A Bathtub has dimensions of 5ft Long, 3ft wide, and 2ft tall. The tub itself weighs 300lbf. The tub contains 100 gallons of wate
mash [69]

Answer:

a) What is the volume of water in ft?

We are given that The tub contains 100 gallons of water

1 UK gallon = 0.1605437 ft^3

So,

100 UK gallon = 100 \times 0.1605437 = 16.05437ft

b)Find the weight of the water in units of Ibf.

Specific weight of water at 100° F =61.862 lbf /ft^3

Weight of water = 61.862 \times 16.05437 lbf = 993.15543694 lbf

c)What is the total weight of tub plus human plus water?

Total weight = Weight of tub + weight of human + weight of water

                     = 300 lbf + 993.155 lbf + 200 lbf = 1493.155 lbsf

d)What is the pressure on the floor in units of psi (Ibf/in2)?

1 feet = 12 inches

Area of floor =5ft \times 3ft = 5 \times 12\times 3 \times 12 =60 in \times 36in = 2160 in^2

Pressure =\frac{\text{Total weight}}{Area} = \frac{1493.155}{2160} lbf /in^2=0.691 psi

Hence the pressure is 0.691 psi

You are thinking about the things that can go wrong on your trip home over the Thanksgiving break. You have booked a flight with
shtirl [24]

Answer:

The probability that the person reaches home for the holidays is 0.94.

Step-by-step explanation:

A person wants to go home for Thanksgiving and he has booked a flight with US-Scareways.

It is provided that in 30 percent of the cases the company has canceled the flight you were on.

SO there is 70% chance of reaching home without any difficulties.

In case the flight is cancelled, then as a backup the person's friend Walter offers a ride home.

Walter also has a 80% chance of giving the ride. So there is 20% chance the person will not be able to reach hone if his flight gets cancelled.

Consider the tree diagram below.

The events are:

FC = flight is cancelled

FT = Flight is on time

H = reaches home

Compute the probability that the person reaches home as follows:

P (Reaching Home) = P (H|FC) × P (FC) + P (FT)

                                =(0.80\times 0.30) +0.70\\=0.24+0.70\\=0.94

Thus, the probability that the person reaches home for the holidays is 0.94.

guys I really need help with part c) I literally have no idea how to this. given that tan(pi/8)=sqrt(2)-1. I am really looking f
damaskus [11]

Answer:

a \geq \frac{1}{\sqrt{2} -1}

Step-by-step explanation:

This equation is more intimidating than the problem you have to solve.


You know that the sine of everything is always between -1 and +1. So for the entire expression to be >= 0, the a*tan(pi/8) bit has to be 1 at least. Given this, we can forget about the sin(...) term of the equation for the remainder of solving it.



You already figured out that tan(pi/8) is sqrt(2)-1.



So what we're saying is a * (sqrt(2) - 1) has to be 1 at least.



If we solve a(sqrt(2)-1) >= 1 for a we get:



a = 1/(sqrt(2)-1)

Solve- the second side of a triangular deck is 4 feet longer than the shortest​ side, and the third side is 4 feet shorter than
ddd [48]

Let the length of the shortest side be x, then the length of the second side is x + 4 and the length of the third side is 2x - 4.

Then, x + x + 4 + 2x - 4 = 52

4x = 52

x = 52/4 = 13

Therefore, the lengths of the sides of the triangle are: x = 13, x + 4 = 13 + 4 = 17 and 2x - 4 = 2(13) - 4 = 26 - 4 = 22.

i.e. 13, 17, 22
