The janitor found that it was leaking at a rate of 3 fl oz per minute.How fast was the pipe leaking in gallons per hour?
SSSSS [86.1K]

Answer:

First, you would have to convert fl oz to gallons: 1 fl oz = 0.0078125 gal. Therefore, 4 fl oz = 0.03125 gal.

Then, you would have to convert minutes to hours: 1 minute = 0.01666 hours, or 60 minutes = 1 hour.

From here, you can divide 0.03125 gal by 0.01666 hours OR multiply 0.03125 gal by 60 minutes, giving a rate of 1.87 gallons per hour.

What is the length of line segment YX? 8 units 8 StartRoot 3 EndRoot units 12 units 12 StartRoot 3 EndRoot units.
timurjin [86]

Length of line segment <em>YX </em>is distance of both the ends of it. The length of line segment <em>YX </em>is 8\sqrt{3} units.

<h3>What is length of a line segment?</h3>

The length of a line segment is the measurement of the distance of both the ends of it.

Given information-

In the rectangle YVWX the length of line line segment YV is 24 units.

The rectangle YVWX is shown in the image below.

The angle given in the figure is,

m\angle X=30\\m\angle W=90\\m\angle V=60

Now in the figure of rectangle shown below, the triangle <em>XWV </em>is the right angle triangle.

In this right angle triangle the tan of angle is the ratio perpendicular to the base. thus,

\tan 60=\dfrac{24}{VW}\\\sqrt{3}=\dfrac{24}{VW}\\VW=8\sqrt{3}

As the opposite side of a rectangle are equal. Thus, the length of line segment is <em>VW </em>is equal to the length of the line segment <em>YX</em>. Therefore,

YX=VW=8\sqrt{3}

Hence, the length of line segment <em>YX </em>is 8\sqrt{3} units. The option B is the correct option.

How to find the smallest distance between two lines?
Lostsunrise [7]
Consider two lines in space `1 and `2 such that `1 passes through point P1 and is parallel to vector ~v1 and `2 passes through P2 and is parallel to ~v2. We want to compute the smallest distance D between the two lines.
If the two lines intersect, then it is clear that D = 0. If they do not intersect and are parallel, then D corresponds to the distance between point P2 and line `1 and is given by D = k−−−→ P1P2 ×~v1k k~v1k . Assume the lines are not parallel and do not intersect (skew lines) and let ~n = ~v1 ×~v2 be a vector perpendicular to both lines. The norm of the projection of vector −−−→ P1P2 over ~n will give us D, i.e., D = |−−−→ P1P2 ·~n| k~nk . Example Consider the two lines `1 : x = 0, y =−t, z = t and `2 : x = 1+2s, y = s, z =−3s. It is easy to see that the two lines are skew. Let P1 = (0,0,0), ~v1 = (0,−1,1), P2 = (1,0,0), and ~v2 = (2,1,−3). Then, −−−→ P1P2 = (1,0,0) and ~n = ~v1 ×~v2 = (2,2,2). We then get D = |−−−→ P1P2 ·~n| k~nk = 1 √3. Observe that the problem can also by solved with Calculus. Consider the problem of minimizing the Euclidean distance between two points on `1 and `2. Let Q1 = (x1,y1,z1) and Q2 = (x2,y2,z2) be arbitrary points on `1 and `2, and let F(s,t) = (x2 −x1)2 +(y2 −y1)2 +(z2 −z1)2 = (1+2s)2 +(s + t)2 +(−3s−t)2 = 14s2 +2t2 +8st +4s+1. Note that F(s,t) corresponds to the square of the Euclidean distance between Q1 and Q2. Let’s nd the critical points of F. Fs(s,t) = 28s+8t +4 = 0 Ft(s,t) = 4t +8s = 0 By solving the linear system, we nd that the unique critical point is (s0,t0) = (−1/3,2/3). Since the Hessian matrix of F, H =Fss Fst Fts Ftt=28 8 8 4, is positive denite, the critical point corresponds to the absolute minimum of F over all (s,t)∈R2. The minimal distance between the two lines is then D =pF(s0,t0) = 1 √3.

find the length of a rectangular lot with a perimeter of 140 m if the length is 6 m more than the width.
satela [25.4K]
The width would be x.
the length would be x+6
there are two of each (since it’s a rectangle)
so x+x+x+6+x+6=140
simplify
x= 32
l= 38
w= 32
