Answer:
See each answer bolded below
Step-by-step explanation:
1. Area of the rectangle is 20 * 30 = 600
Area of the 6 circles is 6(25pi)
150pi/600 = 0.7854
1 - 0.7854 = 0.2146
convert to percentage 21.46%
2. 6/16 -> 3/8
Roughly 38% (37.5)
3. 10/24 = 0.41666666667 or 0.4167
41.66
roughly 42%
4. 12/36 -> 1/3
33.3333
33%
Answer:
They will need 200kg of pine logs.
Gauge pressure in the tank = 24045.29 Pa
Absolute pressure= 125370.29Pa
Step-by-step explanation:
Full question:sp.gr=0.8.The fluid in the nanometer is ethyl iodide with sp.gr =1.93. The manometric fluid height is 50 inches. What is the gauge pressure and absolute pressure in the tank?
Converting 50inches to metres. Multiply by 0.0254
50×0.0254=1.27m
Gauge pressure in tank is given by:
P = pgh
Where p= density,g= acceleration due to gravity, h= height
P= 1.93× 1000× 9.81× 1.27= 24045.29Pa
Absolute pressure=Ptotal= Pliquid + Patm
Absolute pressure =24045.29 + 101325=125370.29pa
You at the photos and what you see put it down and what you know put it down
(15 minutes/hour) x (1 spot / 1/2 minute) x (24 hour/day) = <u><em>720</em></u> spots/day
The tax rate is 5%
Hope this helps!
