Answer:
260 nesting turtles were at this sanctuary last year
Step-by-step explanation:
Given:
The number of nesting turtles decreased = 10%
Number of turtles present in sanctuary this year = 234
To Find:
Number of nesting turtles present at this sanctuary last year= ?
Solution:
Let the number of nesting turtles present at this sanctuary last year be x
Then,
x- 10% of x = Number of turtles present in sanctuary this year
x- 10% of x = 234
x= 260
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
