It take zoe 2.5 minutes to swim 20 laps around the pool what is zoe's unit rate

Time taken to swim 20 laps = 2.5 minutes

Hence, time taken to swim 1 lap will be = =0.125 minutes

Or convert it into seconds = seconds

Hence, Zoe's swim rate is 1 lap per 0.125 minutes. Or 1 lap per 7.5 seconds.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
