If it takes about 20 minutes to grade a student paper how long in hours does it take to grade palers for a class of 25 people
Final answer:
It takes about 20 minutes to grade one student's paper, so for a class of 25 students, it would take a total of 500 minutes, which is approximately 8.33 hours to grade all the papers.
Explanation:
If it takes about 20 minutes to grade a student paper, to find out how long it takes to grade papers for a class of 25 students, we need to multiply the number of students by the time taken to grade each paper.
Step-by-Step Calculation:
Multiply the number of students (25) by the minutes per paper (20 minutes): 25 students * 20 minutes per student = 500 minutes.
Convert minutes to hours. Since there are 60 minutes in an hour, we'll divide the total minutes by 60: 500 minutes ÷ 60 minutes per hour = 8.33 hours.
Therefore, it takes approximately 8.33 hours to grade papers for a class of 25 students. Please note that this is an ideal situation without any breaks or interruptions accounted for.

Write a quadratic equation having the given solutions -8
Answer:
[tex]y=x^2+16x+64[/tex]
Step-by-step explanation:
A quadratic needs 2 solutions, but since you only have 1, I am to assume that x = -8 twice (or multiplicity of 2). If x = -8, then in factor form, it's (x + 8). Muliplying that by itself twice:
(x + 8)(x + 8):
[tex]x^2+8x+8x+64=0[/tex]
Simplifying gives you:
[tex]x^2+16x+64=y[/tex]

Answer:
1/2 -2
Step-by-step explanation:
The solution of 2x² + x − 4 = 0 is x = ( -1 ± √33 ) / 2.
What is a Quadratic Equation?A quadratic equation is what can be written in the form of ax²+bx+c=0
The equation is,
2x² + x − 4 = 0
To solve the equation, the equation needs to be factorized.
It can be also solved using the formula for determining roots.
x = ( -b ± √ (b² -4ac)) / 2a
Comparing it with the standard equation ax²+bx+c=0.
a = 2, b = 1, c = -4
Substituting the values
x = ( -1 ± √ (1² -4*2*-4)) / 2 * 2
x = ( -1 ± √ (1 + 32)) / 2 * 2
x = ( -1 ± √33 ) / 2
The solution of the given quadratic equation is x = ( -1 ± √33 ) / 2.

To find the volume of a volleyball with a radius of 11.4 cm, we plug the radius into the formula for the volume of a sphere, V=4/3(pi)(r^3), resulting in an approximate volume of 6185.7 cubic centimeters.
Explanation:The question asks to evaluate the volume of a sphere using the given formula, which is V=4/3(pi)(r^3), where V represents the volume and r is the radius of the sphere. To find the volume of a volleyball with a radius of 11.4 cm, we substitute r with 11.4 in the formula and calculate the volume accordingly.
The calculation would be:
V = 4/3 × pi × (11.4 cm)^3
V = 4/3 × 3.14159 × 11.4 cm × 11.4 cm × 11.4 cm
V = 4/3 × 3.14159 × 1481.784 cm^3
V ≈ 4/3 × 3.14159 × 1481.784 cm^3
V ≈ 6185.7 cm^3
Therefore, the volume of the volleyball is approximately 6185.7 cubic centimeters.

Suppose you choose a marble from a bag containing 3 red marbles, 3 white marbles, and 5 blue marbles. You return the first marble to the bag and then choose again. Find P(red then blue).
The probability of first picks the red and then blue will be,15/121.
What is probability?The chances of an event occurring are defined by probability. Probability has several uses in games, in business to create probability-based forecasts,
No of red marbles =3
No of white marbles = 3
No of blue marbles =5
Total no of the marble is;

Let f(x) = x2 and g(x) = x − 3. Evaluate (f ∘ g)(−2).
Answer: f (g (-2)) = 25
Step-by-step explanation:
Hi, to evaluate (f ∘ g)(−2). Where:
f(x) = x2
g(x) = x − 3
As (f ∘ g)(−2) = f (g (-2))
First we find the value of g (-2) replacing the variable x by the number -2.
g (-2) =-2-3 = -5
Finally , for f(x) = x²,we replace the variable x for the value obtained (-5)
f (g (-2)) = (-5)²= 25

Line AC is tangent to circle O at point C
What is the measure of OAC?
The measure of m<OAC is 45degrees
Tangent line to a circleFrom the given diagram, we can see that the line A is tangential to the circle at point C, hence m<C = 90 degrees
Taking the sum of angle in a triangle
m<OAC + 45 + 90 = 180
m<OAC = 180 - 135
m<OAC = 45 degrees
Hence the measure of m<OAC is 45degrees

What is the solution of the following system? -3x-2y=-12 9x+6y=-9
Answer:
No solution.
Step-by-step explanation:
Use elimination.
Multiply the equation by the opposite equation's x coefficient.
9(-3x - 2y = -12) = -27x - 18y = -108
Again, multiply by the other x coefficient.
-3(9x + 6y = -9) = -27x - 18y = 27
Add the second equation to the first.
-27x - 18y = -108
+27x + 18y = -27 The x and y will cancel each other out.
0 ≠ 135. Since 0 does not equal 135, there is no solution.
Elimination gives an equation that is always false. The two equations in the system represent parallel lines. This is an inconsistent system. It has no solutions.

You have $9, one of your friends has $10, and two of your other friends each have $13. you combine your money to buy arcade tokens. you use a coupon to buy 8 tokens for $1. the cost of the remaining tokens is four for $1. you and your friends share the tokens evenly. how many tokens does each person get? each person gets 65 tokens.
The required number of tokens distributed in each of them is 46 tokens.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Total money = 9 + 10 + 13 + 13 = $45
Total number of persons = 4
For the first $1 there are 8 token
And after that cost of 4 tokens is $1,
Total tokens = 8×1 + 4×(45 - 1)
Total tokens = 8 + 176
Total tokens = 184
Now,
Distribution among the fours,
= 184 / 4
= 46 tokens
Thus, the required number of tokens distributed in each of them is 46 tokens.
