Distance = rate * time, or rewritten rate = distance / time ---> r = d/t 
<span>4 laps, 1 mile per lap = 4 miles = d </span>
<span>12 minutes = 1/5 of hour (12 min/60 min = 1/5) = t </span>

<span>r = 4/(1/5) mph </span>

svlad2 [7]
Selection B is appropriate.

_____
The signs of the coefficients tell you the binomial factors must have both signs positive (selections B and C only). Selection B produces an x-term that is 15x+15x=30x (as we want); selection C produces an x-term that is 45x+5x=50x (not what we want).

The last customer of the day calls telling you they purchased 96 meters of fencing to fence in a
Lilit [14]

Answer:

Area = 733 m² (to the nearest meter)

Step-by-step explanation:

<u></u>

<u>Formulae</u>

  • Circumference of a circle = 2\pir
  • Area of a circle =  \pir²

      (where r is the radius of the circle)

<u>Find the radius</u>

circumference = 96 m

Using the circumference of a circle formula:

⇒  2\pir = 96

⇒  \pir = 96 ÷ 2 = 48

⇒  r = 48 ÷ \pi = 48/\pi

<u>Find the area</u>

radius r = 48/\pi

Using the area of a circle formula:

⇒  A = \pir²

⇒  A = \pi(48/\pi)²

⇒  A = 2304/\pi

⇒  A = 733.3859778...

⇒  A = 733 m² (to the nearest meter)
