The Smith family sprinkler was used for 25 hours and the Figueroa family sprinkler was used for 35 hours. The combined total output was 1850L of water. What was the water output for each sprinkler if the sum of the two rates was 60L per hour?

what

thus, the first answer choice, y = sec x, is the correct one

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
