Answer:

8

Step-by-step explanation:

Let,

t1 = 27

t2 = 18

t3 = 12

t2 / t1

= 27 / 18

= 3 / 2

t3 / t2

= 18 / 12

= 3 / 2

Common ratio = 3 / 2 = 1.5

t4 = t3 / 1.5

= 12 / 1.5

= 12 x 2 / 3

t4 = 8

For each peak, the ball decreases it's height from the ground by 1 / 1.5 times, Using sequence, we can find the height of ball from the ground for different levels of peaks.

Here, we may use Geometric Progression

The sequence follows as:

27, 18,12,...

The first term (a)= 27

27/18 = 18/12

common ratio = 1.5

Let fourth term be x

Therefore , 12/x = 1.5

=> x= 12/1.5 = 8

What is an equation between x (top) and y(bottom)?
Anna35 [415]
Um you would have to do a certain formula which is x2 - x1 over y2 - y1 wo, it would look like this let me show you an example x1 is 12 and x2 is 24, y1 is 2 and y2 is 4 so it would be like this 24 - 12 over 4 - 2 so to do that all you have to do is subtract now which is 4 - 2 = 2 and 24 - 12 is 12 so your answer would tecnically be 12 over 2 I hope this helped you out

Solve the equation <br> 3 1/4x=7 3/7
Artist 52 [7]

Answer:

\frac{217}{292}

Step-by-step explanation:

the given equation is

\frac{31}{4x} = \frac{73}{7}

cross multiplication gives

⇒ 31 * 7 = 4x * 73

⇒ 217 = 292 x

Dividing both sides by 292 will lead us to

⇒ \frac{217}{292} = \frac{292*x}{ 292}

cancelling out 292 on RHS

⇒ \frac{217}{292} = x

or

x=\frac{217}{292}
