Harry’s company can store 50,000 units of their new product in the warehouse, the maximum capacity for the warehouse. They sold
Nat2105 [25]

The company will take 47 weeks to fill the warehouse to its maximum capacity based on the current production rate.

<h3>What is an equation?</h3>

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Maximum capacity for the warehouse = 50,000 units

Pre-orders = 20,000 units

Number of units produced per week = 3000 units

Number of orders per week = 1500 units

The number of weeks to fill the warehouse to its maximum capacity:

We can make an equation as:

3000M - 1500M - 20,000 = 50,000 ____(1)

M = number of weeks

From (1) we get,

M ( 3000 - 1500 ) - 20,000 = 50,000 ____(2)

1500M - 20,000 = 50,000

1500M = 50,000 + 20,000

1500M = 70,000

M = 46.66 weeks

M = 47 weeks

We can also see that,

From (2),

M ( 3000 - 1500 ) - 20,000

47 x 1500 - 20,000

70,500 - 20,000

50,500

Thus,

The company will take 47 weeks to fill the warehouse to its maximum capacity based on the current production rate.

Write an expression that represents the<br> perimeter of this picture frame.
Nitella [24]

Answer:

6x+2

Step-by-step explanation:

The perimeter is all of the sides added together.

We know that in a rectangle, sides that are parallel to each other are the same.

So, to find the expression that represents the perimeter, you have to multiply 2x+1 by 2 and x by 2 and add both of those together.

(2*(2x+1))+(2*(x))

(4x+2)+(2x)

4x+2+2x

6x+2

5% of 50 = 2.5

8% of 50 = 4

12% of 50 = 6
