Elizabeth swims 50 feet in ten seconds jesse swims 110 feet in 20 seconds reagan swims 160 feet in half a minute. who swims fastest

Jesse swims the fastest with the rate of 5.5 ft in 1 second.

Step-by-step explanation:

The swimming rate of Elizabeth is:   50 feet in 10 seconds

So, the swimming rate per second is

⇒Elizabeth swims 5 ft in 1 second.

Similarly,the swimming rate of Jesse is:   110 feet in 20 seconds

So, the swimming rate per second is

⇒Jesse swims 5.5 ft in 1 second.

Also,the swimming rate of Reagan is:   160 feet in 30 seconds

So, the swimming rate per second is

⇒Reagan swims 5.33 ft in 1 second.

By comparing the per second rate of swimming,

5.5 is the greatest of the all rates.

Hence, Jesse swims the fastest with the rate of 5.5 ft in 1 second.

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
