Lisa has a swimming pool that is 60ft by 20 ft. she wants to put a sidewalk around it of uniform width. lisa lives in the country, but she only wants the total area taken up to be 2000 sq ft. how wide should the sidewalk be?

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

answer: (3,11) is your answer.
