The minimal completion time for the activities is the shortest possible time for all the activities to be finished. In doing this, we look at the path that would require the greatest amount of time. At the START node, we choose the path that would take the longest which is 7 days leading to ACTIVITY D. Next, we choose the path leading to ACTIVITY B which takes 5 days. Then, we move to ACTIVITY C taking 5 days and finally, reach the END which would take 6 days. So, the minimal completion time is:
7 + 5 + 5 + 6 = 23 days
This is the concept of trigonometry, we are required to calculate the number of floors the building has given the information above;
# floors=[height of the building]/[height of each floor]
height of each floor=17 ft
let the height of the building be,h.
h is given by;
tan theta=opposite/adjacent
theta=80
opposite=h
adjacent=75 ft
thus
tan 80=h/75
h=75 tan 80
h=425.35 ft
thus the number of floors will be:
425.35/17
=25.020≈25 floors
Answer:
60 minutes
Step-by-step explanation:
to find this, we will first determine how long it takes austin to run one mile.
18 miles / 180 minutes
1 mile / 10 minutes
it takes austin to run 10 minutes to run 1 mile
now, we will multiply the number of minutes it takes by 6 to find how long it takes austin to run 6 miles.
1 mile / 10 minutes
6 miles / 60 minutes
it takes austin 60 minutes to run 6 miles
