Answer:  x = 7

`Step-by-step explanation:

Because the figure shows two triangles that are similar. we can write and solve an equation of ratios:

 9 cm       72 cm

----------- = -----------

3x - 20      56 cm

Cross-multiplying, we get (3x - 20)(72 cm) = (9 cm)(56 cm) = 504 cm²

Dividing both sides by 72 cm, we get:

3x - 20 = (504 cm²) / (72 cm) = 7

Then 3x - 20 = 7, and 3x = 27.  Then x must be 9.

Answer:

47

Step-by-step explanation:

The median is the number which is in the "center" of the number set when listed from least to greatest (or I guess vice versa)

So first you have to list them:

33, 34, 38, 42, 47, 47, 48, 49, 51

Then find the number at the center of the number set. "47"

The median is 47.

3241004551 [841]

540 people can ride the wild river in 1 hour if all of the rafts are used and each raft is full

<u>Solution:</u>

Given, There are 15 rafts available for people to use on the adventure river ride.  

Each raft holds 12 people.  

Then, total people capacity over all rafts = 15 x 12 = 180 people.

The park runs this ride 3 times each hour.  

We have to find how many people can ride the wild river in 1 hour if all of the rafts are used and each raft is full?

Then, <em>total people count who take ride = number of rides x number of people per ride </em>

= 3 x 180  = 540

Hence, 540 people can take ride in 1 hour.
