A company has two factories, factory A and factory B. The cost per item to produce q items in factory A is 200 + 3q q . The cost per item to produce q items in factory B is 400 + q 3q . Find an expression for the sum of these costs per item. Then divide this expression by 2 to find an expression for the average cost per item to produce q items in each factory.

Answers

Answer:

100

Step-by-step explanation:

200+3qq+400+q3q

200+3q²+400+3q²

3q²-3q²+400-200    

q²=200

q²=200/2

q²=100

HELP ME I WILL GIVE BRAINLIEST California has a population of approximately 4 × 10^7 people and South Dakota has a population of approximately 8 × 10^5 people.

Answers

The population in California is 50 times greater than the population in South Dakota.

The number of times the population in California is higher than that in South Dakota

To find out how many times greater the population in California is than in South Dakota, you can divide the population of California by the population of South Dakota:

Population of California = 4 * 10⁷

Population of South Dakota = 8 * 10⁵

Population ratio = (Population of California) / (Population of South Dakota)

Population ratio = (4 * 10⁷) / (8 * 10⁵)

Population ratio = 50

Therefore the population in California is 50 times greater than the population in South Dakota.

The perimeter of a rectangle is 38 units. The length is 13 units longer than the width. What are the dimensions of the rectangle?

Answers

Answer:

3 units ×16 units

Step-by-step explanation:

Please see the attached picture for full solution.

Answer:

Length = x+13=6+13=19units

Step-by-step explanation:

P = 2(l +w)

Let width be x

Length = x + 13

P = 38

38 = 2(x + 13 + x)

38 = 2(2x + 13)

38 = 2x + 26

2x = 38 - 26

2x = 12

x = 12/2

x = 6unit

Width = 6units

Length = x + 13 = 6+13 = 19units
