Answer:
B) 43.82 feet/sec
Step-by-step explanation:
Fill in the number and evaluate:
v = √(64×30) = √1920 ≈ 43.82 . . . . ft/s
_____
Of course, √(64h) can be simplified to 8√h. You know that √30 lies between 5 and 6, so the velocity lies between 8·5 = 40 and 8·6 = 48. There is only one answer choice in that range.
1.5 because 2/12=1/6 9 x (1/6) =1.5 gallons of water.
Answer:
around 4.1
Step-by-step explanation:
Answer:
x=-37/3
y=-22/3
Step-by-step explanation:
-2x+2y=10 (1)
2x-5y=12 (2)
(1)+(2) <=> -3y=22
Answer:
x=16
Step-by-step explanation:
Pythagorean theorem:
20^2-12^2=256
square root of 256=16
