DochEvi [55]

Answer:

x = 15

Step-by-step explanation:

+7/4  +7/4                 Add 7/4 to both sides

15/4 = 1/4x                Divide both sides by 1/4

15 = x

In a company, it takes 4 employees 4 days to complete a task. It would take 2 employees 8 days to complete the same task.
Triss [41]
The concept that can be used in order to answer this item is that of man-days. The total number of man-days required to do the job should always be constant. 

This can be illustrated by the givens above.
Scenario 1: 
     N1 = (4 employees)(4 days) = 16 man-days

Scenario 2:
    N2 = (2 employees)(8 days) = 16 man-days

The equation for determining the value of e is equal to,
     k = (d)(e)

The answer is the second choice.

Answer:

\fbox {Trapezoid ABCD and Trapezoid EFGH are congruent.}

Step-by-step explanation:

<u>Finding corresponding side lengths</u> :

<u>Trapezium ABCD</u>

  • AB = √(-2)² + (-1)² = √5
  • BC = √(-1)² + (2)² = √5
  • CD = √(2)² + (2)² = 2√2
  • DA = √(-1)² + (5)² = √26

<u>Trapezium EFGH</u>

  • EF = √(2)² + (1)² = √5
  • FG = √(1)² + (2)² = √5
  • GH = √(-2)² + (2)² = 2√2
  • HE = √(1)² + (5)² = √26

As the corresponding side lengths are equal, we can conclude that the trapezoids are congruent.
