Answer:

2hr

Step-by-step explanation:

Let x be the flow rate of the first line in kg/hr

Let y be the flow rate of the second line kg/hr

Let V be the volume of the pond. in kg

(2 hr)(x kg/hr) = V kg

(1 hr)(x + y kg/hr) = V kg

x + y = 2x

y = x

as the flow rates of the two lines is identical, the second line alone takes two hours to fill the pond.

svlad2 [7]

Answer:

24) $495

25) 14%

26) 25/X = 83/100

27) 0.7p

28) x + .085x and 1.085x

29) $221.90

30) $24.10

31) $6.13

32) 40%

Step-by-step explanation:

24) 600 - (600 × 0.25) = 450

450 × 1.10 = 495

25) (106 - 93) ÷ 93 = 0.13978

0.13978 × 100 = 13.978 ~ 14

27) 1.0 - 0.3 = 0.7

28) 1.00 + 0.085 = 1.085

29) 100% - 15% = 85%

240 × 0.85 = 204

204 × 1.0875 = 221.85

30) 25.89 × 4 = 103.56

103.56 + 179.99 = 283.55

283.55 × 0.085 = 24.10175

31) 8.75 × 0.70 = 6.125

32) 80 - (80 × 0.40) = 48
