Carrie is searching online for airline tickets to weeks ago the cost to fly from Hartford to Boston was 210 now the cost is $350 what is the percent increase

It is a 40% increase

Step-by-step explanation:

So first of all the formula is

New-old/old

Or rate of change/ original

SO th new is 350

THe old is 210

350-210=140

140/350 which is old is 2/5

2/5 is 40 percent

So 40 percent increase

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
