3. Bob Baffert hos iwo thoroughbred horses in his bom that he brings out
natima [27]

Answer:

12.5r + 200 = 12.5*2r

Step-by-step explanation:

<h3>Given</h3>

Rate of Hoppertunity = r

Rate of Dortmund = 2r as it is twice as fast

<h3>Solution</h3>

Let the distance Hoppertunity runs be d, then the distance Dortmund runs is d + 200 m

Since it took 12.5 seconds Dortmund to catch Hoppertunity, it can be expressed as:

  • d = 12.5r for Hoppertunity
  • d + 200 =12.5*2r for Dortmund

<u>By replacing d in the second equation, we get:</u>

  • 12.5r + 200 = 12.5*2r

<u>Soving</u>:

  • 12.5r = 200
  • r = 200/12.5
  • r = 16 m/sec

Hoppertunity's rate is 16 m/sec

Dortmund's rate is 32 m/sec

Simplify: 30 - 23 × 3
gogolik [260]
The answer to this question would be 39..here is why:

First you multiply 23 x 3..because multiplication or division always comes before addition or subtraction.

Second, you get the product from 23 x 3 which is 69..and you subtract 30 from that.

Last, after you do that you get an over all answer of 39..
