9 times 82 in application of distributive property
1 answer:
The term 9 times 82 in application of distributive property can be written as:
Step-by-step explanation:
We need to rewrite the term 9 times 82 in application of distributive property.
The distributive property says that: a(b+c)=ab+ac
We are given:
Writing 82 as (80+2)
the equation will be:
Now, applying distributive property: a(b+c)=ab+ac
if we multiply 9 times 82 we get 738 which is same as 9\times (80+2)
The term 9 times 82 in application of distributive property can be written as:

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
