Answer:

  1.3363

Step-by-step explanation:

The basic idea here is to find an expression for the direction vector between a point on L1 and a point on L2. Then, solve for the points on L1 and L2 that make that vector perpendicular to both lines L1 and L2. (The dot product of direction vectors is zero.) The distance between the points found is the shortest distance between the lines.

__

Let P be a point on L1. Then the parametric equation for P is ...

  P = (6t, 0, -t) . . . . . . origin + t × direction vector

Let Q be a point on L2. The direction vector for L2 is given by the difference between the given points. It is (4-1, 1-(-1), 6-1) = (3, 2, 5). Then the parametric equation for Q is ...

  Q = (3s+1, 2s-1, 5s+1) . . . . (1, -1, 1) + s × direction vector

The direction vector for PQ is ...

  Q -P = (3s+1-6t, 2s-1, 5s+1+t)

The dot product of this and the two lines' direction vectors will be zero:

  (3s+1-6t, 2s-1, 5s+1+t)·(6, 0, -1) = 0 = 13s -37t +5 . . . perpendicular to L1

  (3s+1-6t, 2s-1, 5s+1+t)·(3, 2, 5) = 0 = 38s -13t +6 . . . perpendicular to L2

The solution to these equations is ...

  s = -157/1237

  t = 112/1237

Then (Q-P) becomes (94, -1551, 564)/1237, and its length is ...

  |PQ| = √(94² +1551² +564²)/1237 ≈ 1.3363

The distance between the two lines is about 1.3363 units.

Of the 64 students on a field trip to a museum, five-eighths brought their lunch. How many students brought their own lunch?

A. 39
B. 46
C. 40
D. 38

Answers

Answer:

C. 40

Step-by-step explanation:

1. To find how many students brought their own lunch, we have to multiply 5/8 by 64.  

[tex]\frac{5}{8} * 64[/tex] [tex]\frac{5}{1}* 8[/tex] [tex]40[/tex]

Therefore, the answer is C. 40.

The correct answer is 40 (C)
To find this answer, you must divide the amount of students by the denominator, which would be 64/8 which is 8. Then, you must multiply by the numerator, (8x5) which is 40.

Step-by-step explanation:

The volume of the triangular prism (green) is the area of the base multiplied by the height.

The base is the front surface which is a triangle with base 6 cm and height 7 cm.

The height of the prism is 6 cm.

V = AH

V = (1/2)bhH

V = (1/2)(6 cm)(7 cm)(6 cm)

V = 126 cm^3

The volume of the green triangular prism is 126 cm^3

The total volume of the composite solid is the sum of the two volumes.

Total Volume = 336 cm^3 + 126 cm^3

Total Volume = 462 cm^3
