Answer:

  25

Step-by-step explanation:

Each of the 16 "ratio units" representing all 80 dancers must stand for ...

  (80 dancers)/(16) = 5 dancers

Then 5 "ratio units" representing seventh-grade dancers will stand for ...

  5 × 5 dancers = 25 dancers

___

Another way to figure this is to write the proportion ...

  (seventh-grade dancers)/(all dancers) = 5/16

  seventh-grade dancers = (all dancers)×(5/16) = 80×5/16

  seventh-grade dancers = 25

Wilmer went up a hill for x minutes at a speed of y kilometers per minutes. Then he went down the same path at a speed of z kilo
dedylja [7]

Answer:

xy=wz

Step-by-step explanation:

Given that:

Speed of Wilmer up the hill = y km/min

Time taken up the hill = x minutes

Speed of Wilmer down the hill = z  km/min

Time taken up the hill = w minutes

Distance can be calculated by multiplying the Speed with Time i.e.

The formula for distance is given as:

Distance = Speed \times Time

Distance up the hill = y\times x =xy\ kilometers

Distance down the hill = z\times w =wz\ kilometers

It is well known that, the distance up the hill and down the hill will be same.

Putting both the values equal, we get:

xy=wz
