Wewaii [24]3 years ago

Answer:

Step-by-step explanation:

Hello!

Y varies directly with X, meaning that every time X increases/ decreases, the value of Y is modified.

If Y=12 when X=4 then you can say that Y varies 3 times every time X varies 1 unit

12= 4*z

z=12/4= 3

So Y= 3x

With this in mind:

1) x= 8

Y= 3*8= 24

2) x= 3

Y= 3*3= 9

3) Y= 6

Y= 3x

x=Y/3= 6/3= 1

I hope this helps!

pregunta de matematica conteste verdadero o falso el siguiente enunciado : En una razón escrita como fracción el numerador recib
Fantom [35]

Answer: falso.

Step-by-step explanation:

En una fracción, el antecedente siempre es el dividendo (también llamado numerador) y el consecuente es el divisor (también llamado denominador)

Es decir, de momento la parte de: "En una razón escrita como fracción el numerador recibe el nombre de antecedente y el denominador recibe el nombre de consecuente el denominador..."

Es verdadera.

El problema en el enunciado es:

"... el denominador puede ser cualquier número"

Esta parte es falsa, el denominador no puede ser 0.

Entonces el denominador no puede ser cualquier número, y así podemos concluir que el enunciado:

" En una razón escrita como fracción el numerador recibe el nombre de antecedente y el denominador recibe el nombre de consecuente el denominador puede ser cualquier número"

Es falso.

What is the value of x?
Aneli [31]

Answer:415


Step-by-step explanation:

Angle DBE + Angle CBE = 90°

(0.1x-22)° + (0.3x-54)° = 90°

(0.4x - 76)° = 90°

(0.4x)° = 166°

x= 1660/4 = 415


(0.1 415 - 22)° + (0.3 415-54)° = 90°

41.5 - 22 + 124.5 - 54 = 90

166 - 76 = 90

No one seems to be he;ping with this question so please help and show proof of how u got the answer
MA_775_DIABLO [31]

Answer:

C = 60t + 70

Step-by-step explanation:

The total cost of hiring Plumbing Service is given by the equation C = 50t + 70, where C is the total cost in dollar and t is the time in hours.

So, $ 70 is the fixed price and $50 is the rate of charge per hour for the service.

Now if in the next month the rate of charge per hour for the service increased to $60 and the initial charge remains the same then the equation for the total cost of hiring Plumbing Service will become C = 60t + 70. (Answer)
