Pressure<span> is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. We calculate the pressure applied to the system above by the expression:
P = F / A
where F = mg
P = mg / A
P = (7.5 x 9.8) / 0.6
P = 122.5 Pa</span>
The answer to this question is 81
Answer:
1m----------3.28084ft
400m---------xft
x=(400*3.28084)/1
x=1,312.33 ft
Step-by-step explanation:
Ax+by=c
y=x+3
subtract x from both sides
Y-x=x-x+3
Y-x=3
-1•(y-x)=-1•3
-y+x=-3
Reorder:
X-y=-3
I’m not sure if it’s 100% correct but that’s all I can do
Answer:
There are an infinite number of values satisfying the requirements; every couple of numbers satisfying the following conditions are valid:
base = 60-w meters
width = w meters
0 < w <= 22
Step-by-step explanation:
Since the playground has a rectangular shape, let us us call b the base of the rectangle and w its width. In order for the rectangle to satisfy the condition of P = 120, we need for the following equation to satisfy:
2b + 2w = 120
Solving for b, we get that b = (120 - 2w)/2 = 60 - w .
Given a particular value (w) for the width, the base has to be: (60-w).
Therefore, the possible lengths of the playground are (60-w, w), where 60-w corresponds to the base of the rectangle and w to its width. And w can take any real value from 0 to 22.
