shtirl [24]

The question is incomplete. The complete question is :

Davison Electronics manufactures two LCD television monitors, identified as model A and model B. Each model has its lowest possible production cost when produced on Davison’s new production line. However, the new production line does not have the capacity to handle the total production of both models. As a result, at least some of the production must be routed to a higher-cost, old production line. The following table shows the minimum production requirements for next month, the production line capacities in units per month, and the production cost per unit for each production line:

                      Production per unit                         Minimum production

Model        New Line        Old Line                              requirements

A                   $30                $50                                          50,000

B                   $25                $40                                           70,000

Production  80000          60000

line capacity.

Let

AN- Units of model A produced on the new production line

AO Units of model A produced on the old production line

BN Units of model B produced on the new production line

BO Units of model B produced on the old production line

Davison's objective is to determine the minimum cost production plan. The computer solution is shown in Figure 3.21.

a. Formulate the linear programming model for this problem using the following four constraints:

Constraint 1: Minimum production for model A

Constraint 2: Minimum production for model B

Constraint 3: Capacity of the new production line

Constraint 4: Capacity of the old production line  

Solution :

<u>Linear programming model</u>:

Linear programming is defined as a mathematical model where the linear function is either minimize or maximize when they are subjected to some constraints.

The linear programming model is determined as follows :

Minimum : 30 AN + 50 AO + 25 BN + 40 BO

This is subject to the constraints as :

AN+AO \geq 60,000

BN+BO \geq 70,000

AN+BN \leq 80,000

AO+BO \leq 60,000

A pizza parlor offers 4 different pizza toppings. How many different kinds of 2-topping pizzas are available?
Galina-37 [17]
Order does not matter so use "n choose k" formula is used to find number of unique combinations.

c=n!/(k!(n-k)!)  where n is total possible choices and k is number of selections.

c=4!/(2!(4-2)!)

c=4!/(2!2!)

c=24/(2*2)

c=24/4

c=6

So there are 6 different two topping options when there are four different toppings to choose from.

Kono divides The numerator and the denominator of 4872 by the greatest common factor to simplify the fraction in one step by wha
lakkis [162]

Complete question:

Kono divides The numerator and the denominator of 48 over 72 by the greatest common factor to simplify the fraction in one step by what number does he divide

Answer:

2/3

Step-by-step explanation:

Given the number : 48 / 72

Obtain the greatest common factor of 48 and 72

- - - - 48 - - - - 72

- 2-- 24 - - - - 36

- 2 - 12 - - - - - 18

- 2 - 6 - - - - - - 9

- 3 - 2 - - - - - - 3

The greatest common factor of 48 and 72 is hence (2 * 2 * 2 * 3) = 24

Hence, divide both the numerator and denominator by 24 ;

Numerator = 48/24 = 2

Denominator = 72 / 24 = 3

= 2/3

I need help plz ...i need this done by today !!!!

​5. At First Street Elementary School, about 18% of the 610 students ride bicycles to school. About how many students ride bicycles to school?

Since 100% is equal to 610 students​

​Then 18% is equal to X students

Results X students = 18%*610students/100% = 109.8 students. As it does not make sense to split students, we have to round up to the nearest unit. Then we have 110 students. That would be approximately 18.03%, that rounded to the nearest unit is approximately 18%.​

Answer 5) 110 students ride bicycles to school.​

​6. Write a proportion and answer each question using the conversion factor 1 inch = 2.54 centimeters.

a) Don is 67 inches tall. How many centimeters tall is he?​

Since 1 inch is equal to 2.54 centimeters​

Then 67 inches will be  X centimeters​

Results X cm = 67in * 2.54cm/1in = 170.18 centimeters​

Answer 6a) Don is 170.18 centimeters tall.​

b) Amira's pencil is 13.5 centimeters long. How many inches long is it?​

Since 2.54cm is equal to 1in​ch

​Then 13.5cm will be  X inches

Results X inches = 13.5cm * 1in/2.54cm ≈ 5.315 approximately 5.32 inches​

​Answer 6b) Amira's pencil is approximately 5.32 inches long.

7. Use dimensional analysis to convert 60 miles per hour to feet per second.​ Remember that there are 5,280 feet in 1 mile.

​Since 1 mile is equal to 5,280 feet

Then 60 miles will be  X feet​

Results X feet = 60 miles * 5,280 feet/1 mile = 316,800 feet​

Since there are 3,600 seconds in 1 hour​

316,800 feets per hour = 316,800 feets/hour x 1hour/3,600secs = 88 feet/sec​

Answer 7) 60 miles per hour are converted to 88 feets per second​

​Hope this helps!​​​​
