Answer:
[tex]\huge\boxed{\text{96 students}}[/tex]
Step-by-step explanation:
In order to find how many students stay back for Chess Club, we want to find 12% of 800.
To do this, we can set up a percentage proportion.
[tex]\frac{12}{100} = \frac{x}{800}[/tex]
We can now solve for x by cross multiplying.
[tex]800 \cdot 12 = 9600\\9600 \div 100 = 96[/tex]
So, 96 students attend Chess Club on Wednesdays.
Hope this helped!

4y - 7 = 5x2 - x + 2 + 3y
Quadratic Equations
Options are No, One, Two.
I don't remember learning how to do it with more than a, b, and c variable. I'm so confused please help.
Answer:
y = 9 + -1x + 5x2
Step-by-step explanation:
Simplifying
4y + -7 = 5x2 + -1x + 2 + 3y
Reorder the terms:
-7 + 4y = 5x2 + -1x + 2 + 3y
Reorder the terms:
-7 + 4y = 2 + -1x + 5x2 + 3y
Solving
-7 + 4y = 2 + -1x + 5x2 + 3y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-3y' to each side of the equation.
-7 + 4y + -3y = 2 + -1x + 5x2 + 3y + -3y
Combine like terms: 4y + -3y = 1y
-7 + 1y = 2 + -1x + 5x2 + 3y + -3y
Combine like terms: 3y + -3y = 0
-7 + 1y = 2 + -1x + 5x2 + 0
-7 + 1y = 2 + -1x + 5x2
Add '7' to each side of the equation.
-7 + 7 + 1y = 2 + -1x + 7 + 5x2
Combine like terms: -7 + 7 = 0
0 + 1y = 2 + -1x + 7 + 5x2
1y = 2 + -1x + 7 + 5x2
Reorder the terms:
1y = 2 + 7 + -1x + 5x2
Combine like terms: 2 + 7 = 9
1y = 9 + -1x + 5x2
Divide each side by '1'.
y = 9 + -1x + 5x2
Simplifying
y = 9 + -1x + 5x2

Actually Welcome to the Concept of the Trigonometry.
here, we use the Linear pair property of the adjacent angles.
We know that, all the adjacent angles in a linear pair add to get 180°
so we get as,
=> (n+6) +90°+(2n+3) =180°
=> (n+6) +(2n+3) =180-90
=> 3n+9 = 90
=> 3n= 90-9
=> 3n = 81
hence, n = 81/3
=> n = 27°
thus the value of n is 27° .

Diane walks 5 , 000 steps each day for exercise. Over the next year, her goal is to increase the number of steps she walks each day by 10 . Let f ( x ) represent the number of steps Diane plans to walk on day x since beginning her goal. What does f ( 100 ) = 6 , 000 represent? Select from the drop-down menus to correctly complete the sentence. Diane plans to walk steps on day since beginning her goal.
Answer:
Diane plans to walk [6,000] steps on day [100] since beginning her goal.
Step-by-step explanation:
10 x 100 = 1,000
5,000 + 1,000 = 6,000
100 days after adding 10 steps each day results in 6,000 steps

I need some help putting it in ordered pair
Solve each system of equations.
2x- 4y = 20
x=4
Answer:
(x,y)=(4,-3)
Step-by-step explanation:
2x- 4y = 20
x=4
Substitute the value of x
2*4-4y=20
Solve equation
y=-3
A possible solution is
(x,y)=(4,-3)
Check the solution
2*4-4*(-3)=20
4=4
Simplify
20=20
4=4
The ordered pair is the solution
The solution of the given system of equations is y = -3.
What is the equation?A formula known as an equation uses the same sign to denote the equality of two expressions.
In another word, the equation must be constrained with some constraints.
For example 5x + 4y = -8
Given the set of equations,
2x- 4y = 20
x=4
By substitution,
2(4) - 4y = 20
8 - 4y = 20
-4y = 20 - 8
-4y = 12
By multiplying by -1 both sides
4y = -12
By dividing 4 both sides
y = -3
Hence "The solution of the given system of equations is y = -3".

Colleen is selling tubs of popcorn to raise money for the school choir. Her goal is to raise $150. Colleen starts with 40 tubs of popcorn, and she has already sold
3/4 of them. If each tub of popcorn sells for $3.75, how much more money does Colleen need to raise to reach her goal?
Colleen needs to raise $37.5 to reach her goal.
What is the arithmetic operation?In mathematics, the arithmetic operation has four main operators such as addition, subtraction, multiplication, and division.
The symbol of + represents addition.
The symbol of - represents subtraction
The symbol of × represents multiplication
The symbol of ÷ represents division.
The goal of Collen is 40 tubs.
3/4 of 40 = 30 tubs.
Money for 30 tubs
⇒ 30 × 3.75 = $112.5
She needs
$150 - $112.5 = $37.5
Hence " Colleen needs to raise $37.5 to reach her goal".

Select all the pairs that could be reasonable approximations for the diameter and circumference of a circle. * 1 point A. 5 meters and 22 meters. B. 19 inches and 60 inches. C. 33 centimeters and 80 centimeters.
Answer:
B. 19 inches and 60 inches.
Step-by-step explanation:
Required
Select matching pairs
Represent diameter with D and Circumference with C
C is calculated as:
[tex]C = \pi D[/tex]
Where
[tex]\pi = 3.142[/tex]
A. D = 5m; C = 22m
Using: [tex]C = \pi D[/tex]
[tex]C = 3.142 * 5[/tex]
[tex]C = 15.71[/tex]
15.71 does not approximates to 22m.
Hence, the pair do not match
B. D = 19 in; C = 60 in
Using: [tex]C = \pi D[/tex]
[tex]C = 3.142 * 19[/tex]
[tex]C = 59.698[/tex]
59.698 approximates to 60.
Hence, the pair match
C. D = 33 cm; D = 80 cm.
Using: [tex]C = \pi D[/tex]
[tex]C =3.142 * 33[/tex]
[tex]C =103.686[/tex]
103.686 does not approximates to 22m.
Hence, the pair do not match
From the analysis above, only option B matches the diameter with the circumference
