Sun protection must be used during the hours of a. 6: 00 pm to 8: 00 pm. b. 10: 00 am to 2: 00 pm. c. 2: 00 pm to 6: 00 pm. d. 8: 00 am to 10: 00 am.

B

Explanation:

UVB rays are strongest between the hours of 10:00 AM to 2:00 PM.. Make every effort to minimize your time outdoors during these hours . And remember, the closer you live to the equator, the stronger the sun's rays for more hours in the day, since there is more daylight in these areas..

b

Explanation:

what ? ? clarify

a, b, c - sides of a triangle

a + b > c

a + c > b

b + c > a

we have a = 5m and b = 11m. substitute:

5 + 11 > c

16 > c → c < 16

5 + c > 11         subtract 5 from both sides

c > 6

11 + c > 5         subtract 11 from both sides

c > -6

c < 16 and c > 6 and c > -6

thereofre your answer is 6m < c < 16m
