Answer:
Look below.
Step-by-step explanation:
39.
10+ = 149 times x
3 - 9 = 143 times x
40.
2(w times 1.5 + w)
Answer: When increasing your multiplying x>1 because 45 times 1 is 45 to get 75 you multiply by approximately 1.65

Answer: F = 211312.5ft/lb.
Step-by-step explanation: Hydrostatic pressure is pressure caused by a fluid due to the force of gravity. It is calculated following the formula:
P = ρgh.
ρ is the fluid density (62.5 lb/ft³);
g is the gravitacional acceleration( 32.2ft/s²);
h is the height of the fluid columm;
P = 62.5.32.2.h
Pressure at h = 1ft:
P = 62.5.32.2.1
P = 2012.5 psi.
Now, hydrostatic force is F =
The pressure exerted on the surface is not constant. It depends on the height. So, to evaluate the force:
dF = P(h) dA
Since it a rectangular plate, dA = w.dh, where w is its width and equals 6 and dh is its height element.
That gives: dF = P(h)w.dh
= 2012.5.6. = 2012.5.6() = 12075() = 211312.5ft/lb.
