The Rodriguez family and the Alexander family each used their sprinklers last summer. The water output rate for the Rodriguez family's sprinkler was 40 L per hour. The water output rate for the Alexander family's sprinkler was 35 L per hour. The families used their sprinklers for a combined total of 45 hours, resulting in a total water output of 1700 L. How long was each sprinkler used?

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

6 cm

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
