Given:

W(width) = (6L) - 9

L(length) = L

Equation:

2( [ 6L ] - 9) + 2 (L) = 150

= 12L - 18 + 2L = 150

= 12L + 2L = 150 + 18

=14L = 168

L = 168/14, so the length is 12. Let's check our work.

Width:  6(12) - 9 = 72 - 9 = 63

Length: 12

Since there are two lines of width and two lines of length:

2(12) + 2(63) = 24 + 126, which gives you a perimeter of 150 mm.

Hope this helped.

)if there are 8 parts in a product and they are each at 6 sigma with a 1.5 shift, determine the ppm for the product
Maru [420]

Answer:

ppm value = 0.000027 parts per million

Step-by-step explanation:

Given:

number of parts(n) = 8

From table: percent conformance in six sigma = 0.9999966

Using the formula of ppm value in terms of percent conformance and number of parts:

ppm\,value = ( 1 -( \frac{percent\,conformance}{100} )^n )

Plugging in the values:

ppm\,value = (1 - (\frac{0.9999966}{100} )^8 )

ppm\,value = ( 1- 0.999972)\\

ppm\,value = 0.000027\,parts\,per\,million

IMAX Movie Prices. There were 322 people at a recent showing of the IMAX 3D movie "300". Admission was $8.75 each for adults and
dsp73

Answer:

218 adults and 104 children attended.

Step-by-step explanation:

From the information given, you can write the following equations:

x+y=322 (1)

8.75x+6y=2531.50 (2), where:

x is the number of adults

y is the number of children

First, you can solve for x in (1):

x=322-y (3)

Then, you can replace (3) in (2) and solve for y:

8.75(322-y)+6y=2531.50

2817.5-8.75y+6y=2531.50

2817.5-2531.50=8.75y-6y

286=2.75y

y=286/2.75

y=104

Finally, you can replace the value of y in (3) to find x:

x=322-104

x=218

According to this, the answer is that 218 adults and 104 children attended.
