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.

Answer:
answer is A
Step-by-step explanation:
This symbol is called a tilde. In symbolic logic (a field of math
used a lot in computer sciences) it is used to denote "not." For
example, ~A means "not A." In some other contexts, it means
"approximately." For example, pi ~= 3.1416. (Note that sometimes it is
written above the equal sign, and sometimes it is used without an
equal sign - it depends on the situation and the publisher.)

A parrot is selling for 40% off the original
price. The original price was $90. What is the
sale price of the parrot?
Answer:
$54
Step-by-step explanation:
The original price was $90
The sale of the parrot is 40% off
40% * $90 = $36
The sale price = $90 - $36 = $54
Hence, the sale price of the parrot = $54
a bus is traveling at a constant speed . if the the bus travels 15 1/2 miles in 1/3 of an hour , how many miles will the bus travel in one hour?
Answer:
46.5 miles per hour
Step-by-step explanation:
15 1/2 (15.5) miles = 1/3 hour (20 minutes)
15.5 miles x 3 = 46.5 miles per hour

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′?
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)

Five more than a number g is six less than twice a number h. Solve for g.
Answer:
g=2h-11
Step-by-step explanation:
You need to make the two sides equal, so add 6 to the left side:
[tex](g+5)+6=2h[/tex]
Solve for g
[tex]g+5+6=2h\\\\g+11=2h[/tex]
Isolate g
[tex]g=2h-11[/tex]

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.
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 rectangle is enlarged by a factor of 6.
A rectangle with an area of 20 inches squared.
What is the area of the enlarged rectangle?
120 in.²
720 in.²
2,400 in.²
14,400 in.²
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
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)
=============================================
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.
