Answer:
The circumfrence is 150pi.
Step-by-step explanation:
While a circle, symbolically, represents many different things to many different groups of people including concepts such as eternity, timelessness, and totality, a circle by definition is a simple closed shape. It is a set of all points in a plane that are equidistant from a given point, called the center. It can also be defined as a curve traced by a point where the distance from a given point remains constant as the point moves. The distance between any point of a circle and the center of a circle is called its radius, while the diameter of a circle is defined as the largest distance between any two points on a circle. Essentially, the diameter is twice the radius, as the largest distance between two points on a circle has to be a line segment through the center of a circle. The circumference of a circle can be defined as the distance around the circle, or the length of a circuit along the circle. All of these values are related through the mathematical constant π, or pi, which is the ratio of a circle's circumference to its diameter, and is approximately 3.14159. π is an irrational number meaning that it cannot be expressed exactly as a fraction (though it is often approximated as 22/7) and its decimal representation never ends or has a permanent repeating pattern. It is also a transcendental number, meaning that it is not the root of any non-zero, polynomial that has rational coefficients. Interestingly, the proof by Ferdinand von Lindemann in 1880 that π is transcendental finally put an end to the millennia-old quest that began with ancient geometers of "squaring the circle." This involved attempting to construct a square with the same area as a given circle within a finite number of steps, only using a compass and straightedge. While it is now known that this is impossible, and imagining the ardent efforts of flustered ancient geometers attempting the impossible by candlelight might evoke a ludicrous image, it is important to remember that it is thanks to people like these that so many mathematical concepts are well defined today.
5y + 32 = -64 find the value of y
Answer:
[tex]y = 19 \frac{1}{6} [/tex]
Step-by-step explanation:
[tex]5y + 32 = - 64 \\ 5y = - 64 - 32 \\ 5y = 96 \\ \frac{5y}{5} = \frac{96}{5} \\ y = 19 \frac{1}{6} [/tex]

~Hi1315~
An adult takes 400 mg of ibuprofen. Two hours later, there is 201.6 mg of
ibuprofen left in the persons system. How long will it take until there is only 25 mg
of ibuprofen left in the person's system? Show all work and round your answer to
three decimal places.
Answer:
It will take 3 hours 46 minutes and 8 seconds to use 375 mg of ibrufen.
Step-by-step explanation:
An adult takes 400 mg of ibuprofen. Two hours later, there is 201.6 mg of
ibuprofen left in the persons system
This means that in 2 hours time
400- 201.6= 198.4 mg was used up.
We need only 25 mg in the system
so 400- 25= 375 mg time is needed
time mg
2 hour 198.4
x 375
Using the cross product rule
x= 375*2/198.4
x= 3.780 hrs
Which means 3 hours and (0.78* 60)= 46.8 minutes.
It will take 3 hours 46 minutes and 8 seconds to use 375 mg of ibrufen.

how much paper is needed to cover a rectangular bulliten board that is 29 in. wide and 37 in. high?
Answer:
1073 inches squared.
Step-by-step explanation:
To find how much paper is needed to cover the board, you have to find the area. The formula of area for rectangles is length times width or as you said in the question width times height.
To find the answer:
Area = length * width
Area = 29 * 37
Area = 1073 inches squared.

Find the area of the figure above.
[?] cm2
Answer:
We first ALWAYS have to split the figure apart from each other,
lets split it into a triangle and a square!
Let's find the area of the triangle:
20(height) x 20(base) = 400!
400 x 1/2 (just dividing by 2) = 200!
*Remember* Formula of a triangle is:
B(base) x H(height) x 1/2 (basically dividing by 2)
Now time to find the area of the square!
20 x 20 = 400!
Now let's add both their areas:
400 + 200 = 600!
Step-by-step explanation:
600cm2 is your answer.
The figure has an area of 600 square centimeters.
In this question we need to determine the area of the entire figure, this area is the sum of the areas of a square and two symmetric right triangles, defined by respective formulas, that is:
[tex]A = A_{s} + 2\cdot A_{t}[/tex] (1)
Where:
[tex]A[/tex] - Total area, in square centimeters.[tex]A_{s}[/tex] - Square area, in square centimeters.[tex]A_{t}[/tex] - Triangle area, in square centimeters.By applying area formulas for squares and triangles, we expand (1):
[tex]A = x^{2} + \frac{1}{2}\cdot x\cdot y[/tex] (2)
Where:
[tex]x[/tex] - Side length of the square, in centimeters.[tex]y[/tex] - Height of the two right triangles, in centimeters.If we know that [tex]x = 20\,cm[/tex] and [tex]y = 20\,cm[/tex], then the area of the figure is:
[tex]A = \frac{3}{2}\cdot (20\,cm)^{2}[/tex]
[tex]A = 600\,cm^{2}[/tex]
The figure has an area of 600 square centimeters.

Write the polynomial in standard form then name the polynomal based on its degree and number of terms 2-11x2-8x + 6x2
Write the polynomial in standard form then name the polynomal based on its degree and number of terms 2-11x²-8x + 6x²
Answer:
Standard form: -5x²- 8x + 2
name: Quadratic polynomial
Step-by-step explanation:Given polynomial
2-11x²-8x + 6x²
To write this polynomial in standard form,
i. First simplify it
Collect like terms
2 - 11x² + 6x² - 8x
Add the second and fourth terms
2 - 5x² - 8x
ii. Arrange the terms in the polynomial in order of decreasing order of x.
In other words, the term which has the highest order of x is written first followed by the term with the next highest order of x and so on.
In this case, the term with the highest order of x is the second term which is given by -5x² followed by -8x and then 2.
Therefore, the standard form of the given polynomial is
-5x²- 8x + 2
The degree of a polynomial which is in standard form is the order of its first term.
In this case, the order of the first term is 2. This means that the degree of the polynomial is 2.
Since the degree of the polynomial is 2 and it has three terms, this is a quadratic polynomial.

The graph below represents slope as a rate of change
Which is the slope of the line shown?
A. 4.8
B. -3
C. -2/3
D. 2/3
Answer:
D. 2/3
Step-by-step explanation:
Two distint points on the graph are
(0, -3) and (6, 1)
Slope = (rise in y) / (run in x)
Rise:
y goes from -3 to 1
rise = 4
Run
x goes from 0 to 6
run = 6
Slope = 4/6

BM 1: 2. Find the value of angles x and y in circle A.
.X=
150°
175°
y =
to
Answer:
x = 35
y = 17.5
Step-by-step explanation:
By Central angle and its corresponding arc theorem:
x° = 360° - (175° + 150°)
x° = 360° - 325°
x° = 35°
x = 35
By inscribed angle theorem:
[tex]y \degree = \frac{1}{2} x \\ \\ y\degree = \frac{1}{2} \times 35 \degree \\ \\ y\degree = 17.5 \degree \\ \\ y \: = 17.5[/tex]
Answer:
x=35 y=17.5
Step-by-step explanation:
This problem wants you to find the angles of an inscribed and central angle.
Note: central angles are angles that have radii as there sides and the center (of the circle) as its center. Inscribed angles are angles that have chords as there sides and there vertex as a point on a circle.
I will by find the measure of the missing arc. To do this is simple, Just add 175+150 and subtract from 360,
175+150= 325
360-325=35
So, the missing arc length is 35. X is a central angle and central angles are equal to the arc length. This means that,
x=35
Lastly, we need to find y, an inscribed angle. Inscribed angles are half of the arc length. So, the measure of y is 17.5
y=17.5

Can some one help on number 5 and 6 please
Step-by-step explanation:
To find mean-
you add all the #'s together and then (/) them by the amount of the #'s
#5. 8, 2, 3, 5, 7
8+2+3+5+7
10+8+7
10+15
25
25/ 5
5
#6. 4, 1, 6, 3, 6, 4
4+1+6+3+6+4
5+9+10
5+19
24
24/ 6
4
The median is the (middle) you have to put the #'s in order least to greatest
#5. 2, 3, 5, 7, 8
cross one by one on both sides
3, 5, 7,
5
#6. 1, 3, 4, 4, 6, 6
3,4,4,6
4,4
4 (because in the middle of 4 and 4 well is 4) (if you had 5 and 6 left it would be 5.5)
The mode is the # that appear the most often in the set of data.
#5. there is no more because there is one of each # there is none that has 2 or more (N/A)
#6. 1,3, 4, 4, 6, 6
the mode is 4 and 6
because those #'s have 2 or more and they are both at 2 so they are both the mode
