(M1219Q3SP) Um aplicativo de transporte de passageiros cobra uma taxa de R$ 0,75 por viagem, chamada de "Custo Fixo". Além dos R$0,75, a tarifa do aplicativo tem preço base inicial de R$2 e cobra R$1,40 por quilômetro rodado e R$ 0,26 por minuto de viagem. Considerando a distância percorrida em quilômetros igual a “q” e o tempo de viagem em minutos igual “t”, qual a função que representa o valor a ser cobrado por uma viagem usando esse aplicativo de transporte de passageiros é:
Answers
Somando todas as despesas, a função é dada por:
[tex]C(q,t) = 2.75 + 1.4q + 0.26t[/tex]
----------------------
Custo fixo de R$ 0,75:
Isto implica que:
[tex]C = 0.75[/tex]
As outras despesas são:
Preço base de R$ 2 mais 1,40 por cada quilômetro q.R$ 0,26 por cada minuto t de viagem.Então, a função é:
[tex]C(q,t) = 0.75 + 2 + 1.4q + 0.26t[/tex]
[tex]C(q,t) = 2.75 + 1.4q + 0.26t[/tex]

Mina opens a book 15 times and records whether the page number is
even or odd. How many trials did she conduct?
Answers
Answer:
She made 15 trials
Step-by-step explanation:
Well it said that she opened the book 15 times in total and records each time so the answer would be 15.
Mina conducted 15 trials in total.
What are trials? What is probability? In probability theory, an experiment or trial is any procedure that can be infinitely repeated and has a well-defined set of possible outcomes, known as the sample spaceThe formula to calculate the probability of occurrence of an event [A] can be written as -P(A) = n(A)/n(S)
where -
n(A) = Number of outcomes favorable to event A.
n(S) = Total number of outcomes.
We have Mina opens a book 15 times and records whether the page number is even or odd.
Since she opens the book 15 times, she conducted 15 trials in total.
Therefore, Mina conducted 15 trials in total.

Find the solution set for 8x^-9x=-1
Answers
Answer:
[tex]\mathrm{The\:solutions\:to\:the\:quadratic\:equation\:are:}[/tex]
[tex]x=\frac{1}{8},\:x=1[/tex]
Step-by-step explanation:
Given the equation
[tex]8x^2-9x=-1\:\:[/tex]
Add 1 to both sides
[tex]8x^2-9x+1=-1+1[/tex]
[tex]8x^2-9x+1=0[/tex]
as
[tex]\left(8x-1\right)\left(x-1\right)=8x^2-9x+1[/tex]
so the equation becomes
[tex]\left(8x-1\right)\left(x-1\right)=0[/tex]
Using the zero factor principle:
[tex]\:If}\:ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)[/tex]
so
[tex]8x-1=0\quad \mathrm{or}\quad \:x-1=0[/tex]
solving
[tex]8x-1=0[/tex]
[tex]8x=1[/tex]
[tex]\frac{8x}{8}=\frac{1}{8}[/tex]
[tex]x=\frac{1}{8}[/tex]
also solving

Help please xxxxxx please

Answer: x = 84°.
Step-by-step explanation: The sum of interior angles of a quadrilateral is equal to 360°. We are given three of the interior angles and asked to find the remaining angle. To do this, we can add the three given angles and subtract the sum from 360°. 53° + 125° + 98° = 276°. 360° - 276° = 84°. Thus, x = 84°.

pheobe andy and polly share £270 pheobe gets three times as much as andy who hets twice as much as polly how much do they each get
Answers
Money of Andy - 2 times as much as Polly
Total money of Phoebe, - £270
Andy and Polly
*Solution
Let
B - Phoebe's money
A - Andy's money
L - Polly's money
1. The money of the Phoebe, Andy, and Polly, when added together would total £270. Thus,
B + A + L = £270 (EQUATION 1)
2. Phoebe has three times as much money as Andy and this is expressed as
B = 3A
3. Andy has twice as much money as Polly and this is expressed as
A = 2L (EQUATION 2)
4. This means that Phoebe has ____ as much money as Polly,
B = 3A
B = 3 x (2L)
B = 6L (EQUATION 3)
This step allows us to eliminate the variables B and A in EQUATION 1 by expressing the equation in terms of Polly's money only.
5. Substituting B with 6L, and A with 2L, EQUATION 1 becomes,
6L + 2L + L = £270
9L = £270
L = £30
So, Polly has £30.
6. Substituting L into EQUATIONS 2 and 3 would give us the values for Andy's money and Phoebe's money, respectively.
A = 2L
A = 2(£30)
A = £60
Andy has £60
B = 6L
B = 6(£30)
B = £180
Phoebe has £180
