N the following Earliest Start Time (EST) graph, assume each unit of time is an hour.

How long does it take to do just task E?

Group of answer choices

4

6

8

14

4

Step-by-step explanation:

It takes 4 hours to do task E using the route:  start ⇒B⇒E

It will take 6 hours to do task E if using route : start ⇒C ⇒E

Taking the shortest route, it will take 4 hours

You can apply the critical path method to identify the shortest route possible. First , specify the activity and look for their dependencies.Using the activity diagram, establish the activity completion time.Finally, identify the critical path using the best case estimate.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
