Answer:
[tex]m\angle QPO + (2x+16)^\circ = 180^\circ[/tex]
Step-by-step explanation:
In a cyclic quadrilateral, opposite angles add up to 180 degrees. Therefore, our answer would be the third answer, [tex]m\angle QPO + (2x+16)^\circ = 180^\circ[/tex], where QPO and QRO are opposite of each other.

- 98Step-by-step explanation:
Given
[tex]a_{21}=-32[/tex][tex]a_{50}=-119[/tex]Find [tex]a_{43}[/tex]
We know that
[tex]a_n=a_1+(n-1)d[/tex]Appy this to the two known terms and find the first term and the common difference
[tex]a_1+20d=-32[/tex] ⇒ [tex]a_1=-20d-32[/tex] [tex]a_1+49d=-119[/tex] ⇒ [tex]a_1=-49d-119[/tex]Find the coomon difference
-20d - 32 = - 49d - 11949d - 20d = 32 - 11929d = - 87d = - 87/29d = - 3Find the first term
a₁ = - 20(- 3) - 32 = 60 - 32 = 28Now find the 43th term
a₄₃ = 28 + 42(- 3) = 28 - 126 = - 98Answer:
-98
Step-by-step explanation:
General form of an arithmetic sequence:
[tex]a_n=a+(n-1)d[/tex]
where:
[tex]a_n[/tex] is the nth terma is the first termd is the common difference between termsGiven:
[tex]a_{21}=-32[/tex][tex]a_{50}=-119[/tex]To find the 43rd term we need to construct an equation for the nth term. To do this, find the first term and the common difference by substituting the given information into the general formula to create a system of equations that can be solved.
[tex]\begin{aligned} \underline{\textsf{Equation 1}}} \\ a_{21} & =-32 \\ \implies a+(20-1)d & = -32 \\a+20d & =-32 \end{aligned}[/tex]
[tex]\begin{aligned} \underline{\textsf{Equation 2}}} \\ a_{50} & =-119 \\ \implies a+(50-1)d & = -119 \\a+49d & =-119 \end{aligned}[/tex]
Subtract Equation 1 from Equation 2 to eliminate a:
[tex]\begin{array}{r l}a+49d & = -119\\- \quad a+20d & = -32\\\cline{1-2}29d & = -87\end{aligned}[/tex]
Solve for d:
[tex]\implies d=\dfrac{-87}{29}=-3[/tex]
Substitute the found value of d into one of the equations and solve for a:
[tex]\implies a + 20(-3)=-32[/tex]
[tex]\implies a=28[/tex]
Substitute the found values of a and d into the general formula to create an equation for the nth term:
[tex]\implies a_n=28+(n-1)(-3)[/tex]
[tex]\implies a_n=31-3n[/tex]
Finally, substitute n = 43 into the found formula to find the 43rd term of the sequence:
[tex]\implies a_{43}=31-3(43)=-98[/tex]

Calculate the mean of the data set below. 28,40,53,39,45
Answers
Answer: 41.
Step-by-step explanation: To find the mean of a data set, you first need to add all the numbers together. It should look like this:
28 + 40 + 53 + 39 + 45 = 205.
The next step is to divide 205 by how many numbers you have in the data set. In this case, you have 5 numbers in the data set. Your work should look like this:
205 / 5 = 41.
Therefore, the mean of the data set is 41.
Hope this helps! :)

Linda rented 8 movies and 4 video games for a total of $37. The next month she rented 3 movies and 2 video games for a total of $17.
Find the rental cost for each movie and video game.
Answers
Rental cost for each video game $6.25
Explanation:
m = rental cost of each movie
g = rental cost of each game
Set up:
8m + 4g = 37
3m + 2g = 17
Modify for elimination:
3 (8m + 4g = 37) ———> 24m + 12g = 111
8 (3m + 2g = 17) ———> 24m + 16g = 136
Subtract:
24m + 16g = 136
- 24m - 12g = -111
——————————
4g = 25
Divide:
4g = 25
g = 25/4
g = 6.25
So each game is $6.25
Now plug in “g” to one of the original equations and solve for “m” to find the rental cost for each movie
3m + 2 (6.25) = 17 (multiply 2 & 6.25)
3m + 12.50 = 17 (subtract 12.50 from sides)
3m = 4.50 (divide both sides by 3)
m = 1.50
So each movie rental is $1.50

Hi ok heres how I did this:
SA of rectangular prism: S = 2(lw + lh + wh)
SA of triangle top thing(whats it called???): Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area) = (S1 + S2+ S3)L + bh
So basically for the square part, the surface area is
2(4*4+4*12+4*12), or 224
For the triangle part, the surface area is
4+4+4, or 12*4+2*4, or 48+8, or 56
224+56=280

Workout a b and c
Answers
Answer:
a=21° b=70°
Step-by-step explanation:
a=21°(Vertically Opposite Angles)
b+110°=180° (linear pair)
b=180-110
b=70°
[please mark me brainliest]
Answer:
a = 21°
b = 70°
c = 89°
Step-by-step explanation:
angle of measure b and the angle of measure 110 are two supplementary angles
Then b + 110 = 180
Therefore b = 180 - 110 = 70°
angle of measure b and the angle of measure 21 are two opposite angles
Then a = 21
We Know that the sum of the interior angles of a triangle equal to 180
Then a + b + c = 180
Therefore c = 180 - a - b = 180 - 21 - 70 = 159 - 70 = 89°

expand and simplify 2(3a-5b +4 (a+2b)
Answers
Answer:
14a + 6b
Step-by-step explanation:
To expand use distributive property. a*(b +c) =a*b +a *c
Simplifying an expression
2*(3a - 5b + 4*(a+2b) = 2*(3a -5b + 4*a +4*2b)
= 2*(3a - 5b + 4a + 8b)
= 2* (3a + 4a - 5b + 8b)
Combine like terms. To combine like terms, add or subtract the coefficient of the variables. 3a and 4a & (-5b) and 8b are like terms
= 2*( 7a + 3b)
= 2*7a + 2*3b
= 14a + 6b
Hey there!
2(3a - 5b) + 4(a + 2b)
= 2(3a - 5b) + 4(1a + 2b)
= 2(3a) + 2(-5b) + 4(1a) + 4(2b)
= 6a - 10b + 4a + 8b
= (6a + 4a) - (10b + 8b)
= 6a + 4a - 10b + 8b
= 10a - 2b
Therefore, your answer is: 10a - 2b
