3. A clothing manufacturing company makes two types of jogging pants, design A and design B. the design A jogging pants sells to

andriy [413]

Answer:

z(max) = 256000 Php

x₁ = 10

x₂ = 110

Step-by-step explanation:

Jogging pants design Selling Price Cost

weekly production

Design A x₁ 2500 1750

Design B x₂ 2100 1200

1. z ( function is : )

z = 2500*x₁ + 2100*x₂ to maximize

First constraint weekly production

x₁ + x₂ ≤ 120

Second constraint Budget

1750*x₁ + 1200*x₂ ≤ 150000

Then the model is

z = 2500*x₁ + 2100*x₂ to maximize

Subject to

x₁ + x₂ ≤ 120

1750*x₁ + 1200*x₂ ≤ 150000

General constraints x₁ ≥ 0 x₂ ≥ 0 both integers

First table

z x₁ x₂ s₁ s₂ cte

1 -2500 -2100 0 0 0

0 1 1 1 0 = 120

0 1750 1200 0 1 = 150000

Using AtoZmath online solver and after 6 iterations the solution is:

z(max) = 256000 Php

x₁ = 10

x₂ = 110

A camping leader bought the items listed in the table for his team. What is the average cost of an item in his purchase?

Rudik [331]

The right answer is Option D: $5.44

Step-by-step explanation:

Given,

Cost of one sun visor = $6.25

Cost of 11 sun visors = 6.25*11 = $68.75

Cost of one sunglasses = $8.90

Cost of 4 sunglasses = 8.90*4 = $35.60

Cost of one water bottle = $9.50

Cost of 8 water bottles = 9.50*8 = $76

Cost of one whistle = $1.75

Cost of 15 whistles = 1.75*15 = $26.25

Total number of items = 11+4+8+15 = 38

Total cost of items = 68.75+35.60+76+26.25 = $206.60

Average = $\frac{Sum\ of\ prices}{No.\ of\ items}$

$Average=\frac{206.60}{38}\\Average=\$5.436$

Rounding off to nearest hundredth

Average = $5.44

The average price of an item is $5.44

The right answer is Option D: $5.44

taurus [48]

Step-by-step explanation:

<h2>GIVEN:-</h2>

The Perimeter of Equilateral triangle = 60cm

<h2>UNDERSTANDING THE CONCEPT:-</h2>

According to the question,

To find the height of the triangle,

Perimeter of Equilateral triangle = Area of Equilateral triangle.

<h2>FORMULA USED:-</h2>

$60 = \frac{ \sqrt{3} }{4} a {}^{2} \\$

<h2>REQUIRED ANSWER:-</h2>

$60 \times 4 = \sqrt{3a {}^{2} }$

$a {}^{2} = 240 \sqrt{3} \\$

$a = 120 \sqrt{3} cm$

<h3>SO, The Exact height of the triangle is 120√3cm.</h3>
