Answer:
48%
Step-by-step explanation:
This is a very simple problem of finding percentage.
To find percentage of people preferring pizza, we need to divide "number of person who like pizza" by the "total number of person".
So, that's
240/500
And then we need to multiply by 100 and tag a "%" sign at the end. So let's do this:
So 48% of the people chose pizza.
Answer:
88 centimeters is the diameter of the cilinder
Step-by-step explanation:
The pressure on both ends of the lift must be the same. Assuming the piston is cilindrical, its area will be A=π*r² where r is half the diameter
Since pressure P=F/A And P1=P2
F1=2000kg.g
A1=π*r²
F2=25kg.g
A2=π*0.05²
2000/(π*r²)=25/(π*0.05²)
and we solve for A1
r²=2000*0.05²/25
r=20*0.05/5=0.44m or 44cm
This is the radius, meaning that the diameter will be twice this number
