D. 0 = 2x2 – 3x + 1
BRAINLIEST?
Answer:
The correct option is: A. [tex]0=x^2+3x+2[/tex]
Step-by-step explanation:
Quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
After substituting the values of a, b and c into the formula, Ramiya's equation is: [tex]x=\frac{-3\pm\sqrt{3^2-4(1)(2)}}{2(1)}[/tex]
Comparing the above equation with the quadratic formula, we will get........
[tex]2a= 2(1)\\ a=1\\ \\ -b=-3\\ b=3\\ \\ 4ac=4(1)(2)\\ 4(1)c=4(1)(2)\\ c=2[/tex]
The standard form of any quadratic equation is: [tex]ax^2+bx+c=0[/tex]
So, Ramiya’s quadratic equation will be: [tex]1x^2+3x+2=0[/tex] or, [tex]0=x^2+3x+2[/tex]
The Ramya's quadratic equation is 0 = x^2 + 3x + 2 option (A) is correct.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
The quadratic formula is:
[tex]\rm x=\frac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]
Ramiya equation is:
[tex]\rm x=\frac{-3\pm \sqrt{3^2-4(1)(2)} }{2(1)}[/tex]
Comparing the Ramiya equation to the quadratic formula, we get:
-b = -3 ⇒ b = 3
2a = 2(1) ⇒ a = 1
4ac = 4(1)(2) ⇒ c = 2
Put these values in the standard equation, we get:
[tex]\rm x^2+3x+2=0[/tex] or
[tex]0=\rm x^2+3x+2[/tex]
Thus, the Ramya's quadratic equation is 0 = x^2 + 3x + 2 option (A) is correct.

Steven wants to buy a $580 bicycle. Steven has no money saved, but will be able to deposit $30 into a savings account when he receives his paycheck each Friday. However, before Steven can buy the bike, he must give his sister $80 that he owes her. For how many weeks will Steven need to deposit money into his savings account before he can pay back his sister and buy the bike?
$30 + $30 = $60
$60 + $30 = $90
To pay back his sister the $80 he will to deposit money into his account for 3 weeks.
Since Steven would have $10 left over in his account from paying his sister all he needs now is $570.
You need to divide:
$570/$30 = 19
So Steven will need to deposit $30 into his bank account for 19 weeks to be able to buy the $580 bicycle.

D=c-s/n solve for c
D = c-s/n
Dn = n(c-s/n)
Dn = c - s
Dn + s = c
c = Dn +s
To solve for c in the equation D=c-s/n, isolate c by multiplying both sides by n, then rearrange the terms and divide by (n-D).
Explanation:To solve for c in the equation D=c-s/n, we need to isolate c. We can start by multiplying both sides of the equation by n to eliminate the fraction:
nD=cn-(s/n)(n)
Simplifying further, we get:
nD=cn-s
Next, we can bring the term cn to the left side of the equation by subtracting cn from both sides:
nD-cn=-(cn-s)
Rearranging the terms, we have:
-cn+nD=-(cn-s)
Factoring out c from the left side, we get:
c(n-D)=cn-s
Finally, we can solve for c by dividing both sides of the equation by (n-D):
c=(cn-s)/(n-D)

A catering company is setting up for a wedding they expect 150 people to attend they can provide tables that seat 6 people and large tables that seats 10 people Is the point (20,5) a solution to the equation 6x+10y=150 explain the point (20,5) means in context
Answer:
(20,5) is NOT a solution of the equation [tex]6x+10y=150[/tex].
The point (20,5) implies that there are 20 small tables and 5 large tables.
Step-by-step explanation:
We have been given that a catering company is expecting 150 people to attend the wedding. There are two types of tables, ones which can fit 6 people and ones which can fit 10 people.
If there are x tables which can fit 6 people and there are y tables which can fit 10 people, we can express the total number of people that can fit on all available tables as: [tex]6x+10y[/tex].
Since there are total 150 people expected in the wedding, the equation can be framed as: [tex]6x+10y=150[/tex].
Let us check if the point (20,5) is a solution of the equation.
[tex]6*20+10*5=150[/tex]
[tex]120+50=150[/tex]
[tex]170=150[/tex]
Since we get a false statement, therefore, (20,5) is NOT a solution of the equation [tex]6x+10y=150[/tex].
The point (20,5) implies that there are 20 small tables and 5 large tables.
To determine if a point is a solution to an equation, substitute the values into the equation. The point (20,5) in the context of a catering company setting up tables represents 20 tables of 6 seats and 5 tables of 10 seats. However, this point is not a solution to the equation 6x + 10y = 150 because substituting these values does not make the equation true.
The point (20,5) in the context of this question represents the numbers of 6-seat and 10-seat tables the catering company needs to set up. To determine if the point (20,5) is a solution to the equation 6x+10y=150, you can substitute the first value of the ordered pair into the equation for x, and the second value for y.
If 6(20) + 10(5) equals 150, then (20,5) is a solution to the equation. Let's check: 6(20) = 120 and 10(5)=50, if you add these results, 120 + 50 you get 170, not 150. So, the point (20,5) is not a solution to the equation because when these values are substituted into the equation, they do not satisfy it (they do not make it true).https://brainly.com/question/29775795

a company makes 2,500 profit on the sale of 20 products, what is the profit when the company sells 300 products
$37,500 profit
To solve this, find the unit rate by dividing 2500 by 20. This will get you an average of $125 profit made per product sold. Then multiply that by 300 (the number of products sold in total) to get your answer of $37,500 profit total.
Answer:
Assuming that the profit is the same for each sale, the amount they make is 37,500
Step-by-step explanation:
In order to find this, we set up a proportion using those numbers.
2500/20 = x/300 ----> Cross multiply
20*x = 2500*300 ----> Multiply
20x = 750,000 ----> Divide by 20
x = 37,500

The ball starts on the ground and travels in a parabolic shape as it reaches a maximum height and then returns to the ground . Suppose further that the ball reaches its maximum height of 15 feet in 2.2 seconds .
the ball reaches its maximum height of 15 feet in 2.2 seconds .
The ball takes 2.2 seconds to reach the maximum height from the ground
Ball takes another 2.2 seconds to reach the ground from the maximum height
So 2.2+ 2.2 = 4.4 seconds
The ball will be in the air for 4.4 seconds

A carpenter has two lengths of wood; one is 108cm long and the other is 72cm long. He wants to cut them up to produce smaller pieces of wood to build a shelving unit so they all need to be the same length, with no wood left over. What is the greatest length, in cm, that he can make the shelves?
Answer:
36 centimeters.
Step-by-step explanation:
1. To solve this problem you must find the Greatest common factor.
2. List the prime factor of 108 and 72:
[tex]108:(2)(2)(3)(3)(3)=(2^{2})(3^{3})\\ 72:(2)(2)(2)(3)(3)=(2^{3})(3^{2})[/tex]
3. Now, you must choose the common prime numbers with the lowest exponents and multiply them:
[tex](2^{2})(3^{2})=(4)(9)=36[/tex]
Answer: He needs 36 cm to make the shelves.
Step-by-step explanation:
Since we have given that
Length of first wood = 108 cm
Length of second wood = 72 cm
We need to find the greatest length so that he can make the shelves.
Greatest length = h.c.f. of 108 and 72 { 36 cm.
Hence, he needs 36 cm to make the shelves.

a birthday party is being fun for 20 people at an arcade it cost $5 a person to provide food for everyone and each game cost $1 per play. assume that each person at the party plays the same number of games,x
First, let's calculate the total cost for food. We know that we have 20 people to feed, and it costs $5 to provide food for each person. Therefore, we multiply the number of people by the cost per person to get the total cost for food. That would be:
20 people * $5/person = $100
So, the total cost for food is $100.
Next, let's calculate the total cost for the games. We're assuming that each person is playing x number of games, and that each game costs $1 to play. Therefore, we multiply the number of people by the cost per game and the number of games each person plays to find the total cost for games:
20 people * $1/game * x games = $20x
So, the total cost for the games depends on the number of games that each person plays.
If we want to find out the total cost of the party, we need to add the total cost for food and the total cost for games. This can be represented as:
$100 + $20x
This means the total cost of the party will be $100 plus $20 times the number of games each person plays. The exact total cost will depend on the value of x, i.e., the number of games each person plays.

Students made 7 art posters that were hung along a hallway that is 4.4 m long. The posters are 0.2 m apart and the first and last posters are 0.2 m from the ends of the hallway. How many meters wide was each poster?
To answer this question, we pose the problem as follows:
It is known that there are 7 posters and between them there is 0.2 meters of separation, we also know that between the beginning of the corridor and the first poster of 0.2 meters, and between the last poster and the end of the corridor there is 0.2 meters from separation . That is, there is a total of 8 separations of 0.2 meters in the corridor.
This is the real length of the corridor occupied by the posters.

What total length of ribbon is needed to Line the two long sides of the hat?
Answer:
Total length of ribbon to line the long sides will be 22 in
Step-by-step explanation:
In the given figure of kite if we draw a line "h" vertically will form two right angle triangles.
Then by applying Pythagoras theorem in both the triangles.
h²= (3x + 5)² + (2x + 1)² ------(1)
h²= (5x + 1)² + 5² ------(2)
By equating both the equations
(3x + 5)² + (2x + 1)² = (5x + 1)² + 25
9x² + 25 + 30x + 4x² + 4x + 1 = 25x² + 10x + 1 + 25
13x² + 34x + 26 = 25x² + 10x + 26
13x² - 25x² + 34x - 10x + 26 - 26 = 0
- 12x² + 24x = 0
12x² - 24x = 0
x² - 2x = 0
x(x - 2) = 0
x = 2
Now we will put x = 2 in the measure of sides of the kite.
Side 1 = (3x + 5)
= 3×2 + 5
= 11
Side 2 = (5x + 1)
= 5×2 + 1
= 11
Side 3 = (2x + 1)
= 2×2 + 1
= 5
Therefore, Total length of ribbon to line the long sides will be = 11 + 11
= 22 in.
Your answer will be D-22.
