Ana pago $350 por 6 pizzas ¿cuánto le costó cada una?​

Mathematics
1 answer:
atroni [7]3 years ago

Usando proporciones y regla de três, tiene-se que cada pizza le costó $58.33.

  • Para encontrar el precio de cada pizza, usa-se proporciones, aplicando una regla de três.
  • A medida que aumenta la cantidad, también lo hace el precio, por lo que las medidas son directamente proporcionales y se aplica la multiplicación cruzada.
  • $350 por 6 pizzas.  ¿cuánto por 1?

La regla de três es:

$350 - 6 pizzas

x - 1 pizzas

Aplicando multiplicación cruzada:

6x = 350

x = \frac{350}{6}

x = 58.33

Un problema similar, que tambíem involucra proporciones, es dado en brainly.com/question/24617308

HELP ME PLEASE!<br><br> In triangle FGH, GH=1, FG=12, and GH=sq. root of 145
topjm [15]

Answer:

B&C: tan F=0.0833 & tan H=12.0000

Step-by-step explanation:

The tangent relationship is always opposite/adjacent.

When F is the reference angle, side GH (1) is the opposite side and side FG (12) is the adjacent.

1/12 is 0.0833

When H is the reference angle, FG (12) is the opposite and GH (1) is the adjacent.

12/1 is 12.

Find the equation of the tangent to the circle x2 + y2 = 109 at point (-10,3)
konstantin123 [22]

Answer:

10x - 3y = -109 .

Step-by-step explanation:

x^2 + y^2 = 109

Implicit Differentiation:

2x + 2y.y' = 0

y' = -2x/2y = -x/y

So at the point (-10,3) the gradient of the tangent is -(-10)/3 = 10/3.

Equation of the tangent:

y - y1 = m(x - x1)

y - 3 = 10/3(x + 10)

y - 3 = 10/3 x + 100/3

3y - 9 = 10x + 100

-109 + 3y = 10x

10x - 3y = -109

X + 14 = 56 What would I do to both sides to answer this equation? O Multiply both sides by 14 © Subtract both sides by 14 Subtr
Lorico [155]

To solve for X in this equation, you would subtract both sides by 14 because our goal is to get X on its own. If we write it out, we see that

X + 14 - 14 = 56 - 14

X=42

Because we have a positive 14, a negative 14 will average out to be 0, but what you do to one side, you must do to the other.
