Answer:
A) x+4y=13
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(2-4)/(5-(-3))
m=-2/(5+3)
m=-2/8
simplify
m=-1/4
y-y1=m(x-x1)
y-4=-1/4(x-(-3))
y-4=-1/4(x+3)
y=-1/4x-3/4+4
y=-1/4x-3/4+16/4
y=-1/4x+13/4
y-(-1/4x)=13/4
y+1/4x=13/4
4(y+1/4x)=4(13/4)
4y+4/4x=13
4y+x=13
x+4y=13

Here, we will apply the concept of Vertically Opposite angle property and central angle property ;
So here, as b is vertically opposite to the angle whose measure is 20° . So , b will also be 20°
And, if we see the angle c, so angle vertically opposite to c will also be c, and as central angle is of 360° , so ;
[tex]{:\implies \quad \sf c+c+20^{\circ}+20^{\circ}=360^{\circ}}[/tex]

Input for x on first input is 7! 2*7+4
Input for x on second input is 9 2*9+4
Input for x on third input is 15 2*15+4
Hope this helps!
Answer:
(7, 18) (9, 22) (15, 34)
Step-by-step explanation:
so all you have to do is substitute the values given
substitute the input into x
wait a minute.. its output so what you ACTUALLY have to do is
18 = 2x + 4
then solve for the inputs
14 = 2x
x = 7
22 = 2x + 4
18 = 2x
x = 9
34 = 2x + 4
30 = 2x
x = 15
How do you think you could find the volume of a cylinder
Answer:
to find the volume of a cylinder formulae is pi r² x Height
Step-by-step explanation:
because to find the volume of any object we have to multiply the area of the base and the height
now as the base of the cylinder is circle we have to fulfill the area of circle with the height of the cylinder
hence
volume
of
the
cylinder = area of circle x height
= pi r² x Height

What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, that Mia took a taxi from her house to the airport.
The taxi company charged a pick-up fee of $1.30 plus $4.25 per mile. The total fare was $31.05.
∴ Her taxi charge excluding the pickup fee is,
= (31.05 - 1.30) dollars.
= 29.75 dollars.
So, the no. of miles she rides is,
= (29.75/4.25) dollars.
= 7 miles.

A recipe requires 4.5 teaspoons of sugar to make a cup of pudding. Which equation shows the number of teaspoons of sugar, y, needed to make x cups of pudding?
x = 4.5y
y = 4.5 + x
y = 4.5x
x = 4.5 + y
I am in middle school, I just clicked the wrong button.
Answer:
x = 4.5y
Step-by-step explanation:
x = pudding
y = teaspoons
y = 1 so 1 x 4.5 will get you 4.5 teaspoons of sugar

What is the discriminant of -2x2 - x-1=0
Answer:
-7
Step-by-step explanation:
In the equation of ax² +bx +c= 0, the discriminant (denoted by D) is [tex]\textcolor{steelblue}{b^{2} - 4ac }[/tex].
-2x² -x -1= 0
Let's identify the values of a, b and c in this equation! It is important to account for the negative sign too.
a= -2, b= -1, c= -1
D
= (-1)² -4(-2)(-1)
= 1 -4(2)
= 1 -8
= -7
Implications of discriminant
The discriminant tells us the number of roots (solutions) the equation hasWhen D < 0, there are no real rootsWhen D= 0, there is one real rootWhen D > 0, there are two real rootsFind the approximate Volume of a Sphere with a diameter of 10.

In this part we will just focus on Semicircle with diameter 22 ft.
Given :-
Diameter = 22 ft[tex] \\ [/tex]
To find:-
Area of semicircle[tex] \\ [/tex]
So first of all let's convert diameter into radius.
we know:-
[tex] \boxed{ \rm{}radius = \frac{Diameter}{2} }[/tex]
So:-
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = \dfrac{Diameter}{2} [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = \dfrac{22}{2} [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = \dfrac{2 \times 11}{2} [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = \dfrac{\cancel2 \times 11}{\cancel2} [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = \dfrac{11}{1} [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = 11[/tex]
[tex] \\ \\ [/tex]
Now let's find area of semicircle!
We know:-
[tex] \boxed{ \rm Area~of~semicircle = \frac{\pi {r}^{2} }{2} }[/tex]
[tex] \\ [/tex]
so:-
[tex] \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _1= \dfrac{\pi {r}^{2} }{2} [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _1= \dfrac{22 \times {11}^{2} }{7 \times 2} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _1= \dfrac{\cancel{22} \times {11}^{\cancel2} }{7 \times \cancel2} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _1= \dfrac{11\times {11}^{\cancel2} }{7} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _1= \dfrac{1331}{7} \\ [/tex]

[tex] \dashrightarrow\bf Area~of~semicircle _1= 190.14 \\ [/tex]

[tex] \gray{ \bf \dag \frak{Part 2}}[/tex]
So in this part we will find area of other semicircle.
Now as u can see BC isn't given , but AC and AB are given.
So let's find BC:-
AC = AB + BCBC = AC - ABBC = 30 - 22BC = 8 ft[tex] \\ [/tex]
Now we got the diameter, so let's change it into radius.
we know:-
[tex] \boxed{ \rm{}radius = \frac{Diameter}{2} }[/tex]
[tex] \\ [/tex]
so :-
[tex] \hookrightarrow\sf{}radius = \dfrac{Diameter}{2} [/tex]
[tex] \\[/tex]
[tex] \hookrightarrow\sf{}radius = \dfrac{8}{2} [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = \dfrac{2 \times 4}{2} [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = \dfrac{\cancel2 \times 4}{\cancel2} [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow\sf{}radius = 4[/tex]
[tex] \\ [/tex]
Now let's find area of semicircle!
We know:-
[tex] \boxed{ \rm Area~of~semicircle = \frac{\pi {r}^{2} }{2} }[/tex]
[tex] \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{\pi {r}^{2} }{2} [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{22 \times {4}^{2} }{7 \times 2} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{\cancel{22} \times {4}^{\cancel2} }{7 \times \cancel2} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{11\times {4}^{2} }{7} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{11\times 16}{7} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{176}{7} \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow\bf Area~of~semicircle _2= 25.14 \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \gray{ \bf \dag \frak{Part 3}}[/tex]
Now Finally in this part we'll add both the areas of these semicircles.
Let :-
Area of semicircle with diameter AB be A₁Area of semicircle with diameter BC be A₂[tex] \\ \\ [/tex]
[tex] \sf: \implies Area~of~figure=A_1+A_2 \\ [/tex]
[tex] \\ \\ [/tex]
[tex] \sf: \implies Area~of~figure=190.14+25.14 \\ [/tex]

What is the median value of the data set shown on the line plot?
Solution:
Step-1: Find the data.
70's: 180's: 190's: 2100's: 3110's: 4120's: 4130's: 2140's: 1Data obtained (Smallest to biggest):
70, 80, 90, 90, 100, 100, 100, 110, 110, 110, 110, 120, 120, 120, 120, 130, 130, 140Step-2: Count the number of digits.
18 digits in dataStep-3: Use the formula "Total digits/2".
18/2 = 9th digitThe 9th digit in the data is the median.
Step-4: Revise the data.
70, 80, 90, 90, 100, 100, 100, 110, 110, 110, 110, 120, 120, 120, 120, 130, 130, 140The median value of the line plot is 110.
Answer:
[tex]110 = \text{median}[/tex]
Step-by-step explanation:
We can see that there are:
[tex]\rightarrow \ \ \text{1 "x" on 70} \ \ \ \rightarrow \ \ 70}[/tex]
[tex]\rightarrow \ \ \text{1 "x" on 80} \ \ \ \rightarrow \ \ 80}[/tex]
[tex]\rightarrow \ \ \text{2 "x" on 90} \ \ \ \rightarrow \ \ 90,\ 90}[/tex]
[tex]\rightarrow \ \ \text{3 "x" on 100} \ \ \rightarrow \ \ 100,\ 100, \ 100}[/tex]
[tex]\rightarrow \ \ \text{4 "x" on 110} \ \ \rightarrow \ \ 110,\ 110, \ 110, \ 110}[/tex]
[tex]\rightarrow \ \ \text{4 "x" on 120} \ \ \rightarrow \ \ 120,\ 120, \ 120, \ 120}[/tex]
[tex]\rightarrow \ \ \text{2 "x" on 130} \ \ \rightarrow \ \ 130,\ 130[/tex]
[tex]\rightarrow \ \ \text{1 "x" on 140} \ \ \rightarrow \ \ 140[/tex]
Now, let's put the values in descending form (Greatest --- Smallest). Start from the bottom and go to the top.
[tex]\rightarrow140, 130, 130, 120, 120, 120, 120, 110, 110, 110, 110, 100, 100, 100, 90, 90, 80, 70[/tex]
To find the median of the line plot, we need to check how many numbers are in total. Then, use the correct formula to find out which digit is the median. Lastly, use the "descending" data to find the median.
[tex]\rightarrow 1 + 1 + 2 + 3 + 4 + 4 + 2 + 1[/tex]
[tex]\rightarrow 7 + 11[/tex]
[tex]\rightarrow 18 \ \text{digits}[/tex]
Since 18 is an even number, the correct formula to use is [tex]\frac{n}{2}[/tex], where n is the total digits in the line plot.
[tex]\rightarrow \dfrac{n}{2}[/tex]
[tex]\rightarrow \dfrac{18}{2} = 9^{\text{th}}[/tex]
Now, let's take a look at our "descending" data to see which is the median. Remember, the ninth digit is the median.
[tex]140, 130, 130, 120, 120, 120, 120, 110, \boxed{\bold{110}}, 110, 110, 100, 100, 100, 90, 90, 80, 70\\[/tex]
Thus, 110 is the median.
