When f = 2 and g = 8, n = 4. if n varies jointly with f and g, what is the constant of variation? one-fourth one-half 4 64
The value of the constant of variation is one-fourth. Then the correct option is A.
What is the constant of variation?The term "constant of variation" refers to the fact that the relationship between variables remains constant.
The formula will be
y = kx
where k is the variation constant.
When f = 2 and g = 8, n = 4. if n varies jointly with f and g, then the equation will be
n = kgf
Then the value of k will be
4 = (2)(8)k
k = 1/4

Since, the fundraiser only have three prices for books($2, $5 and $10), the number of $5 book that was sold is 12.
How to form equation and solve ?The fundraiser only have 3 prices for books which are $2, $5 and $10.
There were 6 more $5 books sold than $10 books sold.
Let
x = number of $10 book sold
Therefore,
number of $5 books sold = x + 6
There are 8 more $2 book sold than $10 book sold. Therefore,
number of $2 books sold = x + 8
A total of $250 was raised.
Therefore, the total amount sold forms the following equation:
10x + 5(x + 6) + 2(x + 8) = 250
10x + 5x + 30 + 2x + 16 = 250
17x = 250 - 30 - 16
17x = 204
x = 204 / 17
x = 12

Answer:
69.5 if C and D both add up to 90, M=90 if both angles C and D were complementary to combine to a supplementary.
Step-by-step explanation:
You're trying to find m which is a variable for measurement for the "D" angle.
Info Given:
20.5 for angle C
Unknown for angle D
Both angles are Complementary.
_____________________________________________
I have 2 answers for this (The question was stated unclearly so I have 2 interpretations of this)
1st Answer:
If you're asking to solve for M but the C and D angles add up to 90 then do
90 - 20.5 = 69.5
2nd Answer:
We know that both angles are complementary which are 90-degree angles.
If we combine them then the angles add up to 180.
So C and D add up to form a Supplementary Angle.
20.5+69.5 + m = 180
Then M could possibly be 90.

Answer:
IQR = 5
Step-by-step explanation:
the IQR is the difference between the upper quartile Q₃ and the lower quartile Q₁
Q₃ is the value at the right side of the box plot , that is
Q₃ = 51
Q₁ is the value at the left side of the box plot , that is
Q₁ = 46
then
IQR = Q₃ - Q₁ = 51 - 46 = 5

please helP!
Answer: y = -1.3
Step-by-step explanation:
3x-2y=-3,-9x+6y=9 solve each system using elimination, state the solution and type of system.
We will see that the system of equations has infinite solutions, each of the form:
y = (3/2)*(x + 1)
How to solve the system of equations?Here we have the system:
3x - 2y = -3
-9x + 6y = 9
Notice that if we add 3 times the first equation to the second one, we get zero.
3*(3x - 2y) + -9x + 6y = 3*(-3) + 9
9x - 6y - 9x + 6y = -9 + 9
0 = 0
This actually means that both equations represent the same line, then, the "two" lines intersect in infinite points, meaning that the system of equations has infinite solutions, which are of the form:
3x - 2y = -3
2y = 3 + 3x
y = (3/2)*(x + 1)

Write the ratio in simplest form: there are 6 red marbles and 22 blue marbles in a jar. What is the ratio of red marbles to blue?
Answer:
3 : 11Step-by-step explanation:
Given : the ratio of red marbles to blue marbles is 6 to 22
But ,we want to write the ratio in simplest form
therefore ,we have to divide both sides of the ratio by their greatest common factor GCF.
→ So Let’s find the GCF(6 , 22)
Since 6 = 2 × 3
22 = 2 × 11
then ,GCF(6 , 22) = 2
Eventually ,the ratio 6 : 22 in its simplest form I suppose 3 : 11
A quadratic equation of the form 0=ax2 bx c has a discriminant value of -16. how many real number solutions does the equation have?
The given quadratic equation has no real solutions.
Given quadratic equation is:
[tex]ax^2+bx+c=0[/tex]
What does the discriminant of a quadratic equation tell?The discriminant(D) of a quadratic equation tells about the nature of roots.
If [tex]D > 0[/tex], the roots of the quadratic equation will be real and distinct.
If [tex]D=0[/tex], the roots of the quadratic equation will be real and equal.
If [tex]D < 0[/tex], the roots of the quadratic equation will be imaginary.
Given that the quadratic [tex]ax^2+bx+c=0[/tex] has a discriminant value of -16.
[tex]D=-16 < 0[/tex]
So, the roots of the given quadratic equation will be imaginary.
So, the given quadratic equation has zero real solutions.

The value of log(0.5) is -0.30103.
The value of given expression is -4.81648.
If the final answer appromatted to preceding integer, then the correct option is -4.00.Step-by-step explanation:
The value of the [tex]log_{0.5}[/tex] (16) will be -4.00 so the correct option will be (A).
What is a logarithm?The exponent indicates the power to which a base number is raised to produce a given number called a logarithm.
A logarithm is a power to which a number must be raised in order to get some other number.
A logarithm is useful to find out the values on which power has a variable.
In another word, a logarithm is a different way to denote any number.
If you want to write 1 in logarithm then it will be log(base).
[tex]log_{a}[/tex] (x) = b ⇒ [tex]a^{b}[/tex] = x.
Let's say the given number is x then
x = [tex]log_{0.5}[/tex] (16)
[tex]0.5^{x}[/tex] = 16
Take log by both sides
Log[tex]0.5^{x}[/tex] = log 16
By log property
x log 0.5 = log 16
x = -4.00 hence, the correct answer to the given question will be -4.00.
