Answer:

64.8<em>cm</em> =<em> x</em> + <em>y</em>

The maximum sleeve length, <em>x</em>, plus the maximum allowable deviation,<em> y</em>, is 62.2<em>cm</em> = <em>x</em> - <em>y</em>

Step-by-step explanation:

The minimum sleeve length is the ideal length, <em>x</em>, minus the maximum allowable deviation,<em> y</em>.

64.8<em>cm</em> + 62.2<em>cm</em> = <em>x</em> + <em>y</em> + <em>x</em> - <em>y</em>

127.0<em>cm</em> = 2<em>x</em>

63.5<em>cm</em> =<em> x</em>

There are now two equations with two unknowns so both variable can be solved for.

Add the equations together and solve for the ideal length,<em> x</em>.

64.8<em>cm</em> = 63.5<em>cm</em> + <em>y</em>

1.3<em>cm</em> = <em>y</em>

Substitute <em>x</em> into either of the original equations and solve for<em> y</em>.

Result:

<em>x</em> = 63.5<em>cm</em>

±<em>y</em> = ±1.3<em>cm</em>

HERE'S HOW TO DO IT :)

A composite figure is made up of several simple geometric figures such as triangles, rectangles, squares, circles, and semicircles.

<u>To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together.</u>

<u>(SEE EXAMPLE ATTACHED)</u>

<u>HERES WHAT WE KNOW ABOUT COMPOSITE FIGURES:</u>

<u>Composite Figures. A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape). For example, figure ABCD is a composite figure as it consists of two basic figures</u>

Apply the zero matirx:<br> [16 -24] + [ 0 0 ]=[ x y]<br> X=? Y=?
Ainat [17]

Answer:

x = 16

y = -24

Step-by-step explanation:

Recall that the addition of matrices is done when matrices are of the same dimension. In this case, you are in fact adding matrices of the same dimension (dimension 1x2). Recall as well that in the addition of matrices, the elements of each matrix combine only with the element located in the exact same position in the other matrix.

So for this case the first element of the first matrix "16" combines with the first element of the second matrix "0" resulting in an element of value16 + 0 =16 in the new matrix.

Equally, the second element of the first matrix "-24" combines with the second element of the second matrix, resulting in : -24 + 0 = -24.

Therefore, the matrix resultant from this addition is: [16   -24] (same form of the first matrix, which indicates that adding a zero matrix to an existing matrix will not change the first matrix.

Fh. = 40h + 120,  fh. = $200

200 = 40h + 120
200 - 120 = 40h
80 = 40h
 80/40  = h
  2 = h

h = 2 hours.

Circumference = PI x Diameter

circumference of tire = 3.14 x 1.1 = 3.454 feet

 so every full turn of the tire the bike travels 3.454 feet

110 feet / 3.454 =  31.8 turns
