7 0

Answer:

Espero que isto ajude!

Step-by-step explanation:

q  duplica  logo a razão q =2

1 hora = 60 minutos

4 hs *  60 min = 240 minutos ou 240 : 6    = 40  vezes   6 minutos

Nota >  240 minutos tem 40 * 6 minutos

n = 40

a1 = 6 min  = 3

a2 = 12 min = 3 * 2 = 6

q3 = 18 min  =  6  *2  =12

an = a1 * q^n-1

a40  = 3 * 2^40-1

a40 = 3 * 2^39

a40  = 3 * 5497559  =16492677 >>>>>

A line has a slope of 1/5 and a run = 30. What is the<br> rise?
pashok25 [27]

Answer:

<h2>rise = 6</h2>

Step-by-step explanation:

slope=\dfrac{rise}{run}\\\\\text{We have}\\\\slope=\dfrac{1}{5},\ run=30\\\\\text{Substitute:}\\\\\dfrac{1}{5}=\dfrac{rise}{30}\qquad\text{cross multiply}\\\\5rise=(1)(30)\\\\5rise=30\qquad\text{divide both sides by 5}\\\\\dfrac{5rise}{5}=\dfrac{30}{5}\\\\rise=6

Una botella de agua de medio decimetro cubico se llena en 35 segundos .Con el mismo flujo de agua,¿En cuantos minutos se llenari
Amanda [17]

Answer:

5,250 minutes

Step-by-step explanation:

0.5 cubic Centimeter = 0.0005 liter

So, 4.5 liters = 4,500 cubic Centimeter

Time required for 0.5 cubic Centimeter = 35 seconds

So, we can calculate the total time required by using following formula

Total time required = (Time required for 0.5 cubic Centimeter × 2 ) × 4,500 cubic Centimeter

So, Total time required = (35 seconds ×2 ) × 4,500

= 70 × 4,500

= 315,000 seconds

= 5,250 minutes

Which of these statements is correct?
mariarad [96]

Answer:

The answer to your question is the third choice.

Step-by-step explanation:

a)          6x - 5y = 8

           12x - 10y = 16

We observe that these lines are the same so they have infinite solutions.

b)

            7x + 2y = 6

           14x + 4y = 16

These lines are parallel because they have the same slope, so they do not cross, there is no solution.

c)

             8x - 3y = 10

            16x - 6y = 22

These lines are parallel because they have the same slope, so they do not cross, there is no solution.

d)

            9x + 6y = 14

           18x + 12y = 26

These lines are parallel because they have the same slope, so they do not cross, they do not have an infinite number of solutions.
