of transformations is performed on EFGH to form E′F′G′H′?

A. A translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin

B. A translation 1 unit to the right followed by a 90-degree counterclockwise rotation about the origin

C. A 90-degree clockwise rotation about the origin followed by a translation 2 units to the right

D. A 90-degree clockwise rotation about the origin followed by a translation 2 units to the left

Answer: Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, dilation and rotation.

If a point X(x, y) is translated a units right and b units up, the new location is (x + a, y + b) also If a point X(x, y) is translated a units left and b units down, the new location is (x - a, y - b)

If a point X(x, y) rotated 90-degree counterclockwise about the origin, the new location is X'(-y, k)

Polygon EFGH has vertices E(1, 1), F(1, 4), G(5, 4), and H(4, 1). If the polygon is translated 1 unit right, the new location is E*(2, 1), F*(2, 4), G*(6, 4) and H*(5, 1).

If it is then rotated 90-degree counterclockwise about the origin, the new location is E'(-1, 2), F'(-4, 2), G'(-4, 6) and H'(-1, 5)

Step-by-step explanation:

This symbol is called a tilde. In symbolic logic (a field of math

example, ~A means "not A." In some other contexts, it means

For the function f(x) = x + 4, what is the ordered pair for the point on the graph where x = 3p?

(x, x + 4)
(x, 3p + 4)
(3p, x + 4)
(3p, 3p + 4)

Answers

Answer:  Choice D.   (3p, 3p+4)

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

Work Shown:

f(x) = x+4

y = x+4 ..... since y = f(x)

y = 3p+4 .... replace x with 3p, because x = 3p

(x,y) = (3p, y) .... replace x with 3p

(x,y) = (3p, 3p+4) ... replace y with 3p+4

Answer:

D

Step-by-step explanation:

In an ordered pair, the input is the first value, and the output is the second value.

The input, x, in this case equals 3p, so that will be our first value, which eliminates answers A and B.

Now to find the output, simply plug the input into all instances of x in the equation, like so:

[tex]f(3p) = (3p) + 4 [/tex]

Resolving that, we get 3p + 4 as our second value, which combined with our first value gets us (3p, 3p+4), which is answer D.

The Beach Boys were an influential surf rock band, filled with guitars and harmonies. Their leader, Brian Wilson, rose up as one of the most significant, original musicians and composers of 20th-century popular music. In the early 1960s, Brian formed the band the Beach Boys with his brothers Dennis and Carl, his cousin Mike Love, and their school friend, Al Jardine. He wrote many of the band's songs, launching the group into stardom and celebrating the surf culture's fascination with fun in the sun. He was responsible for such hit songs as Help Me, Rhonda and Surfin' USA. Even though he became deaf in one ear, he continued to arrange and compose most of the Beach Boys' songs, which were flooded with harmonies and interesting chord progressions that weren't normally heard in pop music. Brian Wilson was also admired by the Beatles, though he viewed that band as competition. Wilson was a perfectionist, always wanting his music to be absolutely perfect, which sometimes caused stress in the group. His desire to be perfect led him to become very depressed in the 1970s. He was able to get back up on his feet after receiving counseling, along with the love and support of family and friends. Continuing to write music, he finished projects that were left unfinished and impressed audiences yet again with his unique orchestral songs. In 1988, Brian Wilson overcame difficulties and released a solo album. He also released some music that he had once written for the Beach Boys, but that they never produced. He showed that he hadn't lost his touch as a singer and unbelievably talented songwriter.Which of the following best describes Brian Wilson?A.) He was completely deaf and yet still wrote impressive, harmonious music for audiences.B.) He was an important songwriter and musician in the band the Beatles.C.) He was a member of the band the Beach Boys with his brothers Dennis and Carl.D.)He was very influential in the world of pop music.
