Answer:
B
Step-by-step explanation:
The percent of the books that are fiction is 86% and the percent equation is 4300=m×5000. Therefore, option B is the correct answer.
Given that, there are 5,000 books in the town's library.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Let the percent of the books that are fiction be m
So, m= 4300/5000
4300=m×5000
Percentage =4300/5000 ×100
= 86%
The percent of the books that are fiction is 86% and the percent equation is 4300=m×5000. Therefore, option B is the correct answer.

14) zeroes of the polynomial x^2+5x+6 are...
Both positive
Both negative
One is positive and other is negative
None
Answer:
both negative
Step-by-step explanation:
Descartes rule of signs tells us how many positive and negative real roots a polynomial has.
Given
f(x) = x² + 5x + 6 , with signs
+, +, + ← no change of signs, thus no positive zeros
f(- x) = (- x)² + 5(- x) + 6 = x² - 5x + 6 , with signs
+, -, + ← with 2 changes of signs. thus 2 negative zeros
Answer:
B) Both Negative

In the complex plane, the rectangular coordinates (x, y) represent a complex number. Which statement explains why polar coordinates (r, θ) represent the same complex number?
Answer: second option (counting from the top)
Step-by-step explanation:
When we have a number:
z = x + y*i
we can represent this with the point:
(x, y).
Now, remember that in polar coordinates, we need to use the variables:
r = distance to the (0, 0), or the "magnitude" of the point.
θ = angle measured counterclockwise from the x-axis.
r is easy to find, is the magnitude, this is calculated as:
r = √(x^2 + y^2)
To find θ, suppose that we have a triangle rectangle, where x is the adjacent cathetus, and y is the opposite cathetus, and θ is the angle as we described it.
We know that:
Tan(θ) = opposite cathetus/adjacent cathetus = y/x
Tan(θ) = y/x
Then:
θ = Tan^-1 (y/x)
Then the correct option is the second option (counting from the top)

After buying a pair of sneakers, Ben has $12 left which is 20% of what he started with. How much money did Ben have before he bought his pair of sneakers?
Answer: $60
Step-by-step explanation:
Given that:
Amount left after purchasing sneakers = $12
$12 is equivalent to 20% of the initial starting amount
Let starting amount = x
20% of x = $12
0.2x = $12
Divide through by 0.2
0.2x / 0.2 = $12 / 0.2
x = $60
Hence, starting amount before buying sneakers is $60

Two similar triangles are shown on the coordinate grid:
Which set of transformations has been performed on triangle ABC to form triangle A′B′C′?
dilation by a scale factor of 4 followed by reflection about the x-axis
dilation by a scale factor of 2 followed by reflection about the x-axis
dilation by a scale factor of 4 followed by reflection about the y-axis
dilation by a scale factor of 2 followed by reflection about the y-axis
Answer:
The set of transformations has been performed on triangle ABC is dilation by a scale factor of 2 followed by reflection about the x-axis
Step-by-step explanation:
Let us write the vertices of Δ ABC
∵ Vertex A = (-2, -1)
∵ Vertex B = (0, 0)
∵ Vertex C = (1, -3)
Let us Write the vertices of Δ A'B'C'
∵ Vertex A' = (-4, 2)
∵ Vertex B' = (0, 0)
∵ Vertex C' = (2, 6)
Let us find the scale factor k between the x-coordinates of the points and their images.
∵ -4 = k (-2) ⇒ Divide both side by -2
∵ [tex]\frac{-4}{-2}[/tex] = [tex]\frac{-2k}{-2}[/tex]
∴ 2 = k
∴ The scale factor of a dilation is 2
∵ The signs of the y-coordinates of the images are the opposite of
the signs of the y-coordinates of the points
∴ The triangle is reflected about the x-axis
∴ The set of transformations has been performed on triangle ABC
is dilation by a scale factor of 2 followed by reflection about the x-axis

The surface area in square units of a cylinder with a volume of 18 cubic units is a function of its radius in units where . What is the surface area of a cylinder with a volume of 18 cubic units and a radius of 3 units
Answer:
the height is 0.6367 so the surface area is 68.55
Surface area is the total area of an object's outer facing surfaces. The total surface area is calculated by adding all the areas on the surface: the areas of the object's base, top, and lateral surfaces (sides).
How to Find surface area of cylinder?You can use r2 to replace B (area of the base), which is a type of prism with a circular base, and 2r to replace p. (perimeter of the base). The surface area of a cylinder is calculated as SA=2r2+2rh.
Therefore,
The cylinder's surface area is 264 cm2 (approximately)
3 unit is the cylinder's radius.
The cylinder's height is 18 units
To locate:
Area of contact
Having said that,
Cylinder surface area = 2r(h + r)
replacing the necessary values,
Surface area is equal to
2 x 22 /7 x 3 × 3( Plus 4)
Surface area equals 264/7 (7)
Surface area equals 1848/7
264 cm2 is the surface area.
The cylinder's surface area is 264 cm2 (about).

The slope is [tex]\frac{dy}{dx}[/tex] which means it's 100/40 which is 2.5 or 5/2
[tex]d[/tex] has a full time job in defining difference :D
So basically the slope is defined as the difference in the [tex]y[/tex] over the difference in the [tex]x[/tex]
Answer:
5/2
Step-by-step explanation:
To find slope, we can see how much to rise and run from one point to another. In this example, the slope would be 5/2 because you rise 5 and run 2 to get to a different point.

Answer:
5.35*2+x=16 and the answer is $.35
Step-by-step explanation:
5.35*2+x=16
10.70+x=16
-10.70 -10.70
x=5.30
5.30/15= about .35
Answer
$12.65/15

write the equation of a line that is perpendicular to the line y=-3/7-15 and that passes through the point (9,2)
Answer:
Step-by-step explanation:
First substitue the coordinates to the equation so
x=9, y=2
you would get
2=-3/7(9) + b
we put b because we are trying to find the new slope
multiply the two numbers above
2=-3/6/7 + b
subtract the whole number from both sides
b= 5/6/7
in equation would be
y= -3/7 + 5/6/7

Answer:
8.75 or 8 3/4
Step-by-step explanation:7
The numbers in 7 divided by 4/5 are labeled below:
7 = whole number
4 = numerator
5 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
7 x 5
4
=
35
4
Thus, the answer to 7 divided by 4/5 in fraction form is:
35
4
To make the answer to 7 divided by 4/5 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
35 / 4 = 8.75
The answer is rounded to the nearest two decimal points if necessary.
35/4 is an improper fraction and should be written as 8 3/4.

There are 4 boys and 2 girls from the seventh grade and 3 boys and 5 girls from the eighth grade in the math club. The math club sponsor will randomly pick one student from each grade level to represent the team.
What is the probability that both will be girls?
Answer:
5/24 or 20.8%
Step-by-step explanation:
Probability that the 7th grader is a boy = number of boys/(total kids) = 4/(4+4) = 1/2
Probability that the 8th grader is a boy = 5/(5+7) = 5/12
Probability that both are boys = 1/2*(5/12) = 5/24 or 20.8%
