Answer:
1.28 m
Step-by-step explanation:
The speed at which water rises in the tank is proportional to the speed of the water in the pipe and inversely proportional to the ratio of the tank area to the pipe area.
The ratio of tank area to pipe area is the square of the ratio of their diameters:
((150 cm)/(4 cm))² = 1406.25
Then the rate of rise of water in the tank is ...
(0.5 m/s)/(1406.25)
After 1 hour = 3600 seconds, the height of the water will be ...
rise = (time)(rate of rise)
(3600 s)(0.5 m/s)/1406.25 = 1.28 m
I hope this helps you
x= -1 f (-1)=(-1)^2+7=1+7=8
g (f (-1))= g (8)
x=8 g (8)= 8-4/8=4/8=1/2
Answer:
Step-by-step explanation:
First convert £ 300 to Yen
£1 = ¥ 168
£300 = 168 * 300 = ¥ 50400
As bank as ¥ 1000 notes, the money he get is ¥50,000
50000 ÷ 1000 = 50
Kevin gets 50 notes of ¥ 1000
Answer:
7
Step-by-step explanation:
So if w/5 = 49/35, then you can take w/5 and make the denominator 35 by multiplying the top and bottom by 7:
w/5 * 7/7 = 7w/35
So then you have:
7w/35 = 49/35
Which means:
7w = 49
w = 7
