A more detailed explanation:

Alice:
6 hours = 1 room
1 hour = 1/6 of the room
Tom:
10 hours = 1 room
1 hour = 1/10 of the room
Alice and Tom together:
1 hour = 1/6 + 1/10 = 4/15 of the room
4/15 of the room = 1 hour
1/15 of the room = 1 ÷ 4 = 1/4 hour
15/15 of the room = 1/4 x 15 = 15/4 = 3 3/4 hours
Answer: They will take 3 3/4 hours to paint the room together.
14 days = 2 weeks so
14 times 3 = 42
So i believe you need to round the whole number, if so than 8 * 3 = 24 and 20 * 3 = 60
Answer:
cos(84)
Step-by-step explanation:
cosAcosB - sinAsinB = cos(A+B)
cos(52)cos(32) - sin(52)sin(32)
= cos(52+32) = cos(84)
Or 0.1045
