If terrance ran 12mph and jesse ran 8mph how long will it take them to run 50 miles

Sholpan [36]

Answer:

Terrance would take 4.2666 hours, Jesse would take 6.25 hours

Step-by-step explanation:

1h/12m per hour x 50m/1h is also 50m/12m per hour = 4.266 hours (round number)

1h/8m per hour is also 50m/8m per hour = 6.25 hours (round number)

A circular garden has a circumference of

omeli [17]

This solution to this problem is predicated on the fact that the circumference is just: $2\pir$ . A straight line going through the center of the garden would actually be the diameter, which is well known to be two times the radius of the circle, so we can say that the circumference is just:

$d\pi$

So, solving for both the radius and the diameter gives us:

$d\pi=8xy^2\pi\\ d=8xy^2\\ \\ 2\pi r=8xy^2\pi\\ r=4xy^2$

So, the length of thes traight path that goes through the center of the guardain is just $8xy^2$ , and we can use the radius for the next part of the problem.
