(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:

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 Phoebe - 3 times as much as Andy
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

Answer:

A busload of campers stopped at a dairy stand for ice cream. They ordered 74 cones, some soft serve at 1.50 each and the rest hard pack at 1.25 each. If the total bill was 100, how many of each type of cone were ordered?

Answers

Answer:

40 of the hard pack, 33 of the soft serve

Step-by-step explanation:

x1.25+b1.50=100

100÷2=50

40×1.25=50

33×1.50=49.5

self check

50+49.5=100

(40) 1.25 + (33) 1.50 = 99.5, cant go any higher than that because the price was 100. 50 cents isnt going to buy the 1.25 hard pack or the 1.50 soft shell. so the answer would be 40 of the hard pack and 33 of the soft serve

The age of the older of two boys is twice that of the younger; 5 years ago it
was three times that of the younger. Find the age of each. pls include steps will mark brainiest

Answers

Answer: The older boy is now 20, the younger boy is now 10.

Step-by-step explanation: Explanation:

Let the age of the older boy now be y

let the age of the younger boy now be x

y = 2x

y-5 = 3(x-5)

simplifying

y = 3x - 10

substituting for y in equation 1

2x = 3x-10

simplifying

x = 10

substituting into 1

y = 20

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

[tex]x-1=0[/tex]
