Rectangle with a length of 96 inches and width of 60 inches. A rug maker wants to increase each dimension by a different amount.
mr Goodwill [35]

Answer:

The perimeter of the new rectangle in simplified expression can be given as:

2l+2w+312

Step-by-step explanation:

The question is incomplete.

The actual question should be:

A rug maker is using a patter that is a rectangle with a length of 96 inches and a width of 60 inches. The rug maker wants to increase each dimension by a different amount. Let l and w be the increases in inches of the length and width. write and simplify an expression for the perimeter of the new pattern.

Solution:

Original length of the rectangular pattern = 96 inches

Original width of the rectangular pattern = 60 inches

Let increase in length be = l inches

New length of rectangle = (96+l) inches

Let increase in width be = w inches

New width of rectangle = (60+w) inches

The perimeter of a rectangle is given by :

⇒ 2(length+width)

Substituting the new length and width of the triangle.

⇒ 2(96+l+60+w)

Simplifying.

⇒ 2(l+w+156)

Using distribution.

⇒ 2l+2w+312

Thus, the perimeter of the new rectangle in simplified expression can be given as:

2l+2w+312

PLEASEEEE HELPPPPP MEEEEEE!!!!<br> Find h in the diagrams below.
Leno4ka [110]

Answer:

  • 9.6
  • 11.2

Step-by-step explanation:

It is useful to label the diagram so we can talk about the parts. (See the attachment.)

AB and CD are parallel lines, crossed by transversal AE. So, angles FAE and CDE are congruent. These are acute angles in a right triangle, so the triangles AFD and DEC are similar by the AA postulate.

This similarity means that corresponding sides are proportional:

  CE/CD = DF/DA

  CE = CD(DF/DA) = 16(6/10) = h

  h = 9.6

__

The second problem is identical to the first, but with different numbers.

  CE = CD(DF/DA) = 14(8/10) = h

  h = 11.2

Answer:

By summing cylindrical slabs of infinitesimal height and different radii place one on the other such that margin of between real and intended volume is minimum.

Step-by-step explanation:

A spherical slab is characterized by the radius as its inherent variable and cylindrical slabs by its radius and height. The volume of the spherical slab can be approximated by summing cylindrical slabs of infinitesimal height and different radii place one on the other such that margin of between real and intended volume is minimum. (Please see image attached below for further details).
