Answer: 114 red marbles
Step-by-step explanation:
We know that for every 20 marbles, there are 19 red and 1 black marble.
So to get from 20 to 120, we multiply by 6. So we take 19 times 6 = 114 red marbles and 6 black marbles,

The city planner wants to put recycling bins at the circumcenter of the park. What are the coordinates of the recycling bins?.
The coordinates of the recycle bin will be = ( -1, 2.5 )
According to the information given in the question,
The coordinates of the vertices of the park are,
( 1, 1 ), ( 1, 4 ), and ( -3, 4 )
We have to find the coordinates of the recycle bin.
Let us consider the equation of the circle,
[tex]x^{2} +y^{2}+Dx + Ey+ F =0[/tex]
So putting the values of the coordinates into the equation,
First Equation,
[tex]1^{2}+1^{2} + D + E + F = 0[/tex]
Second Equation,
[tex]1^{2} +4^{2} +D + 4E + F=0[/tex]
Third Equation,
[tex](-3)^{2} + 4^{2} - 3D+4E+F=0[/tex]
Subtracting the first equation from the second,
[tex]1^{2} +4^{2} +D + 4E -E=0[/tex]
15 + 3E = 0
3E = -15
E = -5
Subtracting the third equation from the second,
1 + 16 - 9 - 16 + D + 3D = 0
4D = 8
D = 2
Putting the values of E and D in the first equation,
1 + 1 + D + E + F = 0
F = -2 - D - E
F = 1
So now the equation of the circle becomes,
[tex]x^{2} +y^{2}+2x - 5y+ 1 =0[/tex]
By expanding the above equation we can find the standard equation,
[tex]x+2x+1^{2} +y^{2} -5y+ 2.5^{2}- 1^{2} -2.5^{2} +1 =0[/tex]
[tex](x+1)^{2} + (y - 2.5)^{2} = 1^{2} + 2.5^{2} -1[/tex]
[tex](x+1)^{2} + (y - 2.5)^{2} = 2.5^{2}[/tex]
So the required circumcenter will be = ( -1, 2.5 )
Therefore, the coordinates of the recycle bin will be = ( -1, 2.5 )

Exponents:
The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself. For instance, the number 6 is multiplied by itself four times, yielding 6 6 6 6. You can write this as 64.In this case, the exponent is 4 and the base is 6. This can be understood as 4 increased to the power of 6.The symbol used for representing the exponent is ^. This symbol (^) is called a carrot. For example, 4 raised to 2 can be written as 4^2 or 42. Thus, 4^2 = 4 × 4 = 16Adding exponents while maintaining the same base is the rule for multiplying like bases.exponents should be multiplied while bases are kept constant when bases are raised by a power of two or more.Division Rule: When dividing like bases, maintain the base constant and deduct the exponent of the denominator from the exponent of the numerator.To know more about Exponents:

There were 794 fih at 9:00 A. M. The dolphin were fed at 5:00 P. M. There were 209 fih left etimate how many fih the dolphin ate
the number of fih at 9:00 A.M. (794), which yields 209 fih, the number of fih left at 5:00 P.M. is 585 fih
Subtract the number of fih at 9:00 A.M. (794) from the number of fih left at 5:00 P.M. (209).
794 - 209 = 585
Therefore, the dolphin ate 585 fih.
To estimate how many fih the dolphin ate, we must first subtract the number of fih at 9:00 A.M. (794) from the number of fih left at 5:00 P.M. (209). This gives us 585 fih, which is the estimated number of fih that the dolphin ate. This calculation can be verified by subtracting the number of fih the dolphin ate (585) from the number of fih at 9:00 A.M. (794), which yields 209 fih, the number of fih left at 5:00 P.M.

The heights of the starting 5 players (not including the libero) on a volleyball team like karasuno high school are 60 inches, 67 inches, 64 inches, and 65 inches. If the balance point of the players is 65, what is the height of the 5th player?.
The height of the 5th player would be 69 inches
To find the Height, first, we have to calculate the mean value.
No. of players=5
The height of 4 players is 60 inches, 67 inches, and 64 inches, 65 inches.
Mean =Sum of observations/No of observations
Mean of the 5th players=65
To find, Height of 5th player
As we know,
Assuming the height of the 5th player is x
Mean =Sum of observations/No of observations
65=(60+67+64+65+x)/5
65*5=60+67+64+65+x

If a rectangle and a quare have the ame perimeter then which one will have a larger area
The area of the square is bigger than the Area of the rectangle.
Suppose the sum of all the sides in a square is this: 4 x A and the same is true of a rectangle, too.
Then, first, the area of the square is A^2.
And next, assuming that we have this: 0 < X < A and that one side in the rectangle is this: (A - X)
we can say that the side next to (A - X) is this: (A + X) because the sum of all the four sides in the rectangle has to be this: (4 x A), which equals the sum of all the sides in the square.
So now, the area of the square is this: A^2, whereas the area of the rectangle is this: (A^2 - X^2), which equals this: (A + X)(A - X).

An exchange of points from one side of a line with points on the other side of the mirror at the same distance from the mirror occurs when a mirror line is fixed in the plane. There is a mirror line in every reflection. A mirror reflection is followed by a translation that is parallel to the mirror to create a glide reflection.
Here, the shape is mirrored in the reflection. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another.

The size of the standard version is 2.8 megabytes (MB). The size of the high-quality version is 4.3 MB. Yesterday, the high-quality version was downloaded four times as often as the standard version. The total size downloaded for the two versions was 4600 MB. How many downloads of the standard version were there?
Answer:
The number of downloads of the standard version is 230.
Step-by-step explanation:
Let x be the number of downloads of the standard version.
The number of downloads of the high-quality version is 4x.
The total size downloaded for the standard version is 2.8x MB.
The total size downloaded for the high-quality version is 4.3(4x) = 17.2x MB.
The total size downloaded for both versions is 2.8x + 17.2x = 4600 MB.
Combining like terms, we have 20x = 4600 MB.
Dividing both sides by 20, we have x = 230 downloads of the standard version
Two cell phone plans offer differing text packages. The two plans are outlined below: Plan A: $9.25 per month charge along with a charge of $0.06 per text. Plan B: $2.50per month charge, but a charge of $0.20 per text. Is there a certain number of texts, when the two plans cost the same amount? Determine your answer by setting up a system of equations that model the two plans.
Answer:
48
Step-by-step explanation:
Let T be the number of texts sent on each plan.
The cost of Plan A can be represented as $9.25 + $0.06T.
The cost of Plan B can be represented as $2.50 + $0.20T.
We want to find the number of texts T at which the two plans cost the same amount. Therefore, we can set the two equations equal to each other and solve for T:
$9.25 + $0.06T = $2.50 + $0.20T
Subtracting $2.50 from both sides, we get:
$6.75 + $0.06T = $0.20T
Subtracting $0.06T from both sides, we get:
$6.75 = $0.14T
Dividing both sides by $0.14, we get:
T = 48.21
Therefore, the number of texts at which the two plans cost the same amount is approximately 48 texts. This means that if you send fewer than 48 texts per month, Plan A will be cheaper, and if you send more than 48 texts per month, Plan B will be cheaper.

(a) how many 4-permutations are there of a set of six objects? (b) how many 2-permutations are there of a set of nine objects?
There will be a total of 720 4- permutations of a set of six objects. And there will be a total of 72 2- permutations of a set of nine objects.
The calculation for 4-permutations of a set containing six objects
P(6,4)! = 6! / (6-4)1
P(6,4)! = 6×5×4×3x2
P(6,4)! = 720
Therefore, there will be a total of 720 permutations.
The calculation for 2- permutation of a set containing 9 objects
P(9,2)! = (9,7)! = (9-2) = 9! / 7!
P(9,2)! = 9×8x7! / 7!
P(9,2)! = 72
