1.5×12=18
300÷18=16.6667
you need to work close to 17 hours to earn that much when rounded to the nearest number.
Answer:
A and D.
Step-by-step explanation:
(sin(x-y))/(cosxcosy)
(sinxcosy - cosxsiny) / cosxcosy
= sinx / cosx - siny/cosy
= tanx - tany.
So A is an identity.
B. (sin(x+y))/(sinxsiny)
= sinx cosy + cosx siny / sinxsiny
= cosy/siny + cosx/sinx
= 1/tany + 1/tanx which is not identical with 1-tanxtany.
C. tan ( x - pi/4) = ( tan x - 1) / (1 + tanx) : - not identical to tanx - 1.
D. cos( x + (pi/6) = cosxcos(pi/6) - sinxsin(pi/6)
= 0.866cosx - 0.5sinx
- sin(x - (pi/3) = -(sinxcos(pi/3) - cosxsin(p/3))
= - (0.5sinx - 0.866cosx0
= 0.866cos x - 0.5sinx.
which are identical.
It would take them 8.5 hours.
Explanation:
Since they are painting the room together, they would basically each paint half of the room. So if they were painting half of the room each, it would take them half of the time that it would
normally take each of them. Half of Sally's time is 3.5 hours. And half of John's time is 5 hours. When you add them together, you get 8.5 hours.

Answer:
look at the explanation
Step-by-step explanation:
Write an equation:
Trash a way : $25 + 0.25x
Garbage No More : $45 per month
so to make them equal we need to have enough trash in Trash A Way that it equals $45
25 + 0.25x =45
0.25x = 20
x = 80
So, you need to have 80 pounds of trash to make them equal
