Answer:
x = 4
y = 10
Step-by-step explanation:
29x - 3 + 15x + 7 = 180 (Linear Pair)
44x + 4 = 180
44x + 4 = 180 - 4
44x = 176
x = 4
29(4) - 3
116 - 3
113
13y - 17 = 113 (Alternate Exterior Angles Theorem)
13y - 17 + 17= 113 + 17
13y = 130
y = 10
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
