Roughly you are 30 times more protected with that sunscreen than without it. Some think of it as being able to be in the sun 30 times longer without burning than without. They can be in the sun 5 minutes before burning so with 30+ SPF, they can be in the sun 150 minutes ( 2.5 hours) before burning. Not true. Sunscreen breaks down as you wear it, the same way make-up fades from your face. The longer you go between applications of sunscreen, the more likely you are to burn. Reapply per the manufacture's directions, and more often if you sweat and after drying off. Just like foundation, when you sweat or touch your face, it comes off. 30+SPF is the Spectral(Sun) Protection Factor, not Spectral Burn Proof Factor ;)
30 + 30 + 30 + 30 + 30 + 30 = 180

The result of the equation - 130 plus 80 plus 60 plus 30, is found as follows;130 + 80 + 60 + 30= ( 130 + 80 ) + 60 + 30= 210 + ( 60 + 30 )= 210 + 90= 300Answer = 300
26+26+30=82 mean= 82 / 3 therefore mean=27.333333
30 + 30 + 30 + 30 + 30 + 30 = 180
Assuming you mean n2 + 11n + 30, the factors are (n + 6)(n + 5).
If you mean: 10+4r = 30 then it works out that r = 5
if by thrity equals you mean straight up 30, then the answer is 10.
If you mean 4h+6 = 30 then h has a value of 6
It has been recommended my medical experts that you should apply sun-screen with a minimum Sun Protection Factor (SPF) of 30. SPF 30 means it can protect you 30 times better than if you didn't have it. Remember that even if you have sunscreen on, you can still get sunburnt. The best sun protection is still shade. Avoid the sun during 11am and 2pm where the sun is most intense.

-30 plus 60 = 30

If you mean -5(6n+6) = 30 then -30n -30 = 30 and so n = -2 when evaluated
