Answer:

Julio terminará pagando $3285.25 por el celular.

Step-by-step explanation:

Con la información proporcionada, puedes encontrar cuánto terminará pagando Julio por el celular calculando el 15% del precio del celular dado que ese sería el valor del descuento y luego, tienes que restar ese valor del precio del celular:

$3865*15%=$579.75

$3865-$579.75=$3285.25

De acuerdo a esto, la respuesta es que Julio terminará pagando $3285.25 por el celular.

GIVING BRAINLIEST Write a proportion that could be used to solve for each variable. Then solve. 7 pencils for $1.68 p pencils fo
Evgesh-ka [11]

The proportion that could be used to solve for the variable is:

\frac{7}{1.68}=\frac{p}{2.88} ; p = 12 ⇒ b

Step-by-step explanation:

Direct proportion means that two (or more) quantities increase or decrease in the same ratio

  • y = k x is the equation of direct proportion, where k is the constant of proportionality
  • \frac{y_{1}}{x_{1}}=\frac{y_{2}}{x_{2}}=k is the another way to write a proportion

The number of pencils and the cost of them is increased together or decreased together

∴ The number of the pencils and their costs are in direct proportion

- By using the 2nd rule above

∵ The cost of the 7 pencils is $1.68

∵ The cost of p pencils is $2.88

∴ \frac{7}{1.68}=\frac{p}{2.88}

The proportion that could be used to solve for the variable is: \frac{7}{1.68}=\frac{p}{2.88}

∵ \frac{7}{1.68}=\frac{p}{2.88}

- By using cross multiplication

∴ p × 1.68 = 7 × 2.88

∴ 1.68 p = 20.16

- Divide both sides by 1.68

∴ p = 12

The value of variable p is 12

How many unique planes can be determined by four noncoplanar points?
marta [7]

Answer:

Four unique planes

Step-by-step explanation:

Given that the points are non co-planar, triangular planes can be formed by the joining of three points

The points will therefore appear to be at the corners of a triangular pyramid or tetrahedron such that together the four points will form a three dimensional figure bounded by triangular planes

The number of triangular planes that can therefore be formed is given by the combination of four objects taking three at a time as follows;

₄C₃ = 4!/(3!×(4-3)! = 4

Which gives four possible unique planes.
