The Turner family and the Cooper family each used their sprinklers last summer. The water output rate for the Turner family's sprinkler was 20L per hour. The water output rate for the Cooper family's sprinkler was 35L per hour. The families used their sprinklers for a combined total of 65 hours, resulting in a total water output of 1825 L. How long was each sprinkler used?

true

step-by-step explanation:

44

step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

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
