Mia took the taxi ride for 7 miles not including the tip and pickup fee.
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.

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]

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.

write the factored equation of the following 6th degree polynomial with intercept at (0, 576)
Check the picture below on the left-hand-side.
we know the degree of the polynomial will be 6, so the exponents of its factors must add up to 6.
now, we know that at -4 and -1 it has an odd multiplicity, so the exponent of that factor could be either 3 or 1 hmmm so which is it?
well, when the graph cross the axis straight through, it'd be a multiplicity of 1, when it leans a bit on the axis, like it does on -4, the multiplicity will be larger than 1, so then
[tex]\begin{cases} x=-4\implies &x+4=0\\ x=-1\implies &x+1=0\\ x=3\implies &x-3=0 \end{cases}\qquad \implies a\stackrel{odd\qquad odd\qquad even}{(x+4)^3(x+1)^1(x-3)^2}=y \\\\\\ \stackrel{\textit{we also know that}}{x=0\qquad y=576}\implies a(0+4)^3(0+1)(0-3)^2=576\implies a(64)(1)(9)=576 \\\\\\ 576a=576\implies a=\cfrac{576}{576}\implies a=1~\hfill \begin{array}{llll} 1\stackrel{odd\qquad odd\qquad even}{(x+4)^3(x+1)^1(x-3)^2}=y \\\\\\ \boxed{(x+4)^3(x+1)^1(x-3)^2=y} \end{array}[/tex]

Step-by-step explanation:
Find the length of each side using the Distance Formula.
Find the length of side HA.
HA=(−10−(−6))2+(4−(−2))2−−−−−−−−−−−−−−−−−−−−−−−√
=(−4)2+(6)2−−−−−−−−−−√
=16+36−−−−−−√
=52−−√=213−−√
Find the length of side AT.
AT=(−6−(−10))2+(6−4)2−−−−−−−−−−−−−−−−−−−−√
=(4)2+(2)2−−−−−−−−−√
=16+4−−−−−√
=20−−√=25–√
Find the length of side TC.
TC=(−2−(−6))2+(4−6)2−−−−−−−−−−−−−−−−−−−√
=(4)2+(−2)2−−−−−−−−−−√
=16+4−−−−−√
=20−−√=25–√
Find the length of side HC.
HC=(−2−(−6))2+(4−(−2))2−−−−−−−−−−−−−−−−−−−−−−√
=(4)2+(6)2−−−−−−−−−√
=16+36−−−−−−√
=52−−√=213−−√
Therefore, HA=HC=213−−√ and AT=TC=25–√.
Since there are two pairs of congruent consecutive sides, HATC is a kite by definition.
Find the perimeter of the kite as the sum of the four sides.
P=213−−√+25–√+25–√+213−−√=45–√+413−−√ units
To find the area of the kite, first find the lengths of the diagonals AC and TH using the Diatance Formula.
The figure shows the same quadrilateral H A T C as in the beginning of the task. Diagonal A C is perpendicular to diagonal T H.
Find the length of diagonal AC.
AC=(−2−(−10))2+(4−4)2−−−−−−−−−−−−−−−−−−−−√
=(8)2+(0)2−−−−−−−−−√
=64−−√=8
Find the legth of diagonal TH.
TH=(−6−(−6))2+(−2−6)2−−−−−−−−−−−−−−−−−−−−−√
=(0)2+(−8)2−−−−−−−−−−√
=64−−√=8
Find the area of the kite using the formula for the area of a kite, A=12d1d2.
Substitute 8 for d1 and 8 for d2.
A=12(8)(8)=32 units2
Therefore, the perimeter of the kite is 45–√+413−−√ units and the area is 32 units2.

x- 3=8 solve each equation
Answer:
x=11
Step-by-step explanation:
you need to get x by itself so just add it to the other side and you get x=11
Answer:
x =11
Step-by-step explanation:
x - 3 = 8
To solve the equation, we have to isolate 'x'.
To isolate 'x', we have to add 3 to both sides.
x - 3 + 3 = 8 + 3
x = 11
