Step-by-step explanation:
i hope this helps!
I would say there would be 5 itineraries ie one each for Thailand, Singapore, Hong Kong, Laos and Bali though for the countries Thailand and Laos there may be more than one stop so there would be a minimum of 5 itineraries.
The Pythagorean identity is
sin²Ф + cos²Ф=1
or
sin²Ф= 1- cos²Ф
Now in the problem we are given that
cos Ф=3/5
Now to find sin Ф, we can plug the value of cos Ф in the identity
So
sin²Ф= 1- cos²Ф = 1-(3/5)² = 1- 9/25 = (25-9)/25 = 16/25
Sin²Ф= 16/25
take square root on both sides
Now when we take square root on both sides we have to always remember that we will get one positive and one negative answer
So
Sin Ф = 4/5 or -4/5
Answer: 90 seconds or 1 min. and 30 sec.
Step-by-step explanation:
72/4=18
18x5=90
25% or 1/4 because 5 is 25 percent of 20 and if you change 25% into a decimal you get .25 which is equivalent to 1/4
